Research: One dose of BioNTech and AstraZeneca vaccine reduces infection rate by 65 percent


According to research conducted in the UK, it was announced that a single dose of the Oxford / AstraZeneca and Pfizer / BioNTech vaccine provided 65 percent protection against Covid-19.

In the study conducted by the University of Oxford and the Office of National Statistics, the Covid test results of more than 350,000 people who were vaccinated in the UK between December and April were analyzed.

In the study, which attracted attention as the first study examining all age groups vaccinated, it was reported that the vaccine protected all age groups by two thirds.

72 PERCENT PROTECTS AGAINST ASYMPTOMATIC INFECTION

In the tests performed on people who were vaccinated after 21 days, the rate of protection from infections was reported to be 65 percent, and it was stated that the vaccines were 72 percent effective against asymptomatic infection and 57 percent against symptomatic infection.

As the second doses of the AstraZeneca / Oxford vaccine were administered to very few people, the study, which included two doses, will be announced later, while the team scientists said the findings support the UK’s decision to delay the second doses and prioritize the first vaccinations to the elderly and more vulnerable people.

95 PERCENT STRONG ANTIBODY RESPONSE DETECTED

Dr. “There is no evidence that vaccines are less effective among the elderly or those with long-term health problems,” Koen Pouwels said.

According to real world data, the protective effect of the vaccines against the highly contagious and more lethal British variant is shown, while Dr. David Eyre said 95 percent of people who received a single dose of vaccine had a strong antibody response.

Public Health of Scotland announced in February that a month after receiving a dose of BioNTech and AstraZeneca vaccine, the risk of hospitalization due to Covid-19 dropped to 85 percent and 94 percent, respectively.
