Messenger RNA covid-19 vaccines tozinameran (Comirnaty°) and elasomeran (Spikevax°) during pregnancy

in focusWhat main points should pregnant women be aware of in order to make informed decisions about covid-19 vaccination?

Key points

  • Pregnant women who become infected with Sars-CoV-2 are at higher risk of developing severe forms of covid-19 and potentially fatal complications, especially towards the end of pregnancy. These complications are more common in women with at least one risk factor, such as diabetes or hypertension.
  • In view of the consequences of covid-19 in pregnant women and the observed efficacy of the vaccines against the main variants prevalent in 2020 and 2021, the data available in early 2022 suggest that vaccination with tozinameran is useful for pregnant women, ideally between 10 weeks’ and 20 weeks’ gestation.
  • Vaccination helps, but does not replace, other preventive measures.
