If people didn't get vaccinated for polio 60-70 years ago, that would still be a huge problem today. Same with mumps, measles, chicken pox, small pox and so many other viruses. And whilst mumps, measles and chicken pox are appearing again, it is because parents are refusing to get their babies and young children vaccinated for these diseases.
The fastest way to defeat a virus is to get vaccinated. If you don't want to be vaccinated, go live a solitary life and never come in contact with another person or animal.
