I think the issue with the COVID one is that people rushed the tool so its like trying to rake up leaves but you only got two prongs on your rake, that rake isn't going to be very effective in the job you are trying to do. Vaccines are a good thing, rabies for example without it you would die a very horrible death, but at the same time if its rushed or if they do improper studies and harm people from it then you have a person using the tool wrong or just a broken tool.
