My grandparents were never vaccinated. Alhamdolillah they did not have any side effects. In fact they all lived to a very old age and were mashallah very healthy in their middle age and beyond. I still have a grandmother in india who is very old but more healthier then a lot of people younger than her.

The reasons why your grandparents (and mine) have done well without vaccinations could be many; they could have lived healthier loifetsyles (in terms of food and exercise), they may perhaps never have come into contact with the illnesses/diseases that vaccines are meant to fight away, etc. On this basis, you could never come to a conclusion that people without vaccines would live a healthier lifestyle because there is more than one factor to take into consideration. The best thing is to test in controlled conditions
