You were telling people to report side effects despite the fact that the more common side effects are already clearly documented on sheets supplied with medicines, why?
Because new medicines are subject to being 'black triangle' drugs for maybe a couple of years after launch. During this period
all side effects should be reported. Then the data sheets are amended accordingly when more and more information is known, and changes made. It's the rarer ones which generally take a while to show up because, guess what? They are rarer.
So in trials a numb arm, sweaty and maybe a rash are shown. These go down as common side effects, in a group of maybe a few thousand, or sometimes just a few hundred people. If you stopped listing side effects at that point, then no new ones 'would be allowed' as it were. Now the AZ has been given to 10s of millions of people worldwide, new side effects are emerging. If no-one reported the blood clots then where would be?
One of the drugs that showed great efficacy and a vanishingly small side effect profile in early trials was of course thalidomide. When it was launched and given to all expectant mothers who were sick, look what happened.
