There arguments on if the vaccine is safe are naïve at best. There is no such thing as safe (unless you're dead). There are only degrees of safe. Something can be safer than something else, but we are never 100% safe.

If you aren't vaccinated against Covid you're 15-10X more likely to die if you're infected and your chances of long term problems is much greater. If you don't get vaccinated you won't get sick from the vaccination. However it is very likely you will eventually get infected.

So you can take your chances with getting vaccinated or having severe medical problems if you get infected. Nether are for sure and it is up to you to evaluate your chances. Current medical knowledge is that if you go down the path of no vaccination you're taking the (much) higher risk option.

It's you life and your decision to make. However always wear a mask when in public. It isn't to protect you. It is to protect others.
