Does It Matter Which COVID-19 Vaccine You Get?

Does it matter which vaccine I get? Any vaccine approved or authorized in the United States has gone through rigorous clinical trials and has been thoroughly tested. So any vaccine offered to you should do a good job of preventing COVID. The two vaccines currently authorized, Pfizer and Moderna, have both demonstrated nearly 95% effectiveness. Whatever vaccine you're given, you want to follow your doctor's orders. Both require two shots, but the timing is slightly different. And it's important you get both doses.
