Vaccination Administration Guidelines

General Recommendations

  • The Centers for Disease Control and Prevention recommends that inactivated vaccines, including the shingles vaccine, can be safely and effectively administered simultaneously with or after other vaccines like COVID-19 and influenza vaccines 1
  • COVID-19 vaccines can be administered concurrently with influenza vaccines, and the shingles vaccine can be added to this combination without safety concerns 1
  • When administering multiple vaccines simultaneously, they should be given at separate anatomic sites to minimize local reactions 1
  • Individual vaccines should not be mixed in the same syringe unless specifically licensed for mixing by the FDA 1

Timing and Safety Considerations

  • There is no need to delay vaccination to administer these vaccines separately when they can be given simultaneously or in sequence 1
  • If administering vaccines with increased reactogenicity, they should be injected into different limbs to minimize local reactions 1
  • For live vaccines, if not administered simultaneously with other live vaccines, at least 4 weeks should pass between administrations 1
  • Studies have shown that simultaneous administration of vaccines elicits satisfactory antibody responses without increasing the incidence or severity of adverse reactions 1

Special Populations and Considerations

  • The American College of Rheumatology has identified the need to evaluate the impact of coadministration of COVID-19 vaccines given concurrently with other non-live virus vaccines on vaccine immunogenicity and tolerability 2
  • For patients on immunomodulatory therapies, the American College of Rheumatology provides guidance on timing vaccinations, but these recommendations do not specifically contraindicate administering shingles vaccines after COVID-19 and flu vaccines 3, 4, 5
