What is Involved?

If you choose to join this study, you will get a random assignment (like a coin flip) to either:

Get your COVID-19 and flu vaccinations on the same day; OR
Get the vaccines spaced out by 1-2 weeks from each other

Your participation in this study will end 90 days after you have your baby. You will visit our clinic up to 5 times during the study, and we will call you 3 times to check in on how you are doing. You will also have up to 4 blood draws during the study when you come in for your clinic visits.
