you mean like the chinaflu
Actually I meant the opposite. Since the Covid vaccine is only good for a number of months, not years, and changes form in the way flu viruses do, there is money to be made on the vaccine every year or even several times a year. On the other hand they may have figured one AIDS vaccine shot might be good for years or decades. In that case there was far more profit selling multiple medications daily for a lifetime, thus a good reason to NOT develop an AIDS vaccine if you were a profit driven monster.
