After receiving the smallpox vaccine, in 3-4 days a red, itchy bump forms. In the first week the bump develops into a blister, then fills with pus, and drains. In the second week, the blister dries up and begins to scab over. In the third week, the scab falls off, leaving a scar. For a few days after the vaccination, a person can get fever, chills, and swollen lymph nodes. These minor local reactions are expected as a part of the immunization process. Other local reactions that are self-limiting, do not require medical attention, are intense redness and swelling at the immunization site, and swelling and tenderness of lymph nodes for up to 2-4 weeks after the immunization site has healed.
