COVID-19 vaccine and pregnancy

18/02/2021

With COVID-19 pandemic everywhere, a lot of doubts are coming up these days, especially if you’re pregnant. Can I get vaccinated if I’m pregnant? Should I be vaccinated during my pregnancy? Is SARS-CoV-2 vaccine safe enough or it could be harmful for my baby?

Recently, WHO (World Health Organization) has changed its mind about vaccination in pregnant women. New data suggest SARS-CoV-2 vaccination should be performed in pregnant woman with high risk of infection (doctors, nurses, etc.) or with risk factors like diabetes, asthma, etc.

It doesn’t mean they recommend all pregnant women be vaccinated, but with current data they consider the vaccination benefits get over the potential risks in pregnant women highly exposed to SARS-CoV-2 due to their position or pregnant women with increased risk in case of contagion (because of their medical history).

As pregnant women were not included in clinical trials (they are always excluded in most of them), data are not available in this group, although no harmful effects were found in animals. Actually, vaccination during pregnancy is an usual practice in many other viruses (ex: flu virus).

The point is that mother COVID-19 antibodies go straight to the fetus, meaning that if the woman is vaccinated and produce antibodies the baby should be protected from SARS-CoV-2.

Actually, the antibodies would probably work in the same way as other vaccines (like flu vaccine antibodies), going through the placenta even more efficiently than the antibodies produced by a SARS-CoV-2 infection.
