The COVID vaccines are not seeing a large number of breakthrough infections, chance of a breakthrough is estimated at between 1/5000 and 1/10,000 in the most recent estimates.

 

The virus most nearly similar to COVID is the flu. 

Both are respiratory viruses and are spread in similar ways.

Both mutate frequently.

Flu requires a new vaccination each year even after years of research.

 

There is no reason to believe that anyone will need a booster every six months.

That is quite an extrapolation when there has not yet been a booster.

 

Other vaccines require multiple inoculations.

HepA 2 shots, 10 years.

HepB 2, 3, or 4 shots and 10 years efficacy, possibly more with full series.

Polio 4 shots are recommended.

Tetanus 1 shot, lasts 10 years.

Zoster 2 shots, lifetime ?

 So 2nd and 3rd shots are not rare, and we don't know how long protection may last after a 3rd COVID shot.

How many shots do you need for covid to be fully inoculated and how long does it last?

Usually those are answered during the development of vaccines and can be answered confidently before sending out the vaccine for millions.  Many people would like to know that answer before doing anything.

"Usually those are answered during the development of vaccines and can be answered confidently before sending out the vaccine for millions."

I don't think this has ever been true,  Nothing like the way the polio vaccine was brought to the public.

You make statements as if you knew something about vaccine development but your last post indicates otherwise.

 

"Many people would like to know that answer before doing anything."

Fewer all the time especially where COVID is surging.
