Estimation of measles vaccination coverage using the Lot Quality Assurance Sampling (LQAS) method--Tamilnadu, India, 2002-2003.

Abstract

LQAS techniques proved useful in identifying small health areas with lower vaccination coverage, which helps to target interventions. Monthly review of vaccination coverage by subcenter and village is recommended to identify pockets of unvaccinated children and to maintain uniform high coverage in the PPHC area.
