Rubella susceptibility: a solo family physician survey.

Of patients seen in the office during one month, 156 were screened for rubella hemagglutination antibody (HI) after a clinical history of susceptibility was obtained. Of these, 64 (42%) believed that they had had clinical rubella and 18 (seven percent) that they had been vaccinated. When tested, 95 (63%) were found to be immune and the remaining 55 (37%) were offered vaccination.The vaccination was given to 28 patients, 22 of whom returned after three months for a repeat HI titer. Half of these (11) required a second vaccination and five of these had the vaccination in the office. Of these five, all showed no change in immunity after the second vaccination.
