What happens if you only get the first COVID vaccine and not the second dose?


This question was answered live at the virtual conference titled, "Don’t Hesitate to Vaccinate! Our Experts Tell You Why" recorded on January 28, 2021.

Short Answer: 

You will need 2 COVID vaccines in order for them to work.


It takes time for your body to build protection after any vaccination. COVID vaccines that require 2 shots may not protect you until a week or two after your second shot. You can wait up to three weeks from the first dose to get the second dose. Recently the CDC has come out that you can go out as far as three weeks between the COVID vaccine doses because some people are travelling for work, or another unique circumstance.
