Here’s How Long Moderna Vaccine Immunity Will Last
New York: American firm Moderna’s COVID-19 vaccine will cause the immune system to produce antibodies that will last at least 3 months, AFP reported.
However, experts believe that if antibodies fade over time, our immune system may remember and form new antibodies if exposed again. This will be verified in a longer study.
The vaccine that has been claimed to have an efficacy of 94 per cent showed that antibodies “declined slightly over time, as expected, but remained elevated in all participants 3 months after the booster vaccination”. The study was carried out by the National Institute for Allergies and Infectious Diseases (NIAID) and done on 34 adult volunteers.
The vaccine is administered in 2 shots four weeks apart.
Moderna is expected to get an emergency approval from the Food and Drug Administration (FDA) on December 17.
Moderna is slightly behind Pfizer and its German partner BioNTech, which has received approval in the UK.
