If a person received varicella vaccine inadvertently when a zoster vaccine was indicated, there are no specific safety concerns unless the person was immunocompromised, but the dose should not be considered valid.
A dose of zoster vaccine should be given at the same visit. If this is not possible, Shingrix can be given at any time after the varicella vaccine, or Zostavax can be given at least 4 weeks after the varicella vaccine. If the individual is administered Shingrix, they will still need to complete the 2-dose schedule.
