‘Cause for concern’
Chief Scientific Adviser Sir Patrick Vallance said: “The new variant contains 23 different changes, many of them associated with changes in the protein that the virus makes. This is an unusually large number of variants. It’s also got variants in areas of the virus that are known to be associated with how the virus binds to cells and enters cells. So there are some changes, which cause concern in terms of how the virus looks.”
He added: “This virus transmits and spreads fast.”
The variant may have originated in the UK, Sir Patrick said: “There’s a large outbreak in the UK, it may have started here, we don’t know for sure.”
Earlier, SAGE member, and Director of the Wellcome Trust, Sir Jeremy Farrar tweeted: “The new strain of COVID-19 is worrying & real cause for concern & extra caution. Research is ongoing to understand more, but acting urgently now is critical. There is no part of the UK & globally that should not be concerned. As in many countries, the situation is fragile.”
Dr. Samantha Batt-Rawden, president of Doctors’ Association UK and a senior intensive care registrar in the South East of England commented: “We realise how disappointing the new restrictions will be for many today, especially those in Tier 4 areas. However, doctors across the UK, but especially those in the South East are telling us that the surge in cases is already putting hospitals and critical care units under enormous strain.”
Vaccines
Mr. Johnson said 350,000 people across the UK have now had the first dose of the Pfizer/BioNTech vaccine.
On Dec. 18, the US FDA granted emergency use of Moderna’s messenger RNA COVID-19 vaccine, the country’s second after the Pfizer/BioNTech product.
The Moderna vaccine, and the Oxford/AstraZeneca jab, are still being assessed by the UK’s MHRA.
Daily data
In Dec. 19’s daily data another 27,052 UK positive tests were reported and 534 deaths.
The total number of deaths within 28 days of a positive test now stands at 67,075.
There are 18,771 COVID-19 patients in hospital and 1,364 ventilator beds are in use.
