Healthcare Workforce
HCPs should either be fully immunized or present laboratory evidence of immunity, laboratory confirmation of disease, or diagnosis or verification of a history of varicella or herpes zoster by a healthcare provider.
Those without evidence of immunity should receive:
- 2 doses of varicella vaccine 4 to 8 weeks apart, or
- If previously received 1 dose, the 2nd dose at least 4 weeks after the 1st dose.
Recently vaccinated HCP do not require any restriction in their work activities; however, HCP who develop a vaccine-related rash after vaccination should avoid contact with persons without evidence of immunity to varicella who are at risk for severe disease and complications until all lesions resolve (i.e., are crusted over) or, if they develop lesions that do not crust (macules and papules only), until no new lesions appear within a 24-hour period.
