title: Epidemiologic consequences of moderate coverage levels of measles vaccine in a district headquarter town (Alwar) in India, 1996.
abstract: This paper describes the epidemiology of measles in a medium size town (population 240,000) in India where vaccine coverage levels have remained constant at around 70 per cent in the past 7 years. A retrospective community survey covering 4023 children under 10 years old detected 252 cases of measles in the previous year. This gave an annual incidence of 6.3 per cent (95 per cent CI 5.5-7). About half of the cases occurred in vaccinated children. Only 5 per cent of the cases occurred in children below 9 months of age. This age is appropriate for routine measles immunization. Despite modest coverage levels with only 54 per cent effective vaccine (estimated by a screening method), there was a modest upward shift in the age distribution of measles cases; the median age was more than 48 months.
