Vaccine effectiveness against delta variant is less

Researchers from scientists at Oxford University states that the effectiveness of the Vaccines against the delta variant is less protective and rapidly wears off in the months following vaccination. This is almost similar for AstraZeneca, Pfizer, and Moderna, the effectiveness of these vaccines were tested in a group of people against the two most recent dominant strains alpha and delta variants. The Moderna Vaccine appeared to be the most effective against the delta variant after a single shot. Pfizer vaccine was initially strong as Moderna initially but this waned rapidly after 4-5 months.

Dr. Simon Clarke, an associate professor in cellular microbiology at the University of Reading mentioned that the data sets all show how the Delta variant has blunted the effectiveness of both the Pfizer and AstraZeneca jabs but a third booster shot would help vulnerable individuals. Whilst most of the countries haven’t completed full vaccination yet to their citizen America and Britain are planning on a booster shot their people for the third time coming September.

A vaccinated individual could be able to transmit the delta variant similar to unvaccinated individuals.  The discovery of the waning immunity in the Pfizer vaccine requires a booster to work with more efficiency. Despite all these results getting vaccinated is the best way to protect you from Covid-19.
