I think he means to say, Dr Harsh Vardhan is a leader of a major political party. Polio eradication in India was made possible by so many people one can't really thank them all by name. There are so many volunteers, who have worked on weekends going door to door to educate the parents and deliver the vaccination and they have done it over the years. There are doctors, nurses, government workers, even Bollywood actors who've done ads for free to spread awareness. So you can't really thank one person, one government or one organization. This was a national movement which succeeded.
