I’m not trying to shit on your parade but that article doesn’t address the efficacy of the COVID vaccine. It just addresses the delivery method progression of mRNA vaccines and how it was utilized for the COVID vaccine. I think many of us can easily agree that vaccines have been beneficial overall and saved lives. It’s troublesome to claim that the COVID vaccine was effective, safe and absolutely necessary.
The article says: "With COVID, this technology got its moment and has proven to be extremely safe and effective."
You can google and find things saying any medicine and vaccine is unsafe if you wanted. There is going to be some grifter out there that will post lies. It's amusing how quickly people suddenly became medical experts during COVID. I think many here have let your brains be rotted out by social media and it's sad.
