“It seems to affect younger people more often. In the United Kingdom, studies showed that children and adults under 50 were 2.5 times more likely to become infected....
[note - are young people infected more because most of the elderly in England are vaccinated? or is another dynamic in play?]
.... Studies suggest it might have almost double the risk of hospitalization than the alpha variant.
In China, doctors say patients with the delta variant are sicker than those they treated early in the pandemic....
[note: does this mean fewer asymptomatics?]
...Reports suggest two doses of the Pfizer-BioNTech vaccine provides 79% protection against delta variant infection. It seems to be 88% effective against symptoms if infected.
Two doses of the AstraZeneca vaccine are 92% successful in stopping hospitalization due to the delta variant. And no deaths have been reported among those vaccinated.

Someone posted a few days ago that delta was supposed to be milder but WebMD says no? In England, delta is now 90% of all new cases, I think in something like 3 months; in Los Angeles it’s about half of all new cases. First isolated in India, Dec 2020, now in 74 countries. (which is kind of strange considering all the travel restrictions in so many countries but I digress)
The vaccines were modeled to alpha (wuhan) but pharms say they are able to tweek it to account for mutations, like the delta. I guess that’s where boosters come in for those who didn’t receive the latest and greatest version? Or not.
Wimbledon is on with the stadiums filled and no masks.
