After receiving herpes zoster vaccine, common reactions such as pain, redness and swelling may appear at the injection site, and in severe cases, reactions such as fever and vomiting may occur. 1. Common reactions: usually occur within a short period of time after shingles vaccination, and may be manifested as localized pain, redness and swelling at the injection site. Usually, the symptoms are mild and only need symptomatic treatment, which can be effectively relieved by localized hot compresses to promote local blood circulation. 2. Serious reaction: some people will have more serious reaction after receiving herpes zoster vaccine, which can be manifested as fever, high fever that does not go away, vomiting or even convulsions, etc., which is related to allergic reaction after vaccination, and need to seek medical treatment in time. The common herpes zoster vaccine is a genetically recombinant herpes zoster vaccine, so the risk of serious adverse reactions is very low. If local pain, redness, swelling and other manifestations occur after vaccination, symptomatic treatment such as local hot compresses can be used to achieve an effective relief effect, and if there are serious reactions such as high fever and convulsions, it is recommended to seek medical attention in a timely manner in order to avoid delaying the timing of treatment.
