The results indicate that the vaccine may help stop the spread of the virus
With the continuation of vaccination campaigns globally with the emerging anti-corona virus (Covid-19) vaccine, great news appeared that carries hope for imminent transformations and the start of controlling the pandemic.
In the first study conducted to discover the effectiveness of two vaccines for the Corona virus, researchers in Scotland reported on Monday that the first doses of the vaccines “Pfizer-BioNTech” and “AstraZeneca-Oxford” “Oxford-AstraZeneca” significantly reduced hospital admissions due to infection with the “Covid virus” -19 “Among the elderly.
In a report published by the American “Washington Post” newspaper, writers William Booth and Carla Adam say that public health officials in Britain are looking optimistically at the results of recent studies that show that vaccines have begun to reduce the spread of the Corona pandemic.
Arne Akbar, president of the British Society of Immunology, described the initial results as “very promising”.
Scottish researchers analyzed data for the entire country’s population of 5.4 million, with 1.1 million people (about 20% of the population) receiving a first dose of the Pfizer or Oxford vaccine.
By comparing the data of those who received the vaccine with others, the researchers found strong evidence of the effectiveness of the vaccine.
For his part, Aziz Sheikh, a professor at the University of Edinburgh and one of the principal researchers supervising the study, said that examining the results of vaccination for adults 80 years or older showed a decrease of 81% in hospital admissions by the fourth week.
Sheikh warned that the immunity provided by the first doses of vaccines could diminish, but he explained that researchers are currently working to monitor the data of people who received the second dose.
Reducing the burden of hospitals
“The other good news is that vaccines will actually help reduce the burden on NHS hospitals due to the Covid-19 virus,” study co-author Josie Murray of the Scottish Public Health Agency said in a statement to reporters.
The writers of the Washington Post report went back to explaining that the previous results about the effectiveness of vaccines came exclusively from clinical trials, including what showed that the “Pfizer-Biontech” vaccine was approximately 96% effective, in contrast to the new Scottish study that monitored the results of vaccination on the ground.
The Scottish research was published in a draft version on Monday and has not yet been peer-reviewed. Sarah Gilbert, a co-developer of the Oxford vaccine, said in a statement that the vaccine’s high efficacy in protecting people over the age of 80 years after receiving a single dose enhances “confidence in using this vaccine on adults of all ages”.
A second study
In a second study, also published yesterday, scientists of the Public Health Authority in England provided preliminary data showing that the “Pfizer-Biontech” vaccine is very effective in protecting against symptoms of the “Covid-19” virus and from infection with corona.
The researchers examined a group of health care workers who received the vaccine, to see if they were suffering from symptoms of “Covid-19” and found that one dose reduced the risk of infection by more than 70%, and rose to 85% after receiving the second dose.
These results indicate – according to the researchers – that “the vaccine may also help to stop the spread of the virus, as you cannot transmit the virus unless you are infected with it.”
