[A study on measles vaccination rate and its antibody level in children aged 12-24 months in Guangxi, 1989].

This report described the measles vaccination rate (MVR) as well as its HI antibodies of 1842 children aged from 12 to 24 months. The MVR was 99.57% but HI positive rate was only 83.50%. HI of 298 target children still remained negative. Among them, 6 children were unvaccinated and others vaccinated. The HI negative rate reached 16.50% The HI positive rate was higher in the target children who lived in the area with convenient transportation and relatively low atmospheric temperature, and who received measles vaccine at the age of 8 months or more. Otherwise, the HI positive rate was lower. So some suggestions were proposed that the vaccination season, age of vaccine, increasing vaccine dosage should be considered carefully before measles vaccination session had arranged.
