What about long-term effects of the COVID-19 vaccine?

Health care workers answer questions about the COVID-19 vaccines.

Jessica Malaty Rivera, MS explains that there isn’t any risk of long-term effects from the COVID-19 vaccines.

The amount of time that the MRNA is actually in your body is probably 48 hours. And then after that, the only thing that remains is the memory of that vaccine. The kind of memory of what the spike protein looks like, so that if the body ever encounters the spike protein in an infection, it knows how to fight it. So, because of that, we feel very confident that there isn’t any risk of long-term effects because the vaccine is not actually a part of your body for a very long time.
