The yellow card system for monitoring side effects has also been running for nearly two years now.
Two years for the covid jab, much longer than that for other vaccinations and medicines.
If you don't want to be jabbed then you will always be able to find a reason to avoid it. If you are happy to take your chances with the virus then that's your choice.
If there choice, only affected themselves alone, then fair enough - except it doesn't, we all pay the price of their bad decisions.
