The fact that people this stupid exist

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

There have been recent breakthroughs in that area along this exact line of thought, actually.

PreP is a really effective tool for now while research continues. Your chances of getting HIV while taking the medication correctly reduces your chances to a very very small percentage. Of course, nothing is perfect, but it's been great for the gay amab community.

They are, but every time they get close to a cure god sends a hurricane to destroy the lab and kill all the atheists inside it
