That's already how it works. The overwhelming majority of children in first-world countries are given a slate of vaccinations as a matter of course. Or did you think that polio went away on its own?
Please don't spread misinformation about one of the most successful vaccination campaigns that saved thousands of people per year from being crippled or dead. And especially not during another pandemic in which there already is enough misinformation about vaccines.
From what I see, the situation is the same in India - hardly any vaccination and the big 'C' cases have gone down significantly.
