What precisely happens during a 'National Immunization Day' (NID)? This video-diary of a recent NID conducted in India gives a basic snap-shot of the campaign.

After just six days:
-167 million children immunized
-2.5 million vaccinators
-200 million doses of vaccine
-191 million homes visited

Thanks to India's strong and ongoing commitment to polio eradication, the disease could soon be assigned to the history books. No child need ever again know the pain associated with polio-paralysis.
