The duration of adverse reactions to the varicella vaccine varies from person to person. In most cases, adverse reactions occur within 1 to 2 days after vaccination, and in rare instances, they may appear within half a month. These adverse reactions mainly include mild fever, local redness, swelling, induration, and rash in some individuals. Generally, these symptoms last about one week and then gradually subside.
