The question is how do we know what is truth or lies. We can keep our blinkers on and ignore one set of evidence (like this https://www.naturalnews.com/2021-08-08-hhs-documents-admit-the-cdc-has-never-isolated-any-covid-19-virus-global-hoax.html), or we can take them off and not only examine the "evidence" but also who is presenting that evidence.
How do we know? Shit tons of empirical evidence vs flat earth level hearsay, misinformation, and disinformation. It is very easy to find the truth if stop believing conspiracy theories and disinfo like your shared. Natural News (a Conspiracy and Pseudoscience "news" site), not presenting the evidence. The vast majority of the medical world, scientists who specialize in virology and not ones that claim to be "experts" or those who are antivaxxer. Maybe research it and read the actual scientific journals and not the far right propaganda or anti-vax/anti-science disinfo campaign. Where do you find the evidience? All over the place at this point.
OR, maybe like I pointed out in the first place in the OP, go see your medical professional, AKA your doctor. You could go to a vaccination center and ask all the questions in the world. They aren't there to force you to do anything. They will be glad to sort out the myths and lies from the reality and science. Go talk to the countless frontline workers who have seen day after day after day of people going on ventilators or you know...dying. These people have been talking loudly the entire time. The truth is out there and its not on some tin hat site or anti-science web page.
To be clear, dont get it if you dont want to (like I said), but stay home unless you cant, and dont get upset when people ask you to wear a mask around them or inside their business or home. Social distance when you can. And even after the pandemic, wash your hands on a regular basis.
