According to a few, small new studies, vaccinated moms-to-be may actually be able to pass COVID-19 antibodies to their newborns.
Study on COVID-19 vaccine passed antibodies their kids:
A study from Providence Portland Medical Center found that breastfeeding moms who had gotten the COVID-19 vaccine passed antibodies their kids, potentially protecting them against the virus. It’s important to note this was a small, pilot study and only looked at six breastfeeding women.
These women had gotten both their doses of the Pfzier or Moderna vaccine between December 2020 and January 2021. Researchers collected breast milk samples from the women before their vaccinations and 11 times afterwards, with the last sample collected two weeks after their second dose of the vaccine. The researchers found that starting seven days after the initial vaccine dose, there were higher levels of COVID-19 antibodies in the breast milk.
A second study from Tel Aviv University and the Tel Aviv Sourasky Medical Center also found that vaccinated pregnant women were able to pass antibodies to their newborn through breast milk. The study looked at 10 women who had received both doses and tested the antibody levels in their blood and breastmilk on four separate occasions afterwards. The researchers found that the antibody levels increased two weeks after the first dose, continuing until seven days after the second dose. They also found that the antibodies blocked the COVID-19 virus and believe this may help prevent the infection in newborns and babies.
Vaccine and pregnancy:Few things you need to know:
Did you know a baby gets disease immunity (protection) from mom during pregnancy? Getting the flu shot and Tdap vaccine while you’re pregnant causes your body to create protective antibodies and you pass on some of those antibodies to your baby.
2. Maternal vaccines are very safe…for you and your little one.
Tdap and flu vaccines are very safe for you and your baby. CDC and a panel of experts who make vaccine recommendations have concluded that they are safe for pregnant women and their babies. These experts carefully reviewed the available safety data before recommending Tdap and flu vaccines during pregnancy.
Vaccines are like any medicine, which means they can have some side effects. But most people who get vaccinated have no side effects.
3. Whooping cough can be really dangerous for your baby.
You’ll need a Tdap vaccine during the 27th through 36th week of each pregnancy. Tdap protects against whooping cough, which can be life-threatening for newborns. About half of babies younger than 1 year old who get whooping cough need treatment in the hospital.
The younger the baby is when she gets whooping cough, the more likely the baby will need to be treated in a hospital.
“The encouraging data show that vaccinating breastfeeding mothers promotes the production of important antibodies in their breast milk, potentially protecting their nursing babies from the disease,” Dr. Yariv Wine, a researcher on the study and PhD candidate Aya Kigel from the TAU Shmunis School of Biomedicine and Cancer Research, told The Jerusalem Post.
The study is still being peer reviewed. Several researchers are currently working to find out more on how COVID-19 antibodies passed from mom to baby could help offer protection.
In the past, studies have shown that moms who get COVID-19 may pass antibodies onto their babies. Now, this study is showing that vaccines delivered to pregnant women may help offer the same protection.
