You cannot catch a virus if you received a VACCINE for that virus. This is due to VACCINES giving lifetime IMMUNITY to the virus.
What is being push around is best described as GENE THERAPY.
and considering how none of them have gained FDA approved, the best description is...
EXPERIMENTAL gene therapy
Exactly thats what it is experimental gene therapy.And the stuff they are pushing had 3-4 months of testing instead of the usual 15 years. So where would you put your trust in the old flu vaccine which we know works or the new 3-4 month gene therapy.?
