It met the standard applied to it by the FDA. They released the drug with a heavily watered-down testing protocol because of "an emergency". As long as the drug companies followed the protocol set up by the FDA ... even if that protocol was crap ... they are off the hook.
You can try to go after the FDA for knowingly instituting a negligently insufficient testing protocol, but you won't win.
And let's be fair here ... none of the drug companies making vaccines claimed the vaccine would lessen your chances of either catching or passing the virus. That claim was being pushed by government and media pundits. The only claim made by drug companies was that they had some clinical evidence it might lessen the severity of the symptoms.
If you dared question why the drug was so necessary if the drug companies weren't saying it would prevent the spread then you were labeled an "anti-science conspiracy theorist" and banned from Facebook for spreading misinformation.
Don't get me wrong, this whole COVID thing was a colossal frak up from day one. The media scared everyone into demanding the government do something, The government, having nothing useful to do, did every thing they could think of regardless of the harm it might do, and we, the voters, went along with it because we were all terrified by the media.
Now that the fear has subsided, it's like waking up on the floor of a frat house with your panties around you ankles. You want to know what happened but, deep down, you know you probably made a lot of bad decisions last night.
