Literally expecting vaccines to be 100% effective at preventing the disease is the most wishful thinking anyone has ever had about a medical anything ever
A vaccine is not going to prevent it 100% of the time, and constant or frequent exposure to the virus in question will inevitably lead to infection
Reducing the likelihood of infection will reduce the chances of people getting infected with it, people spreading it, and people getting re-infected with it
It’s why polio disappeared everywhere that was vaccinated for it
If you don’t understand virology you could just say that instead of being extremely wrong

This is literally not understanding virology again
I’m not gonna tell you to take a college course or anything, they literally teach this stuff in first grade

When VACCINATED FOR THE DISEASE you are UNLIKELY to catch it, but if exposed, YOU CAN STILL CATCH IT
When NOT VACCINATED FOR THE DISEASE you are LIKELY to catch it, and if exposed YOU WILL LIKELY CATCH IT
When UNVACCINATED PEOPLE who CATCH THE DISEASE are in general public, EVERYONE CAN STILL CATCH IT, EVEN THOSE WHO ARE VACCINATED
When you are unvaccinated against the disease, you are MORE LIKELY TO CATCH THE DISEASE, and THEREFORE MORE LIKELY TO SPREAD THE DISEASE
The point of widespread vaccination is to PREVENT PEOPLE FROM CATCHING IT, which PREVENTS PEOPLE FROM SPREADING IT
I don’t know how much simpler I can make this, this concept has literally been around for over 200 years
