I had smallpox when I was 6 months old. Is it necessary to get a booster at 25?
Are there any side effects of the smallpox vaccine?
Side effects of the smallpox vaccine can include redness, swelling, and soreness at the injection site, as well as fever, malaise, and body aches. More serious side effects, such as allergic reactions, are rare.
