That is false. There has been an open debate but so much data was being generated that very poor early studies were being touted in the media, and they didn't grasp or present the scientific method. There was also an urgency and a hunger for answers. Sketchy characters and con-artists were spouting off that they had some magic drug, you know, like hydroxychloroquine, but there was real data to support it.
What really happened was that some people were pushing their own magic cures without data (see hydroxychloroqine) and when these "magic" drugs were debunked those who clung to the drugs as magic bullets couldn't handle it. They claimed the data was twisted, or being suppressed as part of some grand conspiracy.
A non-sequitur. It is also false as large companies shut down too. This was an unprecedented pandemic in modern times with hospitals being overwhelmed and no treatment or even tests available. Shutdowns were the prudent move. Still, 1 million Americans died so far or 1 out of every 330 Americans.
There aren't any DNA changes from the vaccines. The mRNA in the mRNA vaccine gets degraded in a short period of time. I don't know what you are reading or viewing but you are being mislead.
