That's interesting. Would you mind providing a link? They say there are still a lot of unknowns about the virus and the vaccine also, how effective it might be, if people might need booster shots in future, should kids be vaccinated, etc.
Two conclusions I've heard, and they may change with time, seem to come up lately: The vaccinations will
reduce the spread of the virus, and although it might not prevent you from getting the virus 100%, it should
prevent you from getting sick or very sick if you do get it.
"What are the benefits of getting a COVID-19 vaccine?
A COVID-19 vaccine might:
- Prevent you from getting COVID-19 or from becoming seriously ill or dying due to COVID-19
- Prevent you from spreading the COVID-19 virus to others
- Add to the number of people in the community who are protected from getting COVID-19 — making it harder for the disease to spread and contributing to herd immunity
- Prevent the COVID-19 virus from spreading and replicating, which allows it to mutate and possibly become more resistant to vaccines
- Can I still get COVID-19 after I’m vaccinated?
COVID-19 vaccination will protect most people from getting sick with COVID-19.
A very small percentage of fully vaccinated people will still get COVID-19 if they are exposed to the COVID-19 virus. These are called vaccine breakthrough cases. Some people might not experience any symptoms and some people could become sick due to COVID-19.
However, vaccination might make illness less severe. If you are fully vaccinated, the overall risk of hospitalization and death due to COVID-19 is much lower than among unvaccinated people with similar risk factors."

The assumptions I draw is that if a person gets the virus either from a vaccinated or un-vaccinated person, that person won't get sick or very sick if vaccinated. If people stop getting sick, the virus should stop spreading. I guess we won't know that for sure, if the virus will eventually shut down or stop spreading fully, until more time goes by.
