Professor David Salisbury, who was in charge of vaccination at the Ministry of Health until 2003, said that a single dose already provides “91% protection”.

Professor Salisbury said: “We did this before when the amount of flu vaccine for children was limited. It was clear that a single dose to a child could actually double the vaccination. “

“And again, the numbers are really easy.

“Looking at the New England Journal of Medicine treatise on the Pfizer vaccine, a single dose provides 91% protection and two doses provide 95% prophylaxis.

“So you’re only getting 4 percent on the second dose.

“In the current situation, it is highly recommended to use as many initial doses as possible for the risk group and return with a second dose only after doing everything.”

JAB HOPES

It comes as The new Oxford Jab will be approved as early as Monday.

British Vaccine Minister told the sun on Sunday The large effort was heroic And we exhibited “the best British at every stage”.

Former Prime Minister Tony Blair urged the government to rethink its vaccination program, saying it “must be changed and radically accelerated.”

He said the Pfizer vaccine is a two-dose jab, but the first dose still provides “substantial immunity.”

writing Independent He states: “You should consider using all the doses available in January as the first dose. That is, do not maintain half of the second dose.

“Then, as more production is rolled out, there is enough for the second dose. The single dose vaccines, 30 million Johnson and Johnson vaccines, will be with us by the end of January. must.

“You should aim to use them all in February.”

He added that front-line medical staff and the most vulnerable people should continue to be prioritized, but this should not “postpone vaccination of others.”

Authorities are also reportedly considering a “single shot” program for young people.

Need more data

However, Blair’s comment was rejected today by Professor Wendy Berkeley, a member of Nervtag.

Professor Berkeley told the Commons Science and Technology Commission: “I think the problem with that (Blair’s suggestion) is that the vaccine is based on two doses and the efficacy is based on it.

“To change at that point, we probably need to see more analysis done from the clinical trial data.”

She agreed with Graham Stringer’s proposal, a member of the Labor Relations Commission, that such changes to established vaccine policies are “too risky.”

About half of all hospitals and two-thirds of GPs across the UK have not yet received Pfizer vaccine delivery.

About new strains

“It’s a much more difficult call. I use the Pfizer vaccine more aggressively, so I vaccinated as many people as possible with a single vaccination.

“I think it’s important to think carefully in the current situation.”

He said the new strain of the virus was “concerned” and that there should be more reason for the government to spread the vaccine program to people with a single dose.

In just a few days, the person who received the first dose of the vaccine will come forward to administer the next shot.

A Pfizer spokeswoman said: “As previously reported and published in the New England Journal of Medicine, the final primary efficacy analysis of ongoing Phase 3 clinical trials shows that participants have a vaccine efficacy rate of 95% starting after 7 days. Was shown. The second dose.

Some protection from the vaccine appears to begin after the first dose (52%), but according to information for healthcare professionals approved by the UK Regulatory Authority (MHRA), individuals start with the second dose. Of the same vaccine that may not be protected until at least 7 days later. To provide maximum protection, the vaccine should be given twice at 21-day intervals, which correlates with the level of neutralizing antibodies.

“Healthcare professionals are encouraged to continue to follow the official guidance on vaccination.”

Comments come after Prime Minister Boris Johnson excludes giving priority to southern England for Covid Jab.

Over 500,000 British have received jabs.
