Covid-19 vaccines are working 'spectacularly well' say experts

New data suggests the Covid-19 vaccines reduce a person’s risk of being hospitalized four weeks after their first dose by up to 94 percent.

Research from Scotland shows that one month after the first dose of the Oxford sting, a person’s risk of being hospitalized is reduced by around 94 percent.

The AstraZeneca vaccine “works and works in the elderly,” according to government scientific adviser Sir Patrick Vallance.

And those who had the Pfizer shock had a risk reduction of up to 85 percent between 28 and 34 days after their first dose.

The elderly are at high risk of serious illness. The data for the two combined shocks showed that the risk of hospitalization for people in this group decreased by 81 percent one month after their first dose.

The older people in the study were more likely to have the AstraZeneca push.

Experts studied coronavirus hospitals admission in Scotland among people who had their first sting.

Their data has been compared with those who have not yet had a vaccine against the virus.

Scientists from the Universities of Edinburgh, Strathclyde, Aberdeen, Glasgow and St. Andrews and Public Health Scotland (PHS) analyzed data on people who had either received Pfizer / BioNTech vaccination or who had been developed by University of Oxford scientists with AstraZeneca.

According to the experts, the vaccines are said to “work incredibly well”. They expect similar results across the UK.

They stressed that the study did not intend to examine the differences between the two shocks as they were offered to different populations.

Lead Researcher Professor Aziz Sheikh, Director of the Usher Institute at Edinburgh University, said: “These results are very encouraging and have given us good reasons to be optimistic about the future.

“We now have evidence nationwide – nationwide – that vaccination offers protection against hospitalization after Covid-19.

“Overall, we are very, very impressed with these two vaccines.

“If we go beyond the testing stage, you never know what the results will be, but this is in the field and they both work incredibly well.

“Right now we don’t have the numbers to do these age-stratified tests for different vaccine types, but we’ll have them soon.”

“But both [vaccines] work spectacularly well, which means we haven’t made a direct comparison between the two at the moment. “

Sir Patrick said the Scottish study was “very encouraging” but cautioned that the estimates have “confidence intervals” – meaning the actual number may be more or less effective than the reported one.

“But AZ works,” he added. “And it works for the elderly.”

Defense Department Science Advisor Professor Dame Angela McLean added, “Ninety-four is a very encouraging number, but 94 is not 100. We have to live with that, and that’s why it’s so important to get really, really high coverage. ”

The surveyed data was collected between December 8th and February 15th, when 1.14 million vaccines were administered to 21 percent of the population in Scotland.

The Pfizer vaccine was given to 650,000 people while 490,000 received the Oxford / AstraZeneca push.

The researchers examined general practitioners’ records of vaccinations, hospital admissions, death registrations, and laboratory test results, and compared the results of those who received their first sting with those who did not.

Dr. Teresa Lambe, Associate Professor at Oxford University, said: “When we first started this journey, we could only hope that a year later, real data would show how strong our vaccine was against hospitalization for serious illnesses.

“It’s a great day for all of us, especially for the team that has worked so hard and is monumental in the fight against the coronavirus.”

Professor Andrew Pollard, Chief Investigator for the Oxford Vaccine Study, said, “We are delighted that the real-world evidence reported today by the University of Edinburgh confirms that both the Oxford-AstraZeneca and Pfizer vaccines have a very significant impact against hospitalization with Covid-19 disease.

“Vaccines work. We now need to make sure everyone, everywhere, is protected. “

Dr. Jim McMenamin, National Covid-19 Incident Director at PHS, said: “Across the entire Scottish population, the results show a significant effect in reducing the risk of hospitalization with a single dose of vaccine.

“For anyone who offers the vaccine, I encourage them to get vaccinated.”

Dr. McMenamin added that the data are “encouraging” when looking at the effects of the vaccine against the UK variant of Covid-19.

He added that in Scotland cases of the South African variant have been linked “almost exclusively” to travel.

“It is unlikely that we will then be able to see anything about the effect of the vaccine for other variants, but certainly for the UK variant that we saw during the period of the study that we are demonstrating a very encouraging vaccination effect for the entire program,” said he.

Professor Chris Whitty, Chief Medical Officer for England and co-director of the National Institute for Health Research (NIHR) said: “This research provides encouraging early data on the effects of vaccination on reducing hospital stays.”

Chris Robertson, Professor of Epidemiology in Public Health at the University of Strathclyde, added, “These early national results give reason to be more optimistic about controlling the epidemic.”

The data has been published on a pre-printed form, ie it has not yet been peer-reviewed or published in a journal.
