Аннотация
A prospective immunogenicity trial of measles and rubella vaccines was conducted in Oman. Children received measles vaccine at age 9 months and measles-rubella vaccine at age 15 months. Serum specimens were tested for measles-specific IgG and rubella-specific IgG. Of 1025 eligible infants, 881 (86.0%) returned for all five visits and had adequate serum samples for testing. Seroconversion to measles after vaccination at 9 months was 98.1%. At 15 months, 47 (5.3%) of the 881 children were seronegative for measles; of these, 44 (93.6%) seroconverted. At 16 months, 99% of the children seronegative at age 9 months seroconverted after receiving two doses of measles vaccine. At age 15 months, 684 (77.6%) children were seronegative for rubella. Of these, 676 (98.8%) seroconverted by age 16 months. One dose of measles vaccine at age 9 months was highly immunogenic. One dose of measles-rubella vaccine at age 15 months closed the remaining measles immunogenicity gap and resulted in a high rate of rubella seroconversion.
