> the vaccines are not great at stopping the spread of delta
that's not an accurate take on how the vaccines work against delta.
the vaccine makes it so you are much less likely to get the virus in the first place. it also shortens the time you are infectious to other people if you do get a breakthrough case since your bodies immune system response goes into effect immediately and not after a while. an extremely simplified view is: antibodies neutralize free floating viral particles(antigens). B cells create antibodies. T cells tell B cells to go make antibodies and also kill infected cells with cytotoxins.
when you are vaccinated your T cells and B cells already know what to do if they see viruses so they can mount a defense immediately and it shortens the infectious period. in addition you will still have antibodies left over(i am unsure if you still make more for a period of time after the vaccine without any antigens) from when you got the vaccine so you will have a lower likelihood of getting sick in the first place since the antibodies can neutralize the antigens before they have a chance to infect too many cells and create more antigens.
by the nature of not getting sick in the first place and by not being infectious for as long the spread of delta is slowed
