Tuesday, March 6, 2021 (HealthDay News)-the sooner pregnant A new small study shows that after a woman receives the COVID-19 vaccine, she is more likely to transfer protective antibodies to the baby.
Study co-author Dr. Emily Miller said: “This will only provide extra motivation to those who are on the wall, or they just think,’Maybe I will wait until after I give birth.’ She is from Northwestern University School of Medicine. Assistant Professor of Obstetrics and Gynecology and Physician of Fetal Medicine.
“We strongly recommend that you get vaccine During pregnancy. However, if you are worried that vaccinations will harm your baby, then these data tell us the opposite is true. Vaccines are a mechanism to protect your baby, and the sooner you get the vaccine, the better. “Miller said in a university press release.
Researchers analyzed the blood of 27 pregnant women who were vaccinated by Pfizer or Moderna Third trimester. They also analyzed the cord blood of their 28 newborns (26 singletons, twins).
This study shows that these women have a strong immune response after vaccination, which shows that the vaccine can protect pregnant women from COVID-19.
The study also found that the longer time between vaccination and delivery is related to the greater transfer of COVID-19 antibodies to the baby.
Only three babies (including twins) in the study were born without antibodies. Their two mothers received their first COVID vaccine less than three weeks before delivery.
The study also found that mothers who received the second two doses of vaccine before delivery were more likely to transfer COVID-19 antibodies to their babies.
In a previously published study by another institution, researchers analyzed 10 umbilical cord samples and made similar findings.
However, there are many issues that need further study.
Since the COVID-19 vaccine was only available at the end of last year, it is not known whether vaccinations in the early stages of pregnancy will result in more antibodies being transferred to the baby, but Miller believes it will.
She also said that it is too early to tell how long or how long the antibody transferred from the mother to the baby will protect the baby.
It is unclear how pregnancy complications affect the transfer of antibodies from the vaccinated mother to the baby.
The survey results were published on April 1 American Journal of Obstetrics and Gynecology.
