It's fascinating that you dare say that given that I my content completely disproves your BS when I mentioned the BioNTech vaccine in the same paragraph.
This kind of sick narrative is exactly what made Trumps following grow so much. You are the two sides of the exact same coin that led to the hundreds of thousands of dead in the US.
"This platelet loss induced by Ad5 corresponded with increases in coagulation D-dimer levels, splenomegaly, and, later, production of megakaryocytes in the bone marrow. In contrast, these responses were blunted or ablated after injection of Ad-PEG. Ad5 activated both platelets and endothelial cells directly in vitro as evidenced by induction of P-selectin and the formation of von Willebrand factor-platelet strings and in vivo as evidenced by the induction of E-selectin messenger RNA"
> Adenovirus vaccines are extremely common
I believe you may be confusing adenovirus vaccines and vaccines that use adenovisues as vectors. The former protects against adenovirus infection, the later uses an adenovirus as a vector to vaccinate against some other virus.
There is a sort of common adenovirus vaccine [1].
Adenovirus as a vector is new. There is an adenovirus vector Ebola virus that is approved. I think that is the only one. The only others deployed are for COVID under emergency use authorizations. There are several for other diseases in development, but the farthest along are still in clinical trials.
