Recent studies have indicated that the Oxford-Astrazeneca COVID-19 vaccine is well-effective against the Delta COVID-19 variant.

Now, newer studies have indicated that further spacing out the vaccine doses, or allowing people to get a 'third' dose at least 10 months after the second dose will lead to an enhanced immune response.

The Oxford-Astrazeneca vaccine has been found to be well-effective against mutant strains. Overall, the researchers have advocated for the administration of a third potential COVID-19 dose of AstraZeneca vaccine.

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.

The findings of the Oxford study are yet to be reviewed or published in a scientific journal.
