Pregnant and Lactating People

A growing body of evidence on the safety and effectiveness of COVID-19 vaccination indicates the benefits of vaccination outweigh any known or potential risks of COVID-19 vaccination during pregnancy.

COVID-19 vaccination is recommended for:

  • Pregnant people
  • Lactating people
  • People trying to get pregnant now or who might become pregnant in the future

If a person becomes pregnant following the first dose of a COVID-19 vaccine that requires two doses (i.e. mRNA vaccines), administer the second dose as indicated for the person to have maximum protection.

However, you should talk to women younger than 50 years old who choose to receive the Janssen COVID-19 Vaccine about:

  • The rare but increased risk of thrombosis with thrombocytopenia syndrome (TTS) after receipt of this vaccine
  • The availability of other FDA-authorized COVID-19 vaccines (i.e., mRNA vaccines) where this risk has not been observed
