LONDON — The primary real-world information from the U.Okay.’s inoculation program has given an perception into how efficient vaccines have been towards Covid-19.
The vaccine developed by Pfizer and BioNTech vaccine was the primary shot to be accredited and rolled out within the U.Okay. in December. The over-80s, well being care staff and care house employees had been the primary in line to be immunized. That was quickly adopted by the shot developed by British frim AstraZeneca and the College of Oxford.
Listed here are 4 charts summarizing how efficient these vaccines are, and the way they’re enjoying their half within the battle towards the pandemic:
Falling deaths within the over-85s
Because the aged had been the primary to be vaccinated, it is noticeable that Covid deaths are falling quickest in these age teams. The chart beneath seems to be at Covid deaths for Scotland, with a decline seen within the over-85s group simply because the vaccination program began to assemble tempo.

A surge in antibodies
A blood test study published last week by Imperial College London showed that almost 14% of the British population now has antibodies against the coronavirus. While this doesn’t necessarily mean immunity, what was interesting was the results from the people that had been vaccinated and how high their antibody levels were. 18,000 participants of the 155,000 person study had been vaccinated and the results are in the chart below.

A separate study in England has shown the highest percentage of people testing positive for antibodies was those aged 80 years and over, at 41%, which the statisticians said was “most likely due to the high vaccination rate in this group.”
The real-world effectiveness of the Pfizer shot
Public Health England looked in detail at how effective the Pfizer-BioNTech vaccine has been so far in protecting against symptomatic disease. The chart below shows that one dose is 57% effective at protecting against symptomatic Covid-19 disease in those aged over 80 (from 28 days after the first dose).
Vaccine effectiveness is calculated using a mathematical statistic called an odds ratio, click here for the full data and methodology.
Public Health Scotland also collected data on the AstraZeneca-Oxford vaccine for all age groups. The chart shows that, by the fourth week after receiving a first dose, the Pfizer-BioNTech and Oxford-AstraZeneca vaccines were shown to reduce the risk of hospitalization from Covid-19 in up to 85% and 94%, respectively.

Since the start of the vaccination rollout, the U.K. has immunized all its top four priority groups, on target. It now aims to vaccinate all over-50s by mid-April, and all adults by end of July, two months ahead of a previous target.
As of Sunday, over 20 million people have received their first dose of a vaccine, and almost 800,000 have received both doses, government data says.
The U.K.’s vaccination program has been widely hailed as a triumph amidst tragedy; the U.K. has seen the fifth-highest number of infections worldwide, after the U.S., India, Brazil and Russia, with over 4.1 million infections recorded and 123,083 deaths, the fifth-highest death toll in the world, according to Johns Hopkins University.
