Honestly, I wouldn't force older people to be vaccinated. Because according to sources I read that the covid-19 vaccine has side effects such as diarrhea and dizziness, and I don't want to harm the people closest to me, especially those who are old.
Of course. You wouldn't want to feel dizzy for a few hours! How barbaric! I know I'd much rather have respiratory failure and a 20% chance of death than feel a bit dizzy. 
If the vaccine is really helping we should all be taking them. It also depends on how much contact you have with others. If you live in a retirement home than the risk of catching corona is much higher than if you live alone.
