I am not convinced it will cause full blown aids. Creating a vaccine that does what your immune system normally does, overtime, could cause it to atrophy and unable to function properly with out instruction (another dose of vaccine). Guaranteed repeat customers.
If it were a one-time thing, as with an actual vaccine (e.g. polio), I wouldn’t think too much along those lines. But it looks to be a neverending stream of “boosters” presenting problems.
