Prof. Dr. Agam Vora, Chest Physician, Vora Clinic Mumbai shares, “While the SARS-CoV-2 virus is still around, with stepped up vaccinations, people are returning to work, schools and regaining some semblance of normalcy. Of course there are constant conversations on the status of immunity once vaccination doses are completed. Immunity levels can be determined by antibody testing after at least 14 days of the second dose. It’s also important to talk about the need for a booster dose, and work is going on around this aspect as well. While vaccines are effective at preventing severe infection and mortality, they are not 100 per cent effective in stopping acquisition or the transmission of the virus, more so with waning immunity over a period of time. Testing for antibody levels may help understand the immune status of your body which in turn may help determine the need for a booster dose, especially in the more vulnerable or at risk populations.”
