No drugs are 100% safe,the pandemic was a once in a lifetime event (hopefully),hundreds of thousands of people were dying, something had to be done quickly.
As a result a tiny number of people have got ill or even died as a result of the vaccine, this will happen with any new drug, however how many millions of lives have been saved as a result of the vaccine ?
If the vaccine has made you I'll, that's very sad,but for the overwhelming majority of people on earth it was a positive thing to do.
