HCP Born in 1957 or Later
For healthcare personnel (HCP) born in 1957 or later without serologic evidence of immunity or prior vaccination, give 2 doses of MMR, 4 weeks apart. HCP born in 1957 can be considered immune to measles, mumps, or rubella only if they have documentation of:
A) laboratory confirmation of disease or immunity or
B) appropriate vaccination against measles, mumps, and rubella (i.e., 2 doses of live measles and mumps vaccine given on or after the first birthday and separated by 28 days or more, and at least 1 dose of live rubella vaccine).
HCP with 2 documented doses of MMR are not recommended to be serologically tested for immunity. If they are tested and results are negative or equivocal for measles, mumps, and/or rubella, these HCP should be considered to have presumptive evidence of immunity to measles, mumps, and/or rubella and are not in need of additional MMR doses.
Any HCP born prior to 1957 is considered acceptable enough evidence to measles, mumps, and rubella immunity. 2 doses of MMR vaccine should be considered for unvaccinated HCP born before 1957 who do not have laboratory evidence of disease or immunity to measles and/or mumps. One dose of MMR vaccine should be considered for HCP with no laboratory evidence of disease or immunity to rubella.
For HCP who do not have evidence of immunity, 2 doses of MMR vaccine are recommended during an outbreak of measles or mumps and 1 dose during an outbreak of rubella. HCP who have had 2 doses of MMR and are identified by public health authorities as being at an increased risk for mumps because of an outbreak should receive a third doses of MMR to improve protection.
