Do COVID Antibodies Pass Through Breast Milk?
The question of whether COVID-19 antibodies can be transmitted through breast milk has garnered significant attention, especially as the pandemic has evolved and vaccination efforts have ramped up. Recent studies have provided compelling evidence that mothers who have been vaccinated against COVID-19 can indeed pass antibodies to their infants through breast milk. This transmission is crucial as it offers a layer of protection for newborns and infants, who are particularly vulnerable to infections.
Research indicates that both IgA and IgG antibodies, which are vital components of the immune response, are present in the breast milk of vaccinated mothers. These antibodies have been shown to provide neutralization against the SARS-CoV-2 virus, the pathogen responsible for COVID-19 . This means that when a breastfeeding mother receives a vaccine, her body produces specific antibodies that can be transferred to her baby, potentially helping to bolster the infant’s immune defenses against the virus.
Moreover, studies have also explored the breast milk of mothers who have recovered from COVID-19. These investigations suggest that mothers who have had the virus also produce antibodies that can be found in their breast milk, further supporting the idea that breastfeeding can be a protective factor for infants. While the exact duration of these antibodies in breast milk remains a topic of ongoing research, their presence is a significant reason why breastfeeding is encouraged during the pandemic.
However, it is important to note that while breast milk can provide antibodies, it does not guarantee complete immunity for the infant. The antibodies may help reduce the severity of the illness if the baby does contract COVID-19, but they are not a foolproof shield against infection. Additionally, the transmission of the virus itself through breast milk has not been substantiated, which means that breastfeeding remains a safe practice for mothers who are infected or have recovered from COVID-19, provided they follow appropriate hygiene measures.
In conclusion, the transmission of COVID-19 antibodies through breast milk represents a significant advancement in understanding maternal-infant health during the pandemic. As research continues to evolve, the implications for breastfeeding practices and infant health remain a vital area of focus for healthcare providers and new parents alike.

Which antibodies are passed through breast milk?

A large part of immunoglobulins excreted in milk are IgA that protect mainly against enteric infections. The specificity of maternal milk IgA is driven by an entero-mammary cell circulation. Human milk also contains anti-idiotypic antibodies capable of enhancing infant antibody response.

Can viruses pass through breast milk?

Transmission occurs through contact with respiratory secretions, and droplet precautions are protective. No evidence suggests transmission through breast milk or breastfeeding.

Are there antibodies in breast milk from COVID booster?

Numerous studies have shown the presence of anti-SARS-CoV-2 antibodies in human milk after two doses of mRNA-based COVID-19 vaccines [10–21]. Specifically, IgA and IgG against the spike (S) protein of SARS-CoV-2 have been found in human milk after both vaccination and infection [7].

Can I be around my baby if I have COVID?

Isolate. Stay home and away from others, including the baby, as much as possible for the CDC’s recommend isolation period.

Do breastfeeding moms get sick less?

Breastfeeding has health benefits for both babies and mothers. Breast milk provides a baby with ideal nutrition and supports growth and development. Breastfeeding can also help protect baby and mom against certain illnesses and diseases.

Do breastfed babies recover from colds faster?

On the contrary, your milk is a powerful medicine that can help your little one recover more quickly! When your baby is sick, your milk may actually change its composition in response to the baby’s saliva, providing even more of the beneficial compounds babies need to get well.

Is it safe to breastfeed after a COVID vaccine?

In addition, recent studies demonstrate that your COVID-19 immunity can pass to the baby through the breast milk after you receive the vaccine. The Academy of Breastfeeding Medicine recommends that all breastfeeding individuals get a COVID-19 vaccine.

Can COVID be passed through breast milk?

Current evidence suggests that breast milk is not a source of transmission of SARS-CoV-2. When possible, breastfeeding mothers with suspected or confirmed COVID-19 should continue to breastfeed while taking hygiene precautions. This advice is regardless of COVID-19 vaccination status.

Can a mother pass COVID antibodies to a baby?

Evidence Builds That Pregnant Women Pass Covid Antibodies to Newborns. A new study suggests that protective antibodies can be transferred through the placenta, and the baby may receive more of them if a mother is infected with Covid earlier in her pregnancy.

Can having COVID while pregnant hurt the baby?

Moderate to severe symptoms from COVID-19 have also been linked to higher rates of preterm birth, high blood pressure or preeclampsia. These risks may shift as the virus that causes COVID-19 changes.
