Abstract
The tolerance and safety of vaccination in pregnancy should be assessed in local populations based on ethnic differences across countries. Therefore, this study aimed to determine the tolerability of the BNT162b2 mRNA vaccination in pregnancy in a Polish population. An online questionnaire enquiring about the safety and tolerability of the BNT162b2 mRNA vaccine was distributed to pregnant and non-pregnant female healthcare professionals who had voluntarily received one or two doses of the COVID-19 vaccine in Poland. The two groups were compared simultaneously considering the COVID-19 infection status before vaccination. Compared with that noted in the control group, pregnant women in the COVID-19-free group were less likely to have fever (p = 0.002) or gastrointestinal symptoms (p = 0.009) after the second dose. In the COVID-19-exposed group, pregnant women were less likely to experience local skin reactions (p = 0.009), and myalgia (p = 0.003) after the first dose. After the second dose, the only noticeable difference was a lower incidence of myalgia (p = 0.001) in pregnant women. The tolerability of the BNT162b2 mRNA COVID-19 vaccine was similar in both the groups. No severe local, generalised, or pregnancy complications related to mother or foetus were observed. Good tolerability of the BNT162b2 mRNA COVID-19 vaccine in pregnancy in the Polish population may facilitate the decision to vaccinate pregnant women against COVID-19.
Highlights
Evaluations of the tolerability and safety of coronavirus disease 2019 (COVID-19) vaccination during pregnancy are crucial during the ongoing pandemic
In the COVID-19-exposed group, women in the pregnancy and control subgroups were similar in terms of age (p = 0.242) and body mass index (BMI) (p = 0.098)
The evidence from the present study suggests that the BNT162b2 mRNA COVID-19 vaccine is safe and tolerable for women during pregnancy
Summary
Evaluations of the tolerability and safety of coronavirus disease 2019 (COVID-19) vaccination during pregnancy are crucial during the ongoing pandemic. We explored the tolerability of COVID-19 vaccination in pregnant Polish healthcare professionals. We conducted an online survey that yielded data from 180 female Polish healthcare professionals who received the BNT162b2 vaccine against COVID-19 while pregnant. We compared their survey responses with those of 40 age-matched female Polish healthcare professionals who received the same vaccine but were not pregnant
