How will Pfizer vaccine storage requirements affect the program?
It was initially thought that the Pfizer vaccine should be stored at -70 ° C to be effective, meaning that it could only be delivered to general practitioners with the facilities to maintain it at that temperature.
However, according to the latest results, the Pfizer vaccine no longer needs to be stored at extremely cold temperatures. If approved by regulators, that means the vaccine can be stored in standard medical freezers for two weeks, which will have a significant impact on distribution.
It is understood that the vaccine batches are broken down into doses of 75, in order to give the vaccine to elderly residents and staff in homes with more than 50 beds to avoid wastage.
The Oxford vaccine does not need to be stored in such cold conditions – it can be stored at temperatures between 2 ° C and 8 ° C.
This means that it is more mobile than the Pfizer jab and therefore more easily deployed in care homes of different sizes and in private homes for individual doses.
Will people get vaccines 24 hours a day?
Vaccine Minister Nadhim Zahawi said vaccinations from 8 a.m. to 8 p.m. will continue for people over the age of 80, but more and more people in other age groups are starting to receive the vaccine. vaccine, “it becomes much more convenient for them in the first hours”.
Mr Zahawi expects the program to be operational in London hospitals and 50 vaccination centers by February.
In addition, three Birmingham hospitals have started offering round-the-clock vaccinations for health and social workers from the night of January 20.
Offering vaccinations overnight will speed up the rollout and allow the government to meet its goal of vaccinating 32 million people – 60% of Britain’s adult population by the spring, announced on January 11.
What about the new variant of the coronavirus? Will the vaccine still protect us?
The South African variant and the Brazilian variant have threatened to undermine the vaccine and testing gains of recent months.
The Medicines and Health Products Regulatory Agency (MHRA) expects vaccine adjustments to be needed as it has already started examining how quickly a modified jab could be approved, and Matt Hancock said that he was “very worried”.
As of February 16, 217 cases of the South African variant of Covid-19 had been identified in England. Since some cases are unrelated to travel, door-to-door testing will take place in parts of England.
It comes as scientists have discovered that the Kent coronavirus variant is mutating to mimic the South African variant, which could make current vaccines less effective.
It was announced on February 7 that studies of the University of Oxford-AstraZeneca jab have shown that it does not protect against mild and moderate infections of the South African variant.
However, vaccines against the new coronavirus variants should be ready by October, the team behind the University of Oxford / AstraZeneca jab said.
On January 25, Moderna Inc announced that its vaccine was effective against the Kent and South African variants. Vaccine deliveries will take place in the spring.
Britain is also set to approve a fourth vaccine against the coronavirus, after a vaccine tested in the UK was found to be highly effective against the Kent variant, which the Health Secretary called “breakthrough”.
Sixty million doses of the Novavax vaccine have been secured by the UK, which Mr Zahawi himself injected into as part of the trial, which was found to be 89.3% effective in preventing the coronavirus among participants.
Professor Paul Heath, the lead investigator of the Novavax Phase 3 trial, said he believed vaccines could be adapted “at the rate” to target new coronavirus variants after the Novavax vaccine turned out to be effective against Kent variant.
Importantly, it has been shown to be very effective in preventing infection with the Kent variant which Boris Johnson said on Jan.22 could be up to 30% more deadly than the original.
However, the most promising, January 16, The Telegraph revealed that Britain would have the capacity to vaccinate the entire country against new strains of coronavirus within four months, once a new ‘super-factory’ opens this year.
The government is currently looking to the future, and Boris Johnson has said the elderly and vulnerable in the UK could have a coronavirus vaccine every year, like the rollout of the annual flu shot.
