Measles is a highly contagious vaccine-preventable disease caused by the Morbilivirus. Measles vaccine was introduced in India in 1985 as a part of Universal Immunization Programme (UIP) which was given at 9 completed months of age. As vaccine coverage has increased, there has been a marked reduction in measles incidence in the pediatric age group; but at the same time, the average age, at which measles infection occurs, has significantly increased. Many countries have reported diminishing of antibody titres against measles among young population as immunization coverage of adolescents and adults in not monitored. Objective is to determine seroprevalence of IgG antibodies titres against measles in young adults. It is a cross sectional study, conducted over 6 months (JUNE to NOVEMBER 2018) Sample size is 200. Study population belonged to 15-30 yrs of age. Samples – serum (Blood) Measles IgG ELISA Kit (EUROIMMUN). Out of the 200 samples collected, had protective titres, of the study group showed susceptibility . they had unprotective levels of antibody titres and were in the borderline titre group. Most of the individuals were vaccinated with a single dose of measles vaccine. Several reports have shown that the susceptibility to measles infection may be rising because of waning vaccine induced immunity over time after vaccination, in the absence of natural boosting by circulating measles viruses While most of the immunization drives in developing countries are aimed at children, it is important to recognize and identify pockets of susceptible populations that could jeopardize the prevention and control of these vaccine preventable diseases. Hence there is a need for serosurveillance and mop -up programs to cover these pockets of susceptible population so as to reach the WHO goal of Measles Eradication by 2020. | Seroprevalence of measles antibodies among young adults in a tertiary care Hospital, India
