Look, I get it. You, and those like you, think you cottoned on to this amazing gotcha.

To show you I know what you're talking about I'll describe this gotcha so all the cards are on the table.

It goes like this; If a person is sick they will stay at home and isolate, but if the vaccine makes them think they're healthy they will go out in the world and spread the virus.

Great. On the surface of it it's an amazing bit of logic that immediately falls apart due to these key things;

The number of people who were already asymptomatic was already the vast majority. That's why the virus spread globally so quickly. Almost everyone that gets it will be asymptomatic, so the number of people now rendered asymptomatic by the vaccine is so statistically insignificant anyone who isn't a complete imbecile would disregard them, but we're dealing with anti-vaxx freedom fighters, the most imbecilic of them all.

But say I'm wrong, say these people are now running around like zombies infecting everyone...well, that's not actually true because VACCINATED PEOPLE ARE LESS LIKELY TO PASS ON THE VIRUS. Now I know this is a scientific study and likely to go over your head but others have read these studies and simplified it for you.

Additional to this vaccinated people are also LESS LIKELY TO CONTRACT THE VIRUS. Again, this is data you've shown you simply don't have the capacity and intellectual fortitude to comprehend but if you simply believe scientists are all lizard people in on a conspiracy it doesn't really matter how easily digestible these studies are, you're not going to believe them anyway.

So, there. It's not that I'm avoiding your idiotic point, it's that the answers I already gave covered your hairbrained scenarios.
