A member asked:
Took titers antibody tests 4 months after each of my 4 pfizer vaccines & my internist would inform me that i had no protection left from these vaccines. i had my 5th pfizer bivalent three weeks ago. how can i wait 1 year for #6 w/o protection?
A doctor has provided 1 answer
Immune response to a vaccine involves not only antibodies produced and carried in the blood stream, but also immune memory cells, etc. Even though your antibodies are no longer circulating, you definitely have immune memory cells, etc that are ready and waiting to protect you in case you are exposed to covid-19.
