Essential nutritive and immunological ingredients abundantly present in breastmilk make it the choice infant nutrition. The uniqueness of mother's milk, in contrast to most therapeutics and immunizations, lies in its potential to adapt itself to the requirements of the infant so that timely immune defenses are tapped from its constituents by immune regulation, modulation and immune acceleration to stimulate novel substances; these render it pertinent as defense when faced with challenging organisms. While it is appreciated that immunity can be transferred from mother to infant through breastmilk following maternal influenza vaccination, the immense benefits conferred by breastfeeding per se during influenza pandemics may not be fully valued. This is substantiated by debates and ambiguities for continued breastfeeding in the face of maternal influenza infections. This article emphasises the utmost importance of breastfeeding in viral pandemics in the light of the changing immunological strategies used by viruses at different times and the urgent need for such opportune defenses. The prolific interaction of its constituents is frequently understated as enormous advantages to the suckling infant.
Globally, rotaviral vaccines in use today have contributed to the reduction of the incidence of rotaviral diarrhoeas. Despite the substantial protection conferred by the current vaccines against the rotaviral strains, it is only prudent to recognise that other protective factors, like breastfeeding, also provide some degree of protection against this disease. This article has attempted to review some important mechanisms of protection in breast milk against the rotaviruses and highlight the oft forgotten non-immunoglobulin fraction in breast milk as an additional tool of protection against rotavirus disease. The adaptive capacity of breast milk to environment is another compelling reason to continue breastfeeding as it can usefully complement and be significant in the use of many vaccines. Vital immunoprotective constituents in breast milk beneficially protect the infant by initiating and strengthening many immune responses and should be borne in mind as essential tools of defence even in an era where vaccines play a pivotal role in the combat against certain diseases. It is impressive that besides nutritive advantages, the suckling infant enjoys appreciable immunoprotection via exclusive breastfeeding.
