If you need assistance finding a travel clinic, contact our team at 317.221.2122, and we can assist you in finding one.
Healthcare personnel (HCP)
Vaccine Recommendation:
- If no proof of immunity, HCP need 2 doses of varicella vaccine, at least 28 days apart.
- Proof of immunity includes documentation of prior vaccination.
- Clinician diagnosis or serological verification of a history of varicella or herpes zoster (shingles).
Vaccine Recommendation:
- If previously unvaccinated or partially vaccinated, HCP need a 2 or 3-dose series depending on the vaccine product. Obtain anti-HBs serologic testing 1–2 months after final dose for HCP who perform tasks that may involve exposure to blood or body fluids.
- Employers may require anti-HBs testing of HCP upon hire despite a record of hepatitis B vaccination in infancy or childhood. A negative anti-HBs test performed years after vaccination does not distinguish responders from non-responders due to waning immunity. It is recommended that HCP get tested, and if the anti-HBs is below 10 mlU/mL, they should receive an additional dose of hepatitis B vaccine and be retested 1-2 months later.
Vaccine Recommendation: Annual
HCP need documentation of 2 MMR given at least 28 days apart unless they have proof of immunity. Proof of immunity includes:
- Documentation of 2 doses of MMR vaccine.
- Laboratory evidence of immunity.
- Laboratory confirmation of disease.
HCP born before 1957:
- Verification of immune status may depend on the risk of exposure to measles within the facility.
- Consider getting vaccinated anyway.
- HCP need a one-time dose of Tdap as soon as possible if there has been no Tdap previously administered (regardless of when previous dose of Td was received).
- Td boosters every 10 years.
- All pregnant people, including pregnant HCP, should get a dose of Tdap during each pregnancy — preferably at 27-35 weeks’ gestation.
Vaccinate microbiologists that are routinely exposed to Neisseria meningitidis isolates:
- A dose of MenACWY; and boost every 5 years, if risk continues.
- The 2- or 3- dose series of Men B (depending on product used).
