Temporal Analysis of Vaccination Rates and Disease Incidence in Chennai District: A Statistical Approach

Dr. S. Subbulakshmi, Dr. R. Sasikumar

Abstract: This study presents a temporal analysis of vaccination coverage and the incidence of vaccine-preventable diseases in Chennai District, Tamil Nadu, India, from 2010 to 2020. Using secondary data obtained from the Tamil Nadu Health Department and National Health Mission (NHM), the research employs time-series and regression models to quantify the relationship between immunization rates and disease incidence for diseases such as measles, diphtheria, and pertussis. The findings indicate a statistically significant inverse correlation, reinforcing the role of sustained vaccination efforts in urban public health systems. The results suggest policy implications for strengthening immunization programs and early warning systems in metropolitan areas.

Keywords: Chennai District, vaccination coverage, disease incidence, time-series analysis, regression modeling, public health, measles, diphtheria, pertussis, lag models, Tamil Nadu, immunization trends
