Who taught you biology they failed you terribly. Viri can be killed. They also can be inhibited from reproduction. The same way an antibiotic inhibits bacterial reproduction and thus ends the infection. Antiviral drugs inhibit the virus ability to reproduce at the cellular level and thus ends the viral replication chain and the ensuring infection. Same effect different mechanisms. Protease inhibitors work by locking the spike protein from invading the cell and the virus they cannot replicate. The drugs that have turned HIV from a 100% killer in to a treatable condition are all PI drugs. Covid has HIV spike proteins how they got there is a matter of debate but fact is they are there. It is no shock and to be expected that protease inhibitors would also work on Covid with the identical spike proteins. It’s not some vast conspiracy it’s just science. Pfizer is testing the equivalent of penicillin for Covid nothing more nothing less. Leave the crap politics aside they have no place in science. Pfizer is testing a solid scientific approach to stopping infection.
Maybe go back and read some of my other posts or the replies to my posts? Please don’t sink to the level of insults. It’s not necessary. I admitted I’m not an expert, but I took AP Bio in HS and passed several college-level biology classes with straight As. I know what I know, I just didn’t express it the same way others have. It’s been over 20 years since I’ve been in a bio lab. Excuse me for being human.
