That is why the genetic sequence is mutated in HIV. The infectiousness of HIV is thought to be mandated by the gp130, the main protein that binds the CD4+ cells--apparently at the TCR for T-cells or APC binding site in Macrophages.

And children's immunity is boosted upon injection. It is different when the ACTUAL vaccination agent is causing the problem (which is highly unlikely) and the nonactive ingredients, such as over-sulfated chondroitin--which causes more problems than needed.

I agree, as far as we know, they don't have immune systems but they are living. The problem with HIV is it mutates more rapidly than other viruses, which makes it one of the biggest obstacles to a successful vaccine. One thing about it though, is it's genetic material is prone to errors during duplication and replicating HIV molecules frequently exchange pieces of genes. Because of this, instability and the potentially rapid life cycle of the virus, the genetic sequences of HIV particles in a single person can actually be as diverse as those of all the influenza viruses worldwide. You have to remember, a vaccine that produces an immune response against one HIV sequence may have no effect on other strands.

What would be great if there were one vaccine that contained ingredients to prevent or slow down all viruses. I know in animals there are some medications that can be prescribed for a certain parasite, while at the same time preventing others. Like Epsiprantel for example has no effect on ascarids or hookworms, but it kills tapeworms. On the other hand Fenbendazole is good for getting rid of ascarids, hookworms, and tapeworms and also works great for treating giardia. Milbemycin oxime treats all the parasites I've listed but has no effect on tapeworms, but works great at killing heartworms. But even the medications that work great at treating more than what they're prescribed to treat, still do not treat everything.
