This issue is, appropriately, contentious. As a vaccinologist - & citizen & relative of people in at-risk groups - I fully support the UK decision to increase dose intervals of both our Ox/AZ product and the Pfizer product. I'd happily receive either with a >8w gap. Here's why 🧵


For the Ox/AZ vaccine, it's fairly simple. The trial demonstrated efficacy at a range of dose intervals. Antibody responses after the boost were significantly stronger with longer intervals - see table

(so in response to @drmarkporter's point, higher immune responses with a longer interval is proven & now public. I haven't seen a similar analysis for efficacy against disease but the data exists and I suspect the regulators & JCVI committee have)

For Pfizer, there isn't direct evidence of efficacy with a >3wk interval. But as widely publicised, efficacy in the period from 14 days after first dose to 21 days is high.


Can we extrapolate from this to a longer interval? It's a judgment call. On one hand is evidence-based medicine's scepticism of anything not directly proven 'beyond reasonable doubt' in an RCT; on the other is a 'balance of probabilities' approach based upon the biology.
Wow, so here we are, 36 hours after the destruction wrought on DC and this thing we call “democracy”... “The American Experience”. We’ve all seen the pictures and heard the gaslighting by a group that has no moral compass. We *have* been here before, and it’s time to get out. 1/

First, some history that some are likely to remember. Does anyone remember The Vandals? Not the band, but the actual tribe of Germanic people who were pushed around Europe when it was the Roman empire. Maybe worth a read:

As you might imagine, these people weren’t the brightest bulbs in the box or one of them would have built an electric car that you actually wanted to drive. Or just simply proclaimed that the earth was not flat and revolved around the sun. 3/

Any student of history will tell you that it repeats itself. We call what happened in DC “domestic terrorism”, but when I was a kid, this would have been called “felony vandalism”.

We’ve been here before. That link again in case you missed it: https://t.co/N7zRAeAgq6 4/

If you’re like me, you’re pretty pissed off at having wasted 12 years with modern-day Vandals destroying the change we could believe in and almost destroying the entire American experiment. If it weren’t for COVID, most still wouldn’t notice. But here we are. 5/
I think this thread came from a good place, but I want to add a few thoughts because I think service members WILL be talking about yesterday's events -- and that leaders SHOULD be talking to their troops about them.

They need to be thoughtful, not scared of doing so. 1/


Yesterday, our nation's capital was attacked and the capitol was briefly occupied. 1100 members of the DC National Guard were activated, as were more than 6000 NG troops from half a dozen states.

They're now operating in a highly political environment. More could join them. 2/

Calls for our military to remain apolitical really mean: (1) our military must be non-partisan; (2) it should not interfere or influence elections; & (3) service members should not portray their personal opinions as the military institution's opinions. 3/

While there is a lot we don't know, there are indications that at least some police yesterday acted in a biased way -- allowing the mobs to bypass barriers to attack and enter the capitol building.

Personal/partisan sympathies cannot interfere with a military unit's duties. 4/

Leaders and commanders should talk to their formations about these issues, and try to understand if there are service members for whom that might be a problem. (Hint: there probably are.)

You can't do that if you're not communicating with them and having real discussions. 5/
The @AlphabetWorkers have formed what is called a "minority union." Quick thread on what that means:

A cornerstone of US labor law is the principle of "exclusive representation" - if you collect authorization cards from the employees and win an election, you...

1/


...get to represent all the employees you sought to represent. As the exclusive rep, the employer has to work with that union and that union only on any issue of wages, hours, terms and conditions of employment. In turn, the union has a legal Duty of Fair Representation (DFR)

2/

... to not discriminate against the people it represents if they choose not to join the union.

The big problem: labor law is so weak in the US, employers violate it all the time with no consequences, and therefore obtaining exclusive rep status is really hard.

3/

However, a legal theory floated by law professor Charles Morris in his 2005 book, The Blue Eagle at Work, suggests that the law also allows unions WITHOUT exclusive representation.

3a/

The National Labor Relations Act, after all, in its vitally-important Section 7, says workers have the right to collectively bargain. It doesn't say that right only exists when there is an exclusive representative.
