The Pfizer vaccine appears to be just 64% effective at preventing both Delta variant infection *and symptomatic Covid-19*. However, it still appears to be 93% effective against serious disease and hospitalisation. This just announced by Israel's Health Ministry.
These numbers for symptomatic infection are lower than seen in other countries. I wonder if that's because Israel vaccinated more people earlier, and the very high level of sterilising antibodies has waned a little.
I mused about this in April. If this is right, then the UK, with its longer dosing interval, might see a higher vaccine effectiveness against Delta?
Bottom line is that the vaccines are still preventing serious disease and death, as these graphs from the UK show. But it seems like vaccine-induced herd immunity isn't on the cards any time soon.

There's an odd history of early 20th Century feminist pioneers becoming leaders in the fascist movement. Violette Morris is one example.
Rotha Lintorn-Orman founded the British Fascists in 1923, which was Britain's first fascist movement. Mosley's British Union of Fascists was formed partly by breakaway elements from her group
Suffragette Mary Richardson famously slashed Diego Velázquez's painting, the Rokeby Venus, to draw attention to women's right to vote. She became organiser for the Women's Section of the British Union of Fascists.

Daily case numbers in Israel make it LOOK like natural past infection is providing better protection against Delta-variant infection in Israel than vaccination. 9% of the population is recovered. There could be confounders in the data, especially around age profile of cases.
Israel mostly hasn't vaccinated people who recovered from Covid (they could choose to get one dose but it wasn't recommended).
The equivalent graph of daily TESTS shows some under-testing of recovered people (green), but they're running a much lower positivity than everyone else, just 0.1% yesterday

The GhostEzra account first appeared on Twitter on December 27 2020. By Jan 6, it already had 18.7k followers. When it was deleted in the big post-insurrection ban-wave of Jan 8, it had accumulated 31.1k followers in just twelve days. ImageImageImage
How did a new account grow so quickly? It was one of a series of Twitter accounts pretending to be Ezra Cohen-Watnick @EzraACohen, who many QAnon adherents believed to be Q. Note how GhostEzra's avatar was the logo of the DCS, where the real Ezra served. ImageImage
The most well-known of these impersonators was EyetheSpy or E, who in turn spawned their own impersonators. A bunch of Twitter accounts claiming to be E were banned thanks to the real @EzraACohen and his lawyer @MarkSZaidEsq, but E believers were always looking for the next one.

Wow. US moving against Iranian state-controlled media today.
These images say that the US has seized the domain names. But I am able to access one of the sites at its supposedly-seized name (alalamtv.net) which has been repointed. It looks like the US Govt actually just seized the sites at the host level.
If I am correct about this, the sites will probably be back pretty quickly.

British people are rightly laughing at this story that confuses the Rugby position "hooker" with the American slang term for a prostitute. But it's actually an example of how certain parasitic "news" sites do business. Image
The Tom Youngs story is stolen from @SkySportsNews. To avoid automated copyright takedowns, the para-sites steal it but change a few words out for synonyms. Compare: skysports.com/rugby-union/ne… ImageImage
Compare these few paragraphs in the Sky Sports story with the Insider Voice version. It's straight-up plagiarism, with the occasional changing the order of a phrase or substituting a word. ImageImage

In an hour, a "flag march" through Jerusalem will begin. The march was scheduled for last week but delayed until today after police and security services objected to the route.
There is a march of Israeli flags every Jerusalem Day, which marks the reunification of the city under Israeli rule after the Six Day War. That march, mostly of national-religious youths (men and women separated) goes through the Old City to the Western Wall.
What makes the march controversial is that the men march through the Muslim Quarter of the Old City. Shops are closed and sometimes racist slogans are chanted by some marchers — though the event is once a year and usually not marked by physical violence.
