Covid-19 vaccine still best way to protect oneself from Delta Variant

It is being claimed that taking both the doses of Covid-19 vaccine can still be the best way of protection against delta virus variant. This test result was first identified in India and now inthe United Kingdom as well. Further studies show that the Oxford-AstraZeneca jabs, although less effective, but does offer the same level of protection as provided by Pfizer-BioNTech after four to five months, which was known in the largest study of its kind. But these vaccines are not as effective as they were against the Alpha variant, which caused most of the infection in the UK last winter. Although not much data is available for Moderna, researchersbelieve it is equally effective as the other vaccines. 

The analysis for the effectiveness of these vaccines was done based on half-million test results from a total of 743,526 participants in the UK’s Covid-19 household infection survey led by Oxford University and the Office for National Statistics.

As per the data received, the Pfizer-BioNTech vaccine had 93% effectiveness against the Covid-19 infection symptoms, two weeks after taking the second dose, whereas Oxford-AstraZeneca’s vaccine has its effectiveness up to 71%.
