AstraZeneca’s Covid vaccine is best for keeping people out of hospital and preventing deaths from the virus, a study finds.
Only 1.52 percent of people who received the Oxford-made vaccine were admitted to the wards after contracting the virus.
And only 0.03 percent, or one in 3,000, died of the disease.
In comparison, 1.99 percent of those who received Pfizer were hospitalized with the virus, and 0.15 percent died.
The AstraZeneca vaccine has formed the backbone of the UK vaccine rollout, with 25 million people already getting the shot.
But in May, an alternative to the jab was recommended for people under 40, amid concerns about a rare blood clot disappearing. More than 21 million people have received the Pfizer vaccine.

Researchers in Bahrain and at New York-based Columbia University conducted the study between December and July, which was published as a pre-print.
They tracked hospitalizations and deaths among people who contracted the virus in Bahrain, an island nation in the Middle East, among the unvaccinated and those who received their shots.
Delta Covid variant twice as likely to land patients in hospital, study shows
The Delta variant doubles the chance of hospitalization, research shows.
It was already known that the Covid strain first identified in India is up to 50 percent more transmissible than the previous dominant Alpha strain, which emerged in Kent.
But the largest study to date comparing the two shows that those infected with the Delta strain are 2.26 times more likely to be hospitalized.
Delta is also 1.45 times more likely to see people entering the emergency room who need emergency treatment.
Scientists claimed this is more evidence that the same traits that make the variant spread faster also increase levels of the virus in those it infects, making them more seriously ill.
The authors of the study, led by Public Health England and Cambridge University, said their results should be used by hospitals for planning, especially in areas where the Delta variant is on the rise.
dr. Anne Presanis, senior statistician at the university, said: ‘Our analysis shows that in the absence of vaccination, a Delta outbreak will place a greater burden on health care than an alpha epidemic.
“Getting fully vaccinated is primarily critical to reducing an individual’s risk of symptomatic infection with Delta and, most importantly, reducing a Delta patient’s risk of serious illness and hospitalization.”
The study also included the Chinese Sinopharm and Russian Sputnik jabs, both of which were worse at preventing hospitalizations than their European counterparts.
Of those who received the Sinopharm vaccine, 6.94 percent were hospitalized and 0.46 percent died — which was the worst performance of the four vaccines.
Of the Sputnik recipients, 2.24 percent were hospitalized, but only 0.09 percent died from the virus.
The results showed that those who did not receive the vaccine were most likely to be hospitalized or die if they got the virus.
Of the unvaccinated, 13.22 percent who contracted the virus were hospitalized and 1.32 percent died.
The Bahraini researchers said in their study, “All four vaccines reduced the risk of coronavirus infections, hospitalizations, ICU admissions and deaths compared to unvaccinated individuals.”
dr. Simon Clarke, a microbiologist at Reading University, said: The sun: ‘This study shows that people in the UK can be confident that they are getting the best vaccines available.
“AstraZeneca and Pfizer offer good protection.”
The Chinese Sinopharm vaccine has been the main injection in Bahrain, which is home to nearly 1.5 million people.
More than 569,000 people have been vaccinated with the shot.
In comparison, 245,000 residents received the Pfizer shot, 169,000 received the AstraZeneca vaccine, and 73,000 received Sputnik.
Results from clinical trials suggested that the Pfizer vaccine was most effective in preventing Covid hospitalizations and deaths.
But experts have warned that these numbers may not be comparable when jabs are handed out in the real world, when other factors could influence their impact.
Of the 3,000 AstraZeneca recipients included in the study who contracted Covid, only 45 were hospitalized (1.52 percent) and only one died of the virus (0.03 percent).
Of the 2,000 Pfizer recipients who contracted the virus, 40 were hospitalized (1.99 percent) and three died from the virus (0.15 percent).
Of the 3,000 Sputnik recipients who contracted the virus, 77 were hospitalized (2.24 percent) and three died (0.09 percent).
For the Sinopharm vaccine, there were 24,000 cases, of whom 1,683 were hospitalized (6.94 percent) and 112 died (0.46 percent).
And among the unvaccinated, nearly 65,000 caught the virus, of whom nearly 9,000 were hospitalized (13.22 percent) and 857 died (1.32 percent).
More than 1.5 million people have received the US-made Moderna vaccine in Britain, but this was not included in the study.
