You do know that the developer of the AstraZeneca shots himself stated in august 2020 that these shots cannot achieve herd immunity because they allow infection and transmission and are merely a potential severe symptom mitigator which wane drastically in 3-6 months? He even warned policy makers to not make policies based on achieving herd immunity from these shots.

Viral load is the same between vaccinated vs unvaccinated folks as shown by several studies now. In many cases, it’s even higher in vaccinated folks.
When a shot doesn’t prevent infection, that also means it allows mutations to occur in the vaccinated person which created immune escape variants more likely.
You are conflating these shots with more traditional shots. The purpose of those traditional vaccines are to PREVENT infection and transmission. Smallpox, polio, measles etc vaccines all stop infection and transmission.
Also those vaccines are long term tested for many decades. Smallpox vaccines are 200 years old.
Smallpox, polio, measles etc also have severe problems to the person who gets them including kids.
The COVID shots neither prevent infection and transmission, not have they been long term tested. And COVID is negligible for kids and youth unless you are obese or have pre-existing conditions (in which case, the COVID shots also aren't much effective).
These shots should never have been called a “vaccine” because they do it fit the definition of a vaccine as they don’t prevent infection. Legal definition of a vaccine is:
> The term “vaccine” means any substance designed to be administered to a human being for the prevention of 1 or more diseases.
Notice the word “prevention”. Covid shots don’t do that.
