In total, the United Kingdom government has agreed to buy 355 million doses of the vaccine from seven different manufacturers as it prepares to vaccinate as many as 67 million people in the country as possible. The plan is to reduce age groups and at-risk groups so that everyone 18 years and over is vaccinated.
Non-medical personnel including volunteer paramedics are already being trained to administer vaccinations, which will be offered at about 1,000 community vaccination centers and 40 to 50 large-scale facilities in stadiums and conference venues, according to a government planning document.
Prime Minister Boris Johnson said Conservative lawmaker Nadhim Zahawi will oversee the country's biggest vaccine program in decades.
"Whichever way you cut the data - even if you only believe the full-dose data ... we still have efficacy that meets the thresholds for approval with a vaccine that's over 60pc effective", he said. It should be stored at an extreme cold temperature of minus 70 degrees Celsius (minus 94 Fahrenheit). The Moderna vaccine, which also needs to be stored at freezer temperatures, was also about 95% effective in clinical trials, the company said.
The British government hopes a combination of vaccines and mass testing will end the need for restrictions on business and everyday life it imposed to curb the spread of the coronavirus.
The prime minister said this week that officials hope to vaccinate "the majority of people who need more protection because of the Easter holiday".
"It appears that less than 3,000 people were given the schedule with the half-dose followed by the full dose of the vaccine".
The four-week national lockout in the United Kingdom is due to end on Wednesday, and will be replaced by a three-tier system of regional measures restricting business activity, travel and socialization. But some scientists have questioned the gaps in its report results. Later, they acknowledged a manufacturing issue had resulted in a half dose mistakenly being administered as the first dose to some participants. Neither the researchers at AstraZececa nor those at the University of Oxford were able to answer these questions. "So it's hard to weigh in on this", O'Brien, the chief of the department of immunization, vaccines and biologicals, said.
"If my GP rings me and says 'I've got an approved vaccine, ' I really don't care which one it is", he told the BBC.
