One in 25 Britons who have been hospitalized with Covid since December have been vaccinated, No10 scientific advisers have found.
A study by SAGE shows that 1,800 out of 43,000 patients admitted with the virus since December 8 had received at least one dose of Pfizer or AstraZeneca injection.
Most contracted the coronavirus shortly before appointment or a fortnight later, before immunization had begun.
Researchers who conducted the study confirmed that the results should in no way be seen as proof that the vaccines are not working as well as hoped.
Instead, they believe that people have taken unnecessary risks after receiving the vaccine, or caught the virus while traveling to and from vaccine centers.
At a meeting on March 12, SAGE called for better communication with the government on how long it will take for the injection to work – usually around a fortnight or more.
Approximately 300 patients were admitted to hospital 14 days after their first dose, with SAGE clarifying that ‘100 per cent vaccine is not effective’.
They were mostly over 80s, the most vulnerable to Covid and struggling more to fight the disease.
The group of experts said going forward they will investigate whether any of the issues are linked to other Covid changes that are feared vaccines will not be as effective.
A government study has shown that the Pfizer and AstraZeneca vaccines are more than 90 percent effective in reducing deaths and hospitalizations after both doses.
One in 25 Britons who have been in hospital with Covid since December have been vaccinated, the Government’s Scientific Advisory Group for Emergencies appeared today. The number of Covid hospital admissions among vaccinated persons is shown in blue, as opposed to non-vaccinated in red.
A study by SAGE shows that 1,800 out of 43,000 patients admitted with the virus since December 8 had received at least one dose of Pfizer or AstraZeneca injection. The graphs highlight how just a fraction of total entries are among people with jabbed
Most patients in the hospital in the last few months caught the virus shortly before their appointment or in the few days after, before immunity had kicked in.
SAGE was able to work this out by working backwards from the date they entered. The stimulation period of the virus is at least five days
Effectiveness is about 85 and 80 percent twelve weeks after the first injection, and they prevent about 60 percent of people from spreading the disease.
The new paper, published today as part of the latest installment of studies used by SAGE to advise ministers, looked at 42,788 Covid hospital patients up to 5 March.
Of those who became ill after the vaccination, the average time between receiving their injection and admission to hospital was five days.
Since it usually takes five days after the infection with Covid to become ill, it is likely that most had become infected shortly before or around the time they received the injection.
SAGE said it believes many people would have taken unnecessary risks after receiving the vaccine, assuming they were protected.
But they accepted that many vulnerable people could be seen inadvertently traveling to and from the profession.
Some vaccinated patients were also treated for non-coronavirus purposes and were asymptomatic but were subsequently identified as PCR positive.
Writing in the study, the experts said: ‘Elderly and vulnerable people who have been inactive, could be seen and unknowingly infected both during the process end-to-end vaccination, or shortly after vaccination through behavioral changes where they mistakenly assume immunity. ‘
The small number of people infected with the virus more than two weeks after being vaccinated was over 80.
People in this age group are the most vulnerable to Covid and are among the least likely to be able to resist an immune response.
Minutes from its 83rd meeting on March 11 show SAGE: ‘It may be expected that a large number of people who develop symptoms within a few days of the first dose may suggest some behavioral change after vaccination (and before immunity has developed).
It is therefore important that communication around vaccines reinforces the need to maintain safe behavior.
Some infections may also occur during the end-to-end vaccination process (ie including trips to and from vaccination).
‘Many of those included in the study would have been vaccinated at a time when community frequency was very high.
‘While the Covid vaccines used in the UK are very effective, a vaccine is not 100 per cent effective, and some people will be hospitalized even after completing their full immunization schedule (high confidence ).
It will be especially important to monitor the frequency of different forms present in this group by ordering to understand any possible immune escapes. ‘
Does Britain have enough supply for a second dose of people? France threatens supply of Pfizer jabs from EU and delay of AstraZeneca from India could stop distribution for even LONGER
Britain’s supply of second-dose vaccines is entering troubled waters as the delivery of both Pfizer and AstraZeneca injections is at risk of being stopped by foreign governments.
India has banned the export of AstraZeneca injections to be made at the Serum Institute so that they can use them for its own citizens, delaying the shipment of five million doses going for the UK.
And EU officials are on the verge of halting shipping of Pfizer vaccines – which the UK must complete second doses for around 10 million people by mid-June.
Insiders say AstraZeneca’s supply can be made entirely in the UK and that the five-million dose increase from India was not critical to meeting government targets, meaning that delivery from India could be disrupted. be a disappointment rather than a crisis.
But nationwide Pfizer doses are made in factories in Europe – the company and its partner BioNTech have huge facilities in Belgium and Germany – and international shipping is vital to ensure people get a second their dose.
More than 12 million doses of Pfizer have already been sent to Britain and the NHS will need at least the same number again by June to ensure everyone gets their booster injection within three months, such as promised by the government.
Physicians have already stopped giving vaccination to patients for the first time so they can prioritize all Pfizer stores – which are now at risk of becoming extinct. ‘erosion to stop – for the second dose of existing patients.
No10 today insisted that Britain is still on track to meet its vaccine targets despite supply problems.
A leading government source said: ‘We are confident in vaccine targets, offering first doses to people over 50 by 15 April and all adults by 31 July, as well as second doses.’ It is estimated that around 12 million doses will be delivered in April.
But now jobs are expected to be delayed open as political tensions rise and other countries suffer more and more disease.
India is in the grip of a second wave and is holding vaccines from the Serum Institute so that it can vaccinate one billion citizens, and things are recurring in parts of western Europe, where distribution has been less successful than in Britain. As a result, politicians are trying to stick to vaccine supplies to use them on their own citizens without protection.
And the Moderna vaccine, which is set to be the third and newest to be introduced in the UK from next week, also needs to be imported from Europe, although it has in Switzerland which is not part of the EU.
