Excerpt:

On Monday, July 19, the country is ditching all of its remaining pandemic-related restrictions. People will be able to go to nightclubs, or gather in groups as large as they like. They will not be legally compelled to wear masks at all, and can stop social distancing. The government, with an eye on media coverage, has dubbed it “Freedom Day,” and said the lifting of safety measures will be irreversible. 

At the same time, coronavirus cases are rapidly rising in the UK. It recorded over 50,000 new cases on Friday, and its health minister says that the daily figure of new infections could climb to over 100,000 over the summer.

…..

The UK’s vaccination program is still under way, but it has been broadly successful so far. In all, 68% of the adult population is fully vaccinated, and about 88% of adults have received their first dose (this includes the 68% who have had both doses). Just 6% of Brits are hesitant about getting a shot, according to the Office for National Statistics

…..

But the government seems to be betting that not all numbers are equally scary. It hopes that hospitalizations will stay low enough to stop the National Health Service from being completely overwhelmed. It is making the assumption that the link between cases and hospitalization rates has been weakened, if not broken. 

“This wave is very different to previous ones,” says Oliver Geffen Obregon, an epidemiologist based in the UK, who has worked with the World Health Organization. “The proportion of hospitalization is way lower compared to similar points on the epidemic curve before the vaccination program.”

The Delta variant doubles the risk of hospitalization—but the vaccines still work

Excerpt:

The good news? Vaccines still sharply reduce the risk of being admitted to hospital with the Delta variant. The Scottish study found that the Pfizer/BioNTech vaccine provided 79% protection, two weeks on from the second dose, while the Oxford/AstraZeneca vaccine offered 60% protection. That lower rate may be due to the fact that it takes longer for immunity to develop with the Oxford/AstraZeneca vaccine, researchers said. 

However, research released shortly after by Public Health England was even more promising. It found that the Pfizer/BioNTech vaccine provides 96% protection from hospitalization after two doses, while the Oxford/AstraZeneca is 92% effective at preventing hospitalization after both shots. The conclusion? It’s yet more evidence of the importance of making sure as many people as possible get vaccinated, and that they get both shots.
