    Introduction Cervical cancer caused by the human papilloma virus (HPV) is a common cancer in women. There is no published data on the recent incidence of cervical dysplasia, cervical cancer and genital warts caused by the different types of HPVs in Brunei Darussalam.
    Methods A cross-sectional, retrospective study was conducted utilising data from patients diagnosed with cervical cancer during the period 2005–2009 in Brunei Darussalam. The varying incidences of different types of cervical lesions among various ethnic and age groups, and in the overall population, were determined.
    Results The mean age-standardised incidence of invasive cervical cancer during the five-year period was 24.9 per 100,000 women per year (95% confidence interval [CI] 21.7, 28.1). Age-specific invasive cervical cancer incidence peaked in the age group 45–59 years. Chinese females tended to have a higher incidence of invasive cervical cancer (28.2 per 100,000 women per year; 95% CI 17.8, 38.7) than Malay females (20.6 per 100,000 women per year; 95%
    CI 17.1, 24.2), while other ethnic groups in Brunei Darussalam had a significantly lower incidence (6.5 per 100,000 women per year; 95% CI 3.0, 10.0).
    Conclusion The results suggest that Brunei Darussalam has a relatively higher incidence of cervical cancer compared to its neighbouring countries. The findings support the need for more comprehensive screening, public education programmes and vaccination against HPV in the country.

    A qualitative study design was adapted to explore the challenges faced by health workers (HWs) during the polio health campaign. In addition, HWs' opinions about the factors causing parents to refuse oral polio vaccination (OPV) were also explored. Four focus group discussions (FGDs) were held (from 1st January 2015-31st March 2015) with the HWs who participated in the OPV campaigns in the polio red zones of Khyber Pakhtoon Khawa (KPK) province of Pakistan, namely Kohat (FG 1), Domel and Bannu (FG 2), Hangoo (FG 3), and Peshawar (FG 4). A total of N=42 HWs (10-11 in each FG) agreed to participate in this study. Overall, HWs disclosed that public attitude and harsh behaviour towards the HWs and security threats are the two main challenges they face. Common issues hindering parents' willingness to vaccinate their children against OPV are: OPV is seen as haram and not permitted in Islam, it is said to contain the blood of pigs (Khinzir) and monkeys, and parents are afraid that it is done to induce sterility among their children. HWs also shared that parents have a strong belief in the conspiracies that are associated with OPV, i.e. the USA and CIA, are spying on us and our government is helping them to achieve their agenda. Furthermore, HWs revealed that frequent visits may further strengthen parents' perceptions and make them more resistant to OPV. The common side effects of OPV reported by parents were mainly gastro-intestinal problems and in some cases mild to moderate fever with some respiratory symptoms. There is a great need to improve the logistics and facilities for HWs assisting in vaccination programmes. Furthermore, it is necessary to improve education, so people understand the basic concept of revaccination and booster doses, thereby assisting in creating a basic understanding of vaccinations, which may trigger changes in attitudes and make people believe in the benefits of OPV rather than following the conspiracies that lead them to refuse it.

    The aim of this study was to investigate the clinico-pathology and haemato-biochemistry alterations in buffaloes inoculated with Pasteurella multocida type B:2 immunogen outer membrane protein via subcutaneous and oral routes. Nine buffalo heifers were divided equally into 3 treatment groups. Group 1 was inoculated orally with 10 mL of phosphate buffer saline (PBS); Group 2 and 3 were inoculated with 10 mL of outer membrane protein broth subcutaneously and orally respectively. Group 2 buffaloes showed typical haemorrhagic septicaemia clinical signs and were only able to survive for 72 h of the experiment. However, Group 3 buffaloes were able to survive throughout the stipulated time of 21 days of experiment. There were significant differences (p  0.05) in edema between groups except for the lung. This study was a proof that oral route infection of Pasteurella multocida type B:2 immunogen outer membrane protein can be used to stimulate host cell.

    INTRODUCTION: Vaccination is an effective way to overcome the spread of Coronavirus Disease 19 (COVID-19). However, it can give rise to adverse event following immunisation (AEFI). AEFI is an important aspect that is assessed in vaccine safety standards. It is assumed that different vaccine platforms can give rise to different degrees of AEFI severity, but so far there have been no studies that discuss the differences in the degree of AEFI on each type of COVID- 19 vaccine platform.

    AIM: Evaluate the differences in the degree of AEFI on each type of COVID-19 vaccine platform.

    MATERIALS AND METHODS: The research used a quantitative analytical observational design with a cross sectional approach. Data collection from participants was carried out by filling out questionnaires. The collected data was tabulated and statistical analysis was carried out.

    RESULTS: A total of 217 respondents who received three doses of vaccine participated in the study. Of the 651 vaccine doses studied, the results showed that there were significant differences in the degree of AEFI between the three types of vaccine platforms. The degree of AEFI was significantly different (p < 0.05) between each type of vaccine platform, with the degree of AEFI starting from the lowest, namely inactivated vaccine, then viral vector vaccine and the highest was nucleic acid vaccine.

    CONCLUSION: The degree of AEFI differs significantly between each COVID-19 vaccine platform. The degree of AEFI, from the mildest to the most severe, was inactivated vaccine, viral vector vaccine and nucleic acid vaccine. No serious AEFI was reported.

    OBJECTIVES: The success of the Expanded Program on Immunization among children will greatly reduce the burden of illness and disability from vaccine preventable diseases. The aim of the study was to evaluate the complete immunization coverage and its determinants among children aged 12-23 months in Malaysia.
    STUDY DESIGN: Cross-sectional study.
    METHODS: Data on immunization were extracted from the 2016 National Health and Morbidity Survey. Complete immunization coverage was classified as received all recommended primary vaccine doses by the age of 12 months and verified by vaccination cards, and incompletely immunized if they received partially recommended vaccine dose or not received any recommended vaccine dose or had no vaccination card. The multiple logistic regression analyses were conducted to determine the sociodemographic factors associated with complete immunization coverage.
    RESULTS: The overall complete immunization coverage among children (verified by cards) was 86.4% (n = 8920, 95% confidence interval: 85.4-87.4). Multivariable logistic regression analyses model revealed that factors significantly associated with complete immunization coverage were ethnicity, occupation of the mother, head of household's education level, and head of household's occupation. While sex, citizenship, household income, mother's age, and marital status were not significantly associated with complete immunization coverage.
    CONCLUSIONS: According to the World Health Organization criteria, the present study demonstrated that the immunization coverage of 86.4% is still unsatisfactory. Thus, the current intervention program should be enhanced in order to achieve the 95% coverage for all antigens in the national vaccination program.

    Cholera is a major infectious disease, affecting millions of lives annually. In endemic areas, implementation of vaccination strategy against cholera is vital. As the use of safer live vaccine that can induce protective immunity against Vibrio cholerae O139 infection is a promising approach for immunization, we have designed VCUSM21P, an oral cholera vaccine candidate, which has ctxA that encodes A subunit of ctx and mutated rtxA/C, ace and zot mutations. VCUSM21P was found not to disassemble the actin of HEp2 cells. It colonized the mice intestine approximately 1 log lower than that of the Wild Type (WT) strain obtained from Hospital Universiti Sains Malaysia. In the ileal loop assay, unlike WT challenge, 1×10⁶ and 1×10⁸ colony forming unit (CFU) of VCUSM21P was not reactogenic in non-immunized rabbits. Whereas, the reactogenicity caused by the WT in rabbits immunized with 1×10¹⁰ CFU of VCUSM21P was found to be reduced as evidenced by absence of fluid in loops administered with 1×10²-1×10⁷ CFU of WT. Oral immunization using 1×10¹⁰ CFU of VCUSM21P induced both IgA and IgG against Cholera Toxin (CT) and O139 lipopolysaccharides (LPS). The serum vibriocidal antibody titer had a peak rise of 2560 fold on week 4. Following Removable Intestinal Tie Adult Rabbit Diarrhoea (RITARD) experiment, the non-immunized rabbits were found not to be protected against lethal challenge with 1×10⁹ CFU WT, but 100% of immunized rabbits survived the challenge. In the past eleven years, V. cholerae O139 induced cholera has not been observed. However, attenuated VCUSM21P vaccine could be used for vaccination program against potentially fatal endemic or emerging cholera caused by V. cholerae O139.

    Various studies conducted in Indonesia have shown that administration of Vitamin A to pre-school children had decreased the mortality and morbidity rates among them. In the first study conducted in the province of Acheh in North Sumatra, a twice yearly high dose of vitamin A led to a 34% decrease in mortality. In a second study in Bogor, conducted by fortifying the nutritional additive MSG with vitamin A and distributing the product in a designated area, the mortality rate among preschool children was 45% less than in a control area. In the third study also conducted in Bogor, where vitamin A was given to lactating women 2 weeks after giving birth and then directly to the infants themselves after 5 months of age, the mortality rate was 38% lower. The prevalences of respiratory and diarrhoeal infections were statistically lower than in the control gorups. Another study on preschool children showed a two-fold increase of anti TT IgG on primary immunisation against tetanus when compared to a control group and a four-fold increase with a secondary immunisation. Other studies conducted in Bogor and other parts of the world have showed that smaller doses given more often are more effective than bigger doses given less often.

    Intravenous immunoglobulin (IVIG) therapy in Kawasaki disease (KD) has been shown to reduce coronary artery aneurysm by 4-5%. However, we still observed significant number of coronary aneurysm post IVIG in our centre. The objectives of this study were to determine the prevalence of coronary artery abnormality (CAA) and the associated risk factors.
    Designs: Retrospective descriptive study. Method: A retrospective study performed on children with KD from 1 st January 2005 to 30 th July 2010. Japanese Ministry of Health criteria were used to classify coronary arteries abnormality. Children with incomplete or atypical KD were excluded. Data were extracted from Pediatric Cardiology Clinical Information System.
    Results: A total of 126 KD were diagnosed during the study period with 69% were male and 52.4% were Chinese. The median age of diagnosis was 1.4yr [Q1, 0.6yr Q3, 2.3yr]. Of these 126, 118 (93.7%) received IVIG within 10 days of illness. Ten patients (7.9%) required more than one dose of IVIG. CAA were noted in 28 (22.2%) patients with 21 ectasia, 4 small fusiform, one small saccular and 2 medium fusiform aneurysm. Of these 28, 22 who had IVIG within 10 days of illness (18 ectasia, 3 small and one medium coronary aneurysm) Significant risk factors for CAA were older children (2.3 v s 1.7yr, p=0.03), presentation after 10days of illness (p=0.006) and required more than 2gm/kg of IVIG (p=0.04).
    Conclusion: CAA in complete KD treated with IVIG was 22.2% with 5.5% significant aneurysm. Risk factors for coronary abnormality were older children, late presentation and require more of IVIG of than 2gm/kg.

    BACKGROUND: Although pneumococcal conjugate vaccines (PCVs) have been available for prevention of invasive pneumococcal disease (IPD) caused by Streptococcus pneumoniae (S. pneumoniae) for over a decade, their adoption into national immunization programmes in low- and middle-income countries (LMICs) is still limited. Economic evaluations (EEs) play a crucial role in support of evidence-informed decisions.

    OBJECTIVE: This systematic review aims to provide a critical summary of EEs of PCVs and identify key drivers of EE findings in LMICs.

    METHODS: We searched Scopus, ISI Web of Science, PubMed, Embase and Cochrane Central from their inception to 30 September 2015 and limited the search to LMICs. The search was undertaken using the search strings 'pneumococc* AND conjugat* AND (vaccin* OR immun*)' AND 'economic OR cost-effectiveness OR cost-benefit OR cost-utility OR cost-effectiveness OR cost-benefit OR cost-utility' in the abstract, title or keyword fields. To be included, each study had to be a full EE of a PCV and conducted for an LMIC. Studies were extracted and reviewed by two authors. The review involved standard extraction of the study overview or the characteristics of the study, key drivers or parameters of the EE, assumptions behind the analyses and major areas of uncertainty.

    RESULTS: Out of 134 records identified, 22 articles were included. Seven studies used a Markov model for analysis, while 15 studies used a decision-tree analytic model. Eighteen studies performed a cost-utility analysis (CUA), with disability-adjusted life-years, quality-adjusted life-years or life-years gained as a measure of health outcome, while four studies focused only on cost-effectiveness analysis (CEA). Both CEA and CUA findings were provided by eight studies. Herd effects and serotype replacement were considered in 10 and 13 studies, respectively. The current evidence shows that both the 10-valent and 13-valent PCVs are probably cost effective in comparison with the 7-valent PCV or no vaccination. The most influential parameters were vaccine efficacy and coverage (in 16 of 22 studies), vaccine price (in 13 of 22 studies), disease incidence (in 11 of 22 studies), mortality from IPD and pneumonia (in 8 of 22 studies) and herd effects (in 4 of 22 studies). The findings were found to be supportive of the products owned by the manufacturers.

    CONCLUSION: Our review demonstrated that an infant PCV programme was a cost-effective intervention in most LMICs (in 20 of 22 studies included). The results were sensitive to vaccine efficacy, price, burden of disease and sponsorship. Decision makers should consider EE findings and affordability before adoption of PCVs.

    Background On August 24, 2011, 31 US-bound refugees from Kuala Lumpur, Malaysia (KL) arrived in Los Angeles. One of them was diagnosed with measles post-arrival. He exposed others during a flight, and persons in the community while disembarking and seeking medical care. As a result, 9 cases of measles were identified. Methods We estimated costs of response to this outbreak and conducted a comparative cost analysis examining what might have happened had all US-bound refugees been vaccinated before leaving Malaysia. Results State-by-state costs differed and variously included vaccination, hospitalization, medical visits, and contact tracing with costs ranging from $621 to $35,115. The total of domestic and IOM Malaysia reported costs for US-bound refugees were $137,505 [range: $134,531 - $142,777 from a sensitivity analysis]. Had all US-bound refugees been vaccinated while in Malaysia, it would have cost approximately $19,646 and could have prevented 8 measles cases. Conclusion A vaccination program for US-bound refugees, supporting a complete vaccination for US-bound refugees, could improve refugees' health, reduce importations of vaccine-preventable diseases in the United States, and avert measles response activities and costs.

    Respiratory syncytial virus (RSV) chest infection is a common cause of hospitalization in the very young child. The aim of this study was to determine the direct cost of resource utilization in the treatment of children hospitalized with RSV chest infection and the potential cost-savings with passive immunization for high-risk infants. An audit of the hospital resource consumption and its costs was performed for 216 children aged < 24 mo admitted with RSV chest infection between 1995 and 1997. The cost-saving potential of passive immunization using monoclonal RSV antibodies during the RSV season was determined by assuming an 0.55 efficacy in hospitalization reduction when administered to "high-risk" infants according to the guidelines outlined by the American Academy of Pediatrics (AAP). The hospital treatment cost of 1064 bed-days amounted to USD 64 277.70. Each child occupied a median of 4.0 bed-days at a median cost of USD 169.99 (IQ1 128.08, IQ3 248.47). Children, who were ex-premature or with an underlying illness were more likely to have a longer hospital stay, higher treatment costs and need for intensive care. Ten (42%) of 24 ex-premature infants fulfilled the recommended criteria for passive immunization. Its use resulted in an incremental cost of USD 31.39 to a potential cost saving of USD 0.91 per infant for each hospital day saved.

    CONCLUSION: Ex-prematurity and the presence of an underlying illness results in escalation of the direct treatment cost of RSV chest infection. Current guidelines for use of passive RSV immunization do not appear to be cost-effective if adopted for Malaysian infants.

    The primary objective of this paper is to serve as a valuable resource for policymakers who are confronted with the evolving landscape of the coronavirus disease 2019 (COVID-19), considering both free and cost-based vaccination approaches. The potential consequences of shifting from free to cost-based vaccination are explored, encompassing its impact on global vaccine equity and prioritization, economic well-being, healthcare systems and delivery, public health policies, and vaccine distribution strategies. Examining past studies on willingness to pay for the initial COVID-19 vaccine dose and booster shots provides insights into how individuals value COVID-19 vaccinations and underscores the significance of addressing issues related to affordability. If COVID-19 vaccinations incur expenses, using effective communication strategies that emphasize the importance of vaccination and personal health benefits can increase willingness to pay. Making COVID-19 vaccines accessible through public health programs or health insurance can help alleviate financial barriers and increase vaccination rates.

    Pneumococcal disease causes large morbidity, mortality and health care utilization and medical and non-medical costs, which can all be reduced by effective infant universal routine immunization programs with pneumococcal conjugate vaccines (PCV). We evaluated the clinical and economic benefits of such programs with either 10- or 13-valent PCVs in Malaysia and Hong Kong by using an age-stratified Markov cohort model with many country-specific inputs. The incremental cost per quality-adjusted life year (QALY) was calculated to compare PCV10 or PCV13 against no vaccination and PCV13 against PCV10 over a 10-year birth cohort's vaccination. Both payer and societal perspectives were used. PCV13 had better public health and economic outcomes than a PCV10 program across all scenarios considered. For example, in the base case scenario in Malaysia, PCV13 would reduce more cases of IPD (+2,296), pneumonia (+705,281), and acute otitis media (+376,967) and save more lives (+6,122) than PCV10. Similarly, in Hong Kong, PCV13 would reduce more cases of IPD cases (+529), pneumonia (+172,185), and acute otitis media (+37,727) and save more lives (+2,688) than PCV10. During the same time horizon, PCV13 would gain over 74,000 and 21,600 additional QALYs than PCV10 in Malaysia and Hong Kong, respectively. PCV13 would be cost saving when compared against similar program with PCV10, under both payer and societal perspective in both countries. PCV13 remained a better choice over PCV10 in multiple sensitivity, scenario, and probabilistic analyses. PCV13s broader serotype coverage in its formulation and herd effect compared against PCV10 were important drivers of differences in outcomes.

    BACKGROUND: The HPV vaccine was introduced to Malaysian national immunization programme in 2010. The current implementation age of HPV vaccination in Malaysian is at the age of 13 years school girls, given according to a 3 doses protocol which may complicate implementation and compliance. Aim of the study is to determine the cost-effectiveness of HPV vaccination regime comparing twice versus thrice HPV vaccinations dose regime among adolescent girls in Malaysia.

    METHODS: A Markov cohort model reflecting the natural history of HPV infection accounting for oncogenic and low-risk HPV was adapted for 13 year old Malaysian girls cohort (n = 274,050). Transition probabilities, utilities values, epidemiological and cost data were sourced from published literature and local data. Vaccine effectiveness was based on overall efficacy reported from 3-doses clinical trials, with the assumption that the 2-doses is non-inferior to the 3-doses allowing overall efficacy to be inferred from the 3-doses immunogenicity data. Price parity and life-long protection were assumed. The payer perspective was adopted, with appropriate discounting for costs (3 %) and outcomes (3 %). One way sensitivity analysis was conducted. The sensitivity analysis on cost of vaccine, vaccine coverage and discount rate with a 2-doses protocol was performed.

    RESULT: The 3-doses and 2-doses regimes showed same number of Cervical Cancers averted (361 cases); QALYs saved at 7,732,266. However, the lifetime protection under the 2-doses regime, showed a significant cost-savings of RM 36, 722,700 compared to the 3-doses scheme. The MOH Malaysia could vaccinate 137,025 more girls in this country using saving 2-doses regime vaccination programme. The model predicted that 2-doses HPV vaccination schemes can avoid additional 180 Cervical Cancers and 63 deaths compare to 3-doses.

    CONCLUSION: A 2-doses HPV vaccination scheme may enable Malaysian women to be protected at a lower cost than that achievable under a 3-doses scheme, while avoiding the same number of Cervical Cancer cases and deaths. Using the saving money with 2-doses, more Cervical Cancers and deaths can be avoided.

    Anti-idiotype (Id) vaccine therapy has been tested and shown to be effective, in several animal models, for triggering the immune system to induce specific and protective immunity against bacterial, viral and parasitic infections. The administration of anti-Id antibodies as surrogate tumor-associated antigens (TAA) also represents another potential application of the concept of the Id network. Limited experience in human trials using anti-Id to stimulate immunity against tumors has shown promising results. In this "counter-point" article, we discuss our own findings showing the potential of anti-Id antibody vaccines to be novel therapeutic approaches to various human cancers and also discuss where anti-Id vaccines may perform better than traditional multiple-epitope antigen vaccines.

    The introduction of human papillomavirus (HPV) vaccination in China aims to prevent HPV infection in all women. The issues that China might face include high cost of vaccines made in other countries, shortage in HPV vaccine supply, negative events attributed to vaccination (whether justified or not) that jeopardizes the general public's confidence in the HPV vaccine, cultural and literacy barriers, and sensitivity to receiving a vaccine for a sexually transmitted disease. Ensuring the effective delivery of the HPV vaccine in China, a country with vast economic, geographical, and cultural complexities, will require a commitment of significant resources. In light of the high price of imported vaccines, the availability of locally manufactured HPV vaccines would greatly facilitate the national HPV vaccination program. New evidence supporting the efficacy of a two-dose regime in younger adolescents would also be advantageous in terms of affordability and logistical simplicity of vaccine administration. Furthermore, it would potentially enhance the compliance and uptake, especially for hard to reach women in remote regions.

    Primary immunodeficiency disease (PID) or inborn error of immunity is a heterogeneous group of inherited diseases affecting the immune system resulting in increased susceptibility to infections, immune dysregulation, autoimmune manifestations, lymphoproliferation and malignancy. Cases of PIDs have been reported in Malaysia since 1977 and the numbers of reported cases steadily increased for the past 30 years with more trained clinical immunologist available, better immunodiagnostic facilities, wider immunoglobulin replacement therapy availability and improved techniques in haematopoietic stem cell transplantation for PIDs. In this article, we highlight some of the limitations and challenges in the diagnosis and therapy of PID, and more recent efforts to establish PID services in Malaysia.

    Malaysia is a rapidly developing country with a very young population, about 36% of which are below the age of 15 years. The standard of child health has improved greatly. However, there are great changes in the morbidity and mortality patterns of childhood diseases relating mainly to an improved standard of living; availability of safe water supply and adequate sanitary latrines; a higher literacy rate; rapid industrialisation and urban migration. The infant mortality rate has droppedfrom 50.1 per 1,000 livebirths in 1986 to 10.4 in 1995, and similar trends apply also to neonatal, perinatal and toddler mortality rates. Nevertheless, current major child health problems are those relating to events in the perinatal period and to infections. Despite improvements in the standard of neonatal care with the use ofhigh technology, the commonest cause of certified deaths still occur in the neonatal period. A rapid and inexpensive screening test for G6PD deficiency, a disease present in 2-3% of the population, is now widely available and, together with the use of phototherapy is largely responsible for the declining incidence of kernicterus in the country. Infections remain an important cause of morbidity and mortality although their patterns have changed. The very high (>95%) WHO-EPI-vaccines coverage rate is linked to the great reduction in the incidence of diphtheria, pertussis, tetanus, poliomyelitis and measles. Childhood tuberculosis is less common now, with about 250 - 300 reported cases per year and TB meningitis is rare with about 30-40 reported cases/year. The hepatitis B carrier rate is high (5%) and the introduction of routine newborn hepatitis B vaccination in 1989 is expected to have a positive impact as is the immunisation of young girls against rubella introduced in 1985 in reducing the incidence of congenital rubella syndrome. The incidence of malaria has declined but remains prevalent in the interiors of PeninsularMalaysia and in Sabah and Sarawak. Filariasis is largely under control. Unfortunately, despite great efforts at mosquito control, dengue virus infection remains a major problem with thousands of cases reported every year. Children are most susceptible to dengue haemorrhagic fever with many dying from the shock syndrome. The incidence of acute gastroenteritis has also dropped with most cases being due to a viral aetiology. Acute respiratory infections, mostly viral in origin, account for most attendances at paediatric outpatient services. Although staphylococcal and streptococcal impetigo and pneumonia are common, the incidence of streptococcal related diseases like rheumatic fever and acute glomendonephritis is rapidly declining. The nutritional status of children has improved in tandem with the rise in the standard of living, but subclinical malnutrition is prevalent, particularly among urban squatters and the rural poor. There is a disturbing decline in breastfeeding among urban working mothers. Poor weaning practices and food habits are responsible for the common occurrence of nutritional anaemia (5%) among infants and young children. Greater prosperity, rapid industrialisation and urbanisation have resulted in changes in the childhood disease pattern where non-communicable diseases assume greater importance as the problems of malnutrition and infection are gradually overcome. Road traffic accidents are a major killer and home accidents, largely preventable, are an important cause of morbidity and mortality. Childhood cancer, with about 550 new cases a year, is an important cause of death beyond infancy. Major congenital malformations, with a 1% prevalence rate, cause much ill-health. Thalassaemia is a particularly common genetic disease with fl thalassaemia gene frequency of about 5%. The prevalence of asthma is increasing, with a rate of 13.9% in the Kiang Valley but the prevalence of asthma-related symptoms is much higher. Physical, sexual child abuse and neglect, abandoned babies, substance abuse are but signs of stress of modern city living and peoples inability to cope with it. Although the general standard of child health has greatly improved, there are several states where it is still not satisfactory. In Sabah where there is a large illegal immigrant population, the infant mortality and infection rates are relatively high. In Kelantan and Trengganu, it is common for parents to refuse permission for a lumbar puncture required to treat meningitis. Other still deeply entrenched, culturally-related adverse health practices include : a fatalistic attitude to illness; a preference for traditional practitioners of medicine resulting in late treatment; and 'doctor-hopping' with unrealistic expectations of 'instant cure'. Childhood illnesses that are uncommon in Malaysia include: cystic fibrosis, coeliac disease, ulcerative colitis, Crohns disease, Sudden Infant Death Syndrome, Encopresis, enuresis and epiglottitis due to Haemophilus Influen:ae.

    Phage display technology is an important tool for antibody generation or selection. This study describes the development of a scFv library and the subsequent analysis of identified monoclonal antibodies against BmSXP, a recombinant antigen for lymphatic filariasis. The immune library was generated from blood of lymphatic filariasis infected individuals. A TA based intermediary cloning approach was used to increase cloning efficiency for the library construction process. A diverse immune scFv library of 10(8) was generated. Six unique monoclonal antibodies were identified from the 50 isolated clones against BmSXP. Analysis of the clones showed a bias for the IgHV3 and Vκ1 (45.5%) and IgHV2 and Vκ3 (27.3%) gene family. The most favored J segment for light chain is IgKJ1 (45.5%). The most favored D and J segment for heavy chain are IgHD6-13 (75%) and IgHJ3 (47.7%). The information may suggest a predisposition of certain V genes in antibody responses against lymphatic filariasis.
