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.
In this situation, Shingrix can be given at the same visit or at any time after the varicella vaccine. The person will still need to complete the 2-dose schedule. If Shingrix is not available and Zostavax is used in this situation, a dose of zoster vaccine should be given at the same visit. If this is not possible Zostavax can be given at least 4 weeks after the varicella vaccine.
