Seroprevalence of measles antibodies among high-risk healthcare workers in Auckland, New Zealand: additional justification for assumption of age-determined immunity based on local data.
An outbreak of measles in another region of New Zealand prompted our organization to review the measles immunity of healthcare workers. Some studies suggest that age-specific immunity cannot be assumed. In our local setting, however, we found that 893 (98%) of 912 healthcare workers more than 40 years old tested seropositive for measles immunoglobulin G.
