Differences Between Vaccines

Some COVID-19 Vaccines Require More Than One Shot To be fully vaccinated, you will need two shots of some COVID-19 vaccines.

To be fully vaccinated, you will need two shots of some COVID-19 vaccines.

  • If you get a COVID-19 vaccine that requires two shots, you are considered fully vaccinated two weeks after your second shot. Pfizer-BioNTech and Moderna COVID-19 vaccines require two shots.
  • If you get a COVID-19 vaccine that requires one shot, you are considered fully vaccinated two weeks after your shot. Johnson & Johnson’s Janssen COVID-19 vaccine only requires one shot.
  • If it has been less than two weeks since your shot, or if you still need to get your second shot, you are NOT fully protected. Keep taking all prevention steps until you are fully vaccinated (two weeks after your final shot).

Is it safe for me to get a COVID-19 vaccine if I would like to have a baby one day?

Yes. If you are trying to become pregnant now or want to get pregnant in the future, you may receive a COVID-19 vaccine when one is available to you.

There is currently no evidence that COVID-19 vaccination causes any problems with pregnancy, including the development of the placenta. In addition, there is no evidence that fertility problems are a side effect of any vaccine, including COVID-19 vaccines.

Like all vaccines, scientists are studying COVID-19 vaccines carefully for side effects now and will continue to study them for many years.
