The above is pretty important.
So the vaccine will get us back to normal? Once 100% get the shot and the boosters every six months till the overlap is at 100%?
The vaccine is effective after 6 months. The reason for the booster is to insure longer term full effectiveness. We might need another booster only time will tell. As the virus mutates it is likely at least a variant of the current vaccine will be necessary, just as is the case with the flu vaccine that is modified, hopefully correctly projecting what mutation the virus will make annually. Most of the small percent of crossover cases were COVID 19 cases. COVID 19 has a much higher infection rate and was not in existence when the vaccine became available. While the vaccine is effective against the variant, because of the high infection rate of the Delta mutation, maintaining a maximum level has become more important.

Since the effectiveness has shown to be less and the percentage of breakthrough cases in the non-familial study I posted hit such a huge percentage..... let's just say it doesn't look effective compared to the claims.

Again, I can't get to the study. What is the source of the study.? What I have read from infectious disease experts is there is insufficient evidence to draw an iron clad conclusion and that current studies have shown the percentage of breakthrough cases to be very low. In addition, the symptoms are not as severe for those that have been vaccinated, and only .01% required hospitalization.

Why is it that antibodies from previous infection is totally discounted, when it has shown to have a stronger and broader response?
The same is true of antibody testing. Not enough information to draw a firm conclusion. The current recommendation is to get vaccinated even if you have had the virus. One scientific study recorded only 11% of those tested showed evidence of antibodies.

The recommendations of the CDC and WHO have been revised as studies learned more. It is easy to view that as they don't know what they are doing. In April they said xxx and now they are saying yyy. That is because the virus was completely new and later mutated. As more was learned the most effective treatment and protection required revision.
