Question: 

Should I be worried if I don’t get any side-effects? Does it mean the vaccine didn’t work?

Answer: 
 
It is true that side effects are normal signs that the vaccine is working and your body is building protection. However, this doesn’t mean you should be worried if you don’t have side-effects. For example, both the Pfizer and Moderna vaccines provided protective immunity to over 90% of recipients in the clinical trials, but more than 50% reported no side-effects. 
 
If you experience short term side effects after your second dose, including fever, muscle aches and joint aches, they are temporary and you will feel better in a few days. Call 8-1-1 if these side effects continue past a period of a few days.
