The skin-crawling horror of being British and needing to ask people to nominate you for prizes [I was genuinely amazed and horrified when I found out this was how most people won scientific prizes - by ASKING to be nominated]

No such thing a patient zero for Sars-cov-2 in the UK. There were *at least* 1300 importation events which kicked off transmission chains...

For years afterwards Boris cursed that they didn’t just read his CV, with its mesmerising Latin quotes, but unfortunately they asked him to demonstrate his skill set.

Vaccinating 4 million people in the UK (see below for details) could cut over 60% of deaths. It's not impossible for the UK to achieve this by the end of January. Hundreds of thousands of those people have had one dose already #EndGame 💉

I’ve been asked many times about how many people there are in each vaccination priority group, and how quickly we might see a reduction in COVID-19 mortality. The estimates in this table from the excellent @COVID19actuary are extremely useful. Full link:

Fortunate for everyone that lots of laboratory scientists were going in the office & lab to help us understand immunity to SARS-COV-2, virus evolution & vaccine design all the way through the pandemic. I can't do my job under a WFH mandate.

Thinking about similarities between long covid (SARS-CoV-2) and fatigue after glandular fever/IM (EBV) "Six, 12, and 24 months after infectious mononucleosis, 13%, 7%, and 4% of adolescents, respectively, met the criteria for chronic fatigue syndrome."

Angry Scientist - if you don't like someone's research/analysis, write a paper about it, don't send angry/weird emails to the female ECR authors 🙄

@ras_nielsen Sorry to hear this, as it was an interesting paper. Integrity will have its rewards for you in the long term, I am sure.

@alanmcn1 @devisridhar I actually think better weather will help a lot - 'illicit' socialising currently happening indoors will be more likely to move outdoors. People are really willing to embrace outdoor interactions as long as it's not sub zero and pissing it down.

@ChrisJ30900467 @mrhorsdusujet @NHSEngland @nhsuhcw It starts to protect from 12 days after the first vaccination, so Maggie will have increased protection from 20th December, and she will be fully protected (by her second jab) from first week of January :)

Boris, stop telling people they can only catch coronavirus from people they don't know!!! Most transmission is from your nearest and dearest, as everyone at Westminster has first hand experience of in EVERY wave!

2. You might have another nasty respiratory virus - even rhinovirus (common cold) can knock you around if it's a type you haven't had before/for a while. Note the Y axis: flu is really the dominant resp virus right now, even more so than RSV.
