The first vaccine was rolled out in 1796. That was over 200 years ago. And we have continued to research vaccines ever since.
The first antivax propaganda started appearing in the early 1800s, over 200 years ago. And many of the claims are still being used in antivax propaganda today.
The fact that the vaccine is only a single mRNA molecule from the virus and not a whole virus means that the vaccine cannot do anything that an actual intact virus can do. Because it takes a whole virus to take over a cell. A single mRNA type can’t do that.
And why should I care about CDC updating the definition of vaccine to better encompass what a vaccine actually is? I’m a scientist. In my work, the majority of vaccines are not used to protect against pathogens at all. They are used to generate antibodies for use in research. A vaccine is simply an antigen which stimulates the immune system to produce T-cells, B-cells, and antibodies. This is exactly what the Covid vaccine does, ergo, it is a real vaccine.
mRNAs weren’t invented until the 1960s and it took a decade to figure out how to introduce it to cells. It is NOT a vaccine or at least a classical one until the CDC to lie about it. You can keep your Covid cult information it’s nothing g but sham government BS AFAIC.
