This update aligns with and clarifies the ACIP 2011 Immunization of Healthcare Personnel Recommendations

Update: Susceptible healthcare personnel (HCP) should not enter room if immune care providers are available; regardless of presumptive evidence of immunity, HCP should use respiratory protection that is at least as protective as a fit-tested, NIOSH-certified N95 respirator upon entry into the patient’s room or care area. For exposed susceptibles, postexposure vaccine within 72 hours or immune globulin within 6 days when available [17, 1032, 1034].  Place exposed susceptible patients on Airborne Precautions and exclude susceptible healthcare personnel.
