There is a very cogent reason for forcing everyone to get vaccinated and that is, building what is known as "herd immunity". Only when a high percentage of the population is protected through vaccination against a virus or bacteria, it makes it difficult for a disease to spread because there are so few susceptible people left to infect.

That is how polio was combatted in India and even the most illiterate person here knows the importance of getting the required vaccines, on time. Let me explain, say I contracted the polio virus somehow, and while being sick I met a 100 people, chances are that 99 of them are already vaccinated. That means, at most 1 other person can fall sick because of me and the disease eventually will die, because that person may not come in contact with any more unvaccinated persons. Now if the polio vaccination was a choice, let's assume 40 of them chose not to get vaccinated. I can now infect 40 more people, who will further infect more people like them.

If the herd immunity goes down, epidemics become a very real possibility. And social responsibility demands us to get our required inoculations on time, to protect those around us, who for legitimate reasons cannot get vaccinated, like newborns, or those with compromised immune systems.

Vaccines save lives, and that is a fact. So please get your kids inoculated, if not for yourself, then for those who will come into his life.
