    Yes, they are working diligently to ID an effective mRNA vaccine, but the same barriers exist as before. First, HIV mutates rapidly, meaning it easily escapes immunity and evades vaccines. Second, as a retrovirus, it integrates its DNA into a person’s own cellular DNA, so even if your immune system destroys the virus, the DNA remains undetectable to the immune system and able to manufacture new virus at will.

    (Responding to the picture here) As for cancer, it’s not a virus or bacteria, which is what vaccines have typically worked against. Cancer is your immune system failing to kill a cell from your own body that has mutated to grow out of control. They’re rapidly developing mRNA techniques for cancer, too.

    COVID was a fucking walk in the park immunologically compared to cancer and HIV

      Yeah, retroviruses are a hard nut to crack. Either you try to target the virus and leave the cells alone, which is the hard route, or you target the specific DNA sequence of the virus, which forces the body to start murdering itself.
