The clinical observations, interesting follow up studies established that of all vaccines, mRNA vaccines, such as the ones developed by Pfizer-BioNtech and Moderna may provide lifelong immunity against coronavirus with its regular dosing schedule.
While the Astrazeneca vaccine has been found to be well-effective against mutant strains and passes the WHO standards of vaccine safety, it mounts a less effective efficacy in comparison to other vaccines and offers fewer protective odds with just a single dose of the vaccine. However, the Oxford study, which has not been published yet, has observed that doling out a third dose of the vaccine offers a much-stronger immune response with vaccination and leads to a ‘substantial’ increase in antibodies which does not compromise immunity.
Interestingly, the study also found that the vaccine also offered similar rates of response and immune protection when the second dose of the vaccine was administered as many as 10 months later. Overall, the researchers have advocated for the administration of a third potential COVID-19 dose.
Apart from this, it has also been studied that the side-effects of the vaccine tend to be more well-tolerated, with lower incidents of side-effects being reported with the second and third vaccine doses.
Could the third dose act like a potential booster dose? Or will the dosing gap be revised again? Here’s what the latest studies have found…
