The first Vaccination Surveillance Programme report has been released today showing decent efficacy even on one dose of Pfizer where odds improved over a 4 week period and then seemed to plateau until second dose.
Efficacy = 57% (95% CIs 48-63%) from 28 days after the first dose of vaccination (table 1). Protection after the second dose rises to 88% after 7 days (95% CIs 84-90%)
HEALTHCARE WORKERS: protection against infection from a single dose of the Pfizer vaccine was 72% (95% CI 56-82%).(This corresponds closely with the data from Israel that suggested 75% protection against all infections (85% against symptomatic infection) after single dose.
CAUTION ⚠️ Follow up time still limited:
BUT early data suggest that that any cases that do occur in older vaccinated people are around as half as likely to lead to hospitalisation and/or death, so even if symptomatic : less severe.
@jburnmurdoch summarises both the Scottish and PHE report well in this article.
🦠🦠8,489 new cases but nearly a half a million Lateral Flow tests were carried out yesterday. Higher false negative rate. They seem to be replacing PCR testing increasingly.
⚰️⚰️⚰️ 548 (28 day cut off) deaths
⚰️💔⚰️💔 141,769 deaths total BY DATE OF DEATH
Death total as follows from today’s Gov COVID dashboard.
138,468 ONS/ stats authority deaths (Covid on death certificate) to 12/2/21
+
3321 deaths by date of death (28 day cut off)
= 141,789⚰️
We have now exceeded SAGE’s RWC scenario from July 2020 (85k deaths 1/7/20-31/3/21)
On 1/7/20 There were 56,061 COVID deaths (ONS/stats authority by date of death).
141,789 Covid deaths total to yesterday.
85,782 deaths since 1/7/20 despite 2 lockdowns, endless tiers and 11 weeks of vaccinations.
I see the same thought is occurring in America too.
So rapid tests have a pretty high false negative rate in the community. Repeat high quality Nasopharyngeal swabs from gagging kids is going to be challenging to say the least.
Covid US death toll: Imagining what 500,000 lost lives look like - BBC News
I’d be more impressed with the BBC if they 1/ troubled to get our own death figures right (we topped 140k Covid deaths yesterday, by date of death) and did the same visualisation. bbc.co.uk/news/world-us-…
So. @BBCNews to help you. If we laid the U.K. dead head to toe (allowing 6ft for each person - also the gap that was supposed to keep us safe) it would cover the distance (159 miles)nearly from London to Sheffield (169 Miles).
These are the data (complete with screenshots from the Government website) - Covid deaths by date of death to 20/2/21
@BBCNews We are about 1k deaths off SAGE’s July 2020 RWC (85k deaths between 1st July 2020-31st March 2021) despite 2 lockdowns constant tiers and vaccinations
