There are a number of common side effects of vaccines. Some of these side effects occur in only one in one hundred recipients, while others occur in up to half of the recipients. Fortunately, not all of the side effects on the list occur with each vaccine; some only occur with a few vaccines. Even better, all of these side effects are mild and transient and are usually gone within two to three days. You can find the complete list of side effects for any given vaccine on the appropriate VIS at www.immunize.org/vis.
