Do breastfed babies have immunity from RSV?

Understanding RSV and Breastfeeding
Respiratory Syncytial Virus (RSV) is a significant concern for infants, being the leading cause of severe respiratory infections in this vulnerable population. Each year, RSV leads to millions of hospitalizations and thousands of deaths worldwide, particularly affecting premature babies and those with underlying health conditions. Given the serious nature of RSV, many parents wonder about the protective effects of breastfeeding against this virus.
The Protective Role of Breastfeeding
Research indicates that breastfeeding can indeed provide a protective effect against RSV. A study highlighted that breastfeeding is associated with a reduced frequency of infections, including those caused by RSV. The World Health Organization (WHO) emphasizes the importance of exclusive breastfeeding for at least six months, as this duration is linked to maximal immune protection against various viral infections, including RSV.
Breast milk contains antibodies and other immune-boosting components that help fortify an infant’s immune system. This passive immunity is particularly crucial in the early months of life when infants are most susceptible to infections. The longer a baby is breastfed, the greater the potential for protection against respiratory infections.
Limitations and Additional Measures
While breastfeeding offers significant benefits, it is important to note that it does not guarantee complete immunity from RSV. Infants are universally exposed to the virus, and while breastfeeding can reduce the severity and incidence of RSV infections, it does not eliminate the risk entirely. Therefore, health organizations recommend additional protective measures, such as vaccinations for mothers during pregnancy and the administration of RSV antibodies to infants, to further safeguard against severe RSV infections.
Conclusion
In summary, breastfeeding plays a vital role in enhancing an infant’s immunity against RSV, contributing to lower rates of infection and severity when infections do occur. However, it should be viewed as part of a broader strategy for protecting infants from RSV, which includes vaccinations and other preventive measures. As parents navigate the complexities of infant health, understanding the benefits of breastfeeding can empower them to make informed choices for their child’s well-being.

Adaptive Immunity to RSV and Vaccination. Natural infection gives us few clues about adaptive protection against RSV. Following infection, protection generated is short-lived and incomplete, allowing RSV to re-infect the host throughout life (80).

Can mom pass RSV antibodies to baby?

Maternal RSV vaccine (Pfizer’s Abrysvo)
