So, you are backing away from your claim that the vaccines in your list are adenovirus vector vaccines or mRNA vaccines.

These 2 types, in particular, trick the patient’s cells into expressing viral genes, and they are new, and in my view experimental.

Nice “ spinning “

——Wow——

"your claim that the vaccines in your list are adenovirus vector vaccines or mRNA vaccines."

Strawman; I never made any such claim. They're generation 2 vaccines. Gen 1 vaccines are those based on live attenuated or inactivated pathogens. Gen 2 vaccines include the subunit, recombinant, polysaccharide, and conjugate vaccines, which is what the Johnson&Johnson and Oxford/AstraZeneca vaccines are. The second generation vaccines date back to the late 70s with the first recombinant vaccine approved in 1986.

When speaking of viral vectors specifically, work began on them in the 1970s. There are 7 different commonly used viral vectors, each with its own distinct advantages and disadvantages. Recombinant versions of the vaccinia virus used in experimental herpes treatments date back to 1982 and utilized the viral vector method. The first clinical trial of a therapeutic retroviral vector took place in 1990.

So no, this is not "new".
