Studies point to better protection with mixed doses; experts call data ‘fragmentary’
Rath described all this as fragmentary, arguing “that there is no evidence at all about just how much of an increase in antibody levels is actually needed for any extra protection, and how much beyond that makes little difference if any.”
Those who received two doses of Covishield (manufactured by Serum Institute of India) will receive the same vaccine as the third dose. The same goes for Covaxin (manufactured by Bharat Biotech International Ltd) and Sputnik.
Evidence till now accounts for reduced antibodies, but several studies, yet to be peer-reviewed, argue that the immune system’s T cell response remains intact even against omicron. This means that two doses of a vaccine continue to protect us against severe disease.
