Do you think it is possible for scientists to create a vaccine that will in effect disinfect any virus that enters the human body?

anything is possible

There are at least two research lines that I've seen out there that are looking at general virus cures.

A virus isn't really alive. It's just a DNA payload with a protein shell that tricks your own body into making copies. Both lines disrupt the way it tricks you into make more of it.

Both are showing promise enough that I think they get there. It's probably 5-10 years off.

Vaccines don't "disinfect".

Why are you suggesting people put disinfectant into there bodies ? You should be reported to the press so they can draw and quarter you in the realm of public opinion . You are disgusting to tell people to do that . As Greta would say " how dare you "

No, scientist haven't found a vaccine for AIDS in 40 years.

one single vaccine that works against all viruses?

No way

Theoretically,  it's possible to create an environment that will "disinfect" a virus BEFORE it enters the human body.
