Variable delta doubles the risk of hospitalization – but vaccines still work

The good news? Vaccines still significantly reduce the risk of hospitalization with the delta variant. The Scottish study found that the Pfizer/BioNTech vaccine offers 79% protection, two weeks after the second dose, while the Oxford/AstraZeneca vaccine offers 60% protection. This lower rate may be due to the fact that it takes longer to develop immunity with the Oxford/AstraZeneca vaccine, the researchers said.

However, search Released shortly after by Public Health England It was more promising. It found that the Pfizer/BioNTech vaccine offered a 96% protection against hospitalization after two doses, while the Oxford/AstraZeneca vaccine was 92% effective in preventing hospitalization after both injections. conclusion? It is further evidence of the importance of making sure as many people as possible receive, and that they get both injections.

intended: The delta variant is 64% more transmissible than the alpha variant indoors, according to Public Health England.

This data, along with hospital admissions data, is why the UK has delayed plans to lift most remaining covid-19 restrictions by a month. The hope is that those additional few weeks will provide enough time for the number of fully vaccinated adults to increase. Although more than 70% of the UK adult population has taken a single dose, just over half have taken a single dose.

The great fear: One concern, from the beginning of vaccination programs, has been that current vaccines will become much less effective as the virus evolves and adapts, a scenario known as Vaccine escape. As it stands, this does not appear to have happened. But eventually we will need new vaccines designed to address variants more precisely.
