During a measles vaccine trial in a rural area of Senegal, antibody status was examined within 10 days of exposure for 228 previously vaccinated and 313 unvaccinated children more than 12 months old who were exposed to measles at home. Thirty-six percent of the children developed clinical measles, the clinical diagnosis being confirmed for 135 of the 137 children from whom 2 blood samples were collected. Vaccine efficacy was 90% (95% confidence interval, 83 to 94%). The hemagglutinin-inhibiting… 

Measles immunity and response to revaccination among secondary school children in Cumbria

A simple inexpensive field assay would need to be developed before salivary screening and selective vaccination could substitute for universal vaccination of populations at risk of measles outbreaks.

Seroconversions in unvaccinated infants: further evidence for subclinical measles from vaccine trials in Niakhar, Senegal.

Although laboratory errors and inadvertent injection of vaccine rather than placebo may have played some role, they do not fully explain the above observations, which are consistent with subclinical measles in the seroconverters.

Seroepidemiological evaluation of 1989–91 mass vaccination campaigns against measles, in Italy

In 1989–91 anti-measles vaccination campaigns were conducted in several Italian regions to vaccinate all children aged between 13 months and 10–12 years without a history of measles or measles vaccination, and the strategy was able to unite natural and induced immunity.

Decline in measles case fatality ratio after the introduction of measles immunization in rural Senegal.

Measles immunization may contribute to lower mortality directly through reduced incidence and indirectly through increases in age at infection, less severe infection for immunized cases and changes in transmission patterns leading to reduced severity of measles.

Additional Evidence on Serological Correlates of Protection against Measles: An Observational Cohort Study among Once Vaccinated Children Exposed to Measles

This information supports the analyses of serosurveys to detect immunity gaps that require targeted intervention strategies in children with low vaccination coverage in the Netherlands.

Measles Antibodies Measured by Plaque Reduction Neutralization Test in Infants during the First Year of Life

The results indicate that measles vaccination at six months of age or older, which is the current recommendation during the period of epidemic issued by the Korean Society of Pediatrics, should not cause the primary vaccine failure.

Measles incidence, vaccine efficacy, and mortality in two urban African areas with high vaccination coverage.

It will be necessary to vaccinate before age 9 months to control measles in hyperendemic urban African areas, according to data examined prospectively in two districts in Bissau.

Duration of immunity following immunization with live measles vaccine: 15 years of observation in Zhejiang Province, China.

The results indicate that the immunity induced by successful primary immunization may persist for at least 15 years, and there were some indications that reimmunization might produce better effects if live attenuated measles virus were used with a longer interval between doses.

Sex-specific differences in mortality after high-titre measles immunization in rural Senegal.

For children aged 5-10 months the high-titre measles vaccine did not increase mortality relative to unvaccinated children who had received placebo, and the long-term survival after high-Titre Measles immunization at 5 months of age with that following routine immunization with standard- titre vaccine at 10 months ofAge.

Secondary measles vaccine failure in healthcare workers exposed to infected patients.

Four healthcare workers vaccinated in the past developed measles despite pre-existing antimeasles antibody levels and all had a significant rise in measles-specific IgG following infection, raising concerns regarding detection of adequate protective measles immunity.

P prospective immunologic studies confirmed that immunity persists after immunization as well as after natural measles infection, and reimmunization of children with undetectable HAI antibody induced a classic booster response.

Pattern of exposure and measles mortality in Senegal.

Postmeasles mortality through the year following measles infection was significantly related to the intensity of exposure, and differences in exposure may be a major determinant of child survival, both at time of acute disease and for the long term impact of measles infection.

Expanded programme on immunization.

Poliomyelitis immunization efforts have been so successful that the Pan American Health Organization is leading a drive to eradicate poliomyelinitis from the Americas by 1990.
