If you take a shower right after vaccination, it may easily lead to infection of the injection site, so you should dry your whole body right after showering, especially the injection site, and then use relevant disinfectant such as iodophor or alcohol to strictly disinfect the local wounds and try to prevent the occurrence of infection. In addition, it is important to closely monitor the individual’s condition, if there are symptoms of allergy or discomfort, such as localized maculopapular rashes, hives or generalized rashes, it may be an allergic reaction to the vaccine, and you should go to the hospital immediately for injection of anti-inflammatory and anti-allergic drugs to control the local allergic symptoms.
