"Share protection" is not a thing. Why would anyone try to do that, unless there is a desperate shortage? The vaccine is designed to be administered it two shots, not one. I do not know if it is 33% after one shot, but after the booster it is 95% efficient. So, what is your point? Why are you telling us that it does not work well before it is fully administered? Obviously it does not work as well, because if it did, they would not give a second dose.
Your objection makes no sense!!!
What other nonsensical complaints do you have? It also does not work the day after you get the first shot. It doesn't work a week before you get it. It does not work when you watch someone else get it; "share protection by proxy" does not work.
There is talk that the biden administration will release the vaccine stockpile, now being saved for booster, trying to get as many as possible with one jab, banking on vaccine manufacturing to meet very tight goals. I posted my concerns with this policy as this virus will take advantage through mutation to evade the vaccine coding. It has done this already with treatments. We are not dealing with the average virus. This one throws convincing counterpunches
