Pfizer Coronavirus Vaccine Proves To Be 78% Effective In Pregnancy
The results of a new study have found that the is only 78% effective in preventing a .
The study was spearheaded by researchers at Maccabi Healthcare Services, located in Tel Aviv, Israel, and its results were recently published in the journal . In total, they considered 15,060 pregnant participants over the course of their study.
Half of the expecting women (7,530) received the first dose of the Pfizer vaccine sometime between December 19, 2020, and February 28, 2021. The rest of the pregnancy participants didn’t receive the vaccine. The participants were monitored until April 11, 2021.
In order to control for other variables, the researchers ensured the participants were similar in:
- Area of residence
- Population subgroup
- How far along in pregnancy
- Whether they received the flu shot
46% of the vaccinated group were in their second and third trimester, while only 33% of the unvaccinated group was this far along.
Only a small minority of the vaccinated women contracted coronavirus after their first dose. Specifically, only 118 of the vaccinated participants (1.6%) contracted the virus within 28 days of their first shot. This compares to 202 of the unvaccinated women (2.7%) who also became infected during the same time period.
Even more, between 28 to 70 days following the first dose, 10 of the vaccinated women tested positive in comparison to 46 unvaccinated mothers-to-be who became sick.
Additionally, the unvaccinated women were more likely to require hospitalization. Only 0.2% of the vaccinated women were admitted to hospital, compared to 0.3% of the unvaccinated women.

While the study demonstrates the vaccine is effective in preventing coronavirus in pregnancy when compared to those who choose not to get vaccinated, it’s not as effective as initially reported.
The for instance, reports that the Pfizer vaccine has been proven to be upwards of 95% effective. More research is needed to confirm whether the vaccine’s success drops in pregnancy, or if earlier vaccine trials overestimated Pfizer’s efficacy.
At the moment, are underway in order to better understand their implications for pregnant women. Similarly, . Earlier this year, the youngest person to receive both doses of a coronavirus vaccine was an . According to reports, the infant was doing well following the vaccine.
