How long do the antibodies protect you from COVID-19?
Nobody knows if there is a certain level of antibody, or certain types of antibodies (such as neutralizing antibodies) that can predict protection, although antibody levels are used in clinical trials as a way to estimate protection from the vaccines. Antibody levels indicate some immune response to the vaccine. Some studies suggest that at least for the same variant, protection after infection may last for months, but it’s not certain. Some people who get COVID-19 do get it again even after developing antibodies, so protection is not guaranteed.
That’s why we encourage all Idahoans to consider getting vaccinated and boosted. It’s the best protection we have against serious illness and death.Continue reading “COVID-19 Q&A: Antibodies and natural immunity are difficult to measure”
