We do?
Initial reports were that the mRNA vaccines were 90-95% effective at preventing infection. More recent (real world) data seem largely consistent.
Here is a summary article:
https://www.nature.com/articles/d41586-021-01505-x
A nationwide vaccination campaign in Israel found the Pfizer–BioNTech vaccine, co-developed by Pfizer in New York City and BioNTech in Mainz, Germany, to be 95% effective against SARS-CoV-2 infection seven days or more after the second dose3.
Data are reported here:

I haven't kept up with the literature on this so 5-10% might not be exactly correct. But it is true that some vaccinated individuals will contract the virus. The good news has always been that this small population will experience much milder symptoms than the un-vaccinated population.
