The Europe wave is not coming here *because we've already have it*.
Instead, it's taken two months for our "Kent" strain (B117) to spread across the EU and start a new wave there. OLD restrictions work on the OLD strain but NOT Kent. So cases go up as soon it is dominant. 2/6
If cases start steadily going up here it will be for one of two reasons (or both!):
1) As we found out in Dec, OLD mitigations don't work on B117. But opening up with OLD mitigations relying on vaccination to help keep cases down & chaotic mass testing (esp schools). 3/6
2) A new variant starts spreading here (e.g. S Africa or a new one) which can infect vaxxed people -> and so spreads quickly as it can infect way more people than B117 and so out-competes it.
This is real threat of the EU wave - but we CAN IMPOSE QUARANTINE on arrivals. 4/6
It is unbelievable to me that the govt has known for 8+ months that Covid is airborne and done almost nothing to support better ventilation in schools, workplaces, retail, hospitality. Or fixed test & trace & *supported* isolation properly so that we can open up MORE safely. 5/6
So basically, it is entirely on the Govt if we have another wave this summer - not the EU.
This line from Boris today makes me think that he knows his roadmap won't be enough & is preparing his scapegoat.
God forbid they take responsibility for anything ever. 6/6
PS It's on European governments that they ALSO failed to learn the basic pandemic lessons and sat around while B117 spread over the past few months.

Cases in school age children are definitely going up while other age groups are flat or falling (slowly).
Some of this increase is undoubtedly because of mass lateral flow device testing rolled out to schools. But NOT all. 1/7
*Primary* school age kids are *not* getting routinely tested - tests are still symptom based. We see little change in cases week of 8th March but we start seeing quite rapid increase 14th March onwards.
This is consistent with increased spread since schools opened. 2/7
*Secondary* school age cases started going up around 8 March - when mass testing started.
But if it was *only* mass testing, then you'd expect cases to flatten the next week (15th March onwards), as similar number of LFDs done both weeks.
Firstly, the current increases in Europe are because B117 (the Kent strain) has become dominant there - move than 70% in Denmark, NL, 50-70% in France, Belgium, Itlay, Germany & Austria. 2/11
As with us in Dec, they didn't act decisively to stop its spread - instead they've been in semi-restrictions (similar to our tier 3) - enough to bring *down* cases of old variant but not enough to stop B117.
It's now 4 weeks since Scotland & Wales started a phased return to primary schools (secondary schools went back last week) & 2 weeks since all schools in England went back.
What is happening? 1/15
First let's look at Wales. They started sending young kids back to nursery and primary schools 22nd Feb. Older primary school kids & secondary school went back last week.
Wales publish new Covid incidents in schools - and (unsurprisingly) incidents are increasing. 2/15
Secondly, Scotland. There we have case data by age.
Primary school kids only get a test if they get symptoms. School staff can get tested without symptoms if they want. All positive cases from lateral flow device tests (LFDs) are PCR confirmed.
Tonight a reduction is vaccine supply is being widely reported leading to a pause in rolling out vaccination to the under 50's... bbc.co.uk/news/uk-politi… 1/5
Basically, we gave about 11 million people their first dose mid Jan - mid Feb. They need their 2nd dose by end April.
We've been vaxxing about 2.5m/wk last few weeks, but let's say vax supply drops to about 2m/wk for April. Then we need ALL those doses to honour 2nd doses. 2/5
Once most of those are done, we can start rolling out vaccination to new people again (adults under 50) in May.
Assuming we can ramp up to 3.5m/wk from May, we can still offer everyone a 1st dose by mid July. 3/5
