Large-scale vaccination rounds help rapidly boost immunity

The Global Polio Eradication Initiative assists countries in carrying out surveillance for polio and large-scale vaccination rounds. When India was still polio-endemic, there were 640 000 vaccination booths, 2.3 million vaccinators, 200 million doses of vaccine, 6.3 million ice packs, 191 million homes visited and 172 million children immunized: all this in just one round of the national immunization days.
