Background:The process of generating immunity against a particular disease is known as immunization. The present study was conducted to assess the immunization status of children aged 1-5 years & the awareness level of the parents regarding the immunization of their children. Materials & Methods:152 children aged 1-5 years of both genders were selected. Parameters such as religion, socio-economic status, etc. were recorded. Results: out of 152 patients, males were 80 and females were 72. The age group 1-2 years had 56, 2-3 years had 36, 3-4 years had 32, and 4-5 years had 28 subjects. The difference was non- significant (P> 0.05). In Hindu, immunization status was complete in 65, partial in 10, and unimmunized in 8. In Muslim in 31, 4 and 5 and in Sikh in 10, 16, and 3 subjects respectively. The difference was significant (P< 0.05). In upper SES, immunization status was complete, partial, and unimmunized seen in 46, 9, and 5 subjects. In the middle was 36, 6, 4 and lower in 24, 15 and 7 respectively. The difference was significant (P< 0.05). Conclusion: Age, religion, and socioeconomic level all had a big impact on vaccination rates. According to our study, the main causes of partial immunization were the children's present diseases and ignorance of the vaccine schedule.
