Socio demographic characteristics of infants who had received primary immunization

The goal of immunization is to protect the individual and the public from vaccine preventable diseases (VPDs). Vaccines are usually safe and effective. However, like any other pharmaceutical products, adverse events may occur occasionally following vaccination. The adverse events following immunization (AEFI) surveillance in India was started with the launch of Universal Immunization Program (UIP) in 1985 and intends to ensure the quality and safety of vaccines. A descriptive study was conducted at maternal and child health hospital involving infants and their mothers who delivered at the centre. The sample size was arrived by using the formula n=4pq/d 2 where prevalence “p” was taken as 55% (Measles vaccination at MCH hospital which is the least among all the vaccinations). With precision of 5%, using the above mentioned statistical formula which considers 95% confidence limits; the sample size was estimated to be 110. Most of the study subjects 60 (54.5 %) belonged to the nuclear family followed by 25 (22.7%) to three-generation family and 25 (22.8%) to joint family. Majority of subjects 47 (42.7%) belonged to lower middle class followed by 30 (27.3%) upper middle class, 22 (20%) upper lower class and 11 (10%) were upper class according to Modified Kuppuswamy socio-economic status classification 2016.
