Today's vaccines/boosters are worth getting because they reduce the chance of hospitalization and death, but that's it. They don't prevent infection.
New vaccines are being researched now. There is hope, but we must be patient.
In the meantime, mask! Avoid getting reinfected with Covid. Repeated infections can do long-term damage. Even mild cases can cause brain and cardiac damage.
