The risk of coronavirus infection is greatly reduced after the first dose of AstraZeneca or Pfizer vaccine. A study in the United Kingdom has revealed this information. News from the BBC.
The study says the vaccine works the same way for people over the age of 65 as for all other adults. Research by The Office for National Statistics (ONS) and the University of Oxford has found strong antibodies in the body of people of all ages after the AstraZeneca and Oxford vaccines.Researchers say that after taking two tickers, an effective response has been created in everyone.
The study was conducted on the basis of corona testing of 360,000 people in the UK. However, the study has not yet been reviewed. It was not even published.The first study found that taking the first dose of Oxford-Astrageneca or Pfizer-Bioentech vaccines reduced the risk of corona infection in humans by 75 percent.For those who were vaccinated between December and April last year, corona infections, including symptoms, decreased by 84 percent three weeks after vaccination. And asymptomatic corona infection has decreased by 56 percent.
Those who took the second dose of the Pfizer vaccine had a 90 percent reduced risk of infection. However, it was not possible to provide this information in the case of the AstraZeneca vaccine. Because of the late start of the immunization program, very few people have been able to get a second dose of the AstraZeneca vaccine.Studies have shown that two vaccines are effective against the Kent type of coronavirus (B118). A new type of coronary heart disease is now spreading in the UK.
University of Oxford Nafield Department of Population Health senior researcher. Cohen Powell said the decision to widen the gap between the two doses of the vaccine could be reconsidered based on the evidence.He said the information available on protection against new corona infections after taking a single dose of the vaccine supports the decision to increase the interval between the first and second doses. This interval can be up to 12 weeks.
However, researcher Powell added that people can be re-infected with the coronavirus even after being vaccinated. Others from them can also be infected. For this reason, he emphasizes social distance and the need to wear a mask.
The second study was run on about 47,000 adults who had taken a dose of the vaccine. Strong antibodies have been found in the body of people of all ages after vaccination. Vaccines can stimulate the human body's defenses against the virus, he said. The researchers say that these antibodies can be effective in the human body for up to 10 weeks.
The study also found that the Oxford and AstraZeneca vaccines were more effective in those under the age of 60 than in those under the age of 60. Two doses of Pfizer can produce high levels of antibodies in all ages. Another surprising finding from the study was that the second dose of Pfizer vaccine may be more effective in preventing immunizations in young people over the age of 60 than in young people.
