At a function to celebrate "India's Victory Over Polio", he said it was indeed a day of celebration and proved once again that "if we work together unitedly and with commitment, nothing is impossible".
"It is necessary for us to remain ever alert and watchful. Our people would continue to be at risk of re-infection till the whole world is fully free of the polio virus," he said, adding that we must now strive to create a polio free world.
Mukherjee also remembered former prime minister Rajiv Gandhi as a "young and visionary" PM who had sought to make India free of polio when nobody thought it would be possible.
He said India's success against polio is indeed a milestone towards universal health care in the country. It proves the efficacy of the innovative tools and strategies applied by the government for the prevention and treatment of the communicable and non-communicable diseases, he said.
"India has demonstrated that despite all the constraints faced by health authorities in a populous and very large developing nation like India, eradication of diseases like polio is possible," he said.
