PHE have published a vaccine surveillance report.

Key chart here (colours represent level of confidence in the numbers, not effectiveness)

- Vaccines work (very high level of effectiveness)
- 2 doses better than one
- They're not perfect
Will be good to see effectiveness of 2nd dose of Oxford/AZ when the data is available, and the effectiveness of different vaccines against variants.
Here are the risk communication charts for:
1 dose of either (Pfizer/BioNTech or Oxford/AZ) vaccine
- 2 doses of Pfizer/BioNTech
Great vaccine uptake
Effect on deaths
"PHE estimates to 25 April 2021 based on the direct effect of vaccination and vaccine coverage rates, are that that 9,900 deaths were averted in individuals aged 80 years and older, 1,500 in individuals aged 70 to 79 and 300 in individuals aged 60 to 69 years ...
"... giving a total of 11,700 deaths averted in individuals aged 60 years or older in England"

Excellent. Please get vaccinated and please get your second dose.

The UK Covid Public Inquiry has published its first Report, on Resilience and Preparedness. It is the most urgent report, as we are still ill-prepared for the next pandemic.

🧵
This is the first of many reports, each reviewing a specific area, including healthcare systems; test, trace, and isolate; and the economic response to the pandemic.

The Module 1 Report sets out nine significant flaws from the Covid-19 pandemic: Image
The Report suggests 10 recommendations: Image

Covid data presentation for the @IndependentSage briefing on 21 April 2023 🧵 Image
Testing has changed from 1 April 2023, so it is difficult to compare before and after this date.

The ONS survey has been 'paused', so we can look at the (less recent, less representative) data on PCR positivity

Alright. Another maths thread. And why it's non-trivial to ask exam questions.
🧵
OK. So the 'exam question' is:

"Inflation is currently 10%. If inflation halves, how much will a £1 pint of milk cost".

Sounds easy. It's not. It's ambiguous. It's not a good question. Unless it's designed to be a bad question. In which case it's a good question.
1. It talks about 'inflation'. But *what* inflation? At the moment, we have overall inflation at roughly 10% but inflation of food at roughly 20%. So is the overall inflation rate the same as the inflation rate for milk? It's not clear. Bad question.

Data thread from today's @IndependentSage briefing. 🧵
First, the @ONS Covid Infection Survey is being paused, and @CovidGenomicsUK is being retired. This will have implications for data reliability and availability going forward.

OK, I'm going to write a response to this maths problem, published in @DailyMailUK, that has caused a lot of comment, some thinking the answer is 1 and some thinking the answer is 9.

A thread. 🧵

dailymail.co.uk/news/article-1…
So, what answer is correct? Is it 1 or is it 9?

Many of us would go straight to the answer 1. That's because we know (or our children know, and have taught us), that there is a 'rule' for how you deal with the order of doing the calculation - do you do + first or ÷, for example?
Enter BIDMAS (or BODMAS).

"It stands for Brackets, Indices [or Order], Division, Multiplication, Addition and Subtraction."

That's the conventional order. Forget about indices [or order] for now - that's not important for this one.
