There have been no studies , atleast to my knowledge, of vaccine usage on pregnancy or the result of vaccination in pregnancy.
Vaccination at non
pregnant stage is perfectly fine and should be done as soon as possible. If you are already pregnant avoid getting vaccinated untill you consult your OBGYN.
Also, there have been no studies for comparison between different vaccines .
Next Steps
Follow up with your OBGYN regarding vaccination of you are already
pregnant or you think you might be.
