'covid-19' is a disease not a micro-organism. That would be the presumed 'SARS-CoV-2' virus. Don't you remember your own propaganda bullshit phraseology?
Now, when the (not a) vaccine does not actually stop one from getting the viral infection and does not stop one from spreading it to others, we see why they were so 'Miss Gramerly' on the disease/virus distinction thing from the start. They knew they were going to have to sell a 'vaccine' against a set of symptoms and not against a virus.
