two more vaccines are coming onto the market - Johnson & Johnson, which I believe is just one shot, not two, and the Astra Zeneca.
I'm hoping that by June anyone that wants a shot can get one.
It is my understanding that both these are viral vector vaccines. Which means they deliver DNA into your nucleus. They use a carrier virus to do that. The DNA then causes your cells to produce mRNA which in turn produces antigens.
Moderna and Pfizer are both mRNA vaccines which use an LNP as the delivery vehicle to get the mRNA into the cells. These skip the DNA part and just induce your cells to produce antigens.
Do your research folks. I don't know, but I don't want foreign DNA in the nucleus of my cells. Which cells are targeted by the vector virus? How long does the DNA stay in the nucleus? All questions I don't know.
