Oxford, Engineering (WTVO) – Scientists at the University of Oxford have found that people vaccinated with COVID-19 are less likely to spread the virus if infected.
Scientists examined records of contact with 150,000 people followed from the first case of about 100,000 people. NBC News.. The sample reportedly included people who were fully or partially vaccinated and those who were not vaccinated. Scientists have investigated how the vaccine affected the spread of the virus in people with breakthrough infections.
Researchers investigating the Pfizer and AstraZeneca vaccines have found that both vaccinations reduce the transmission of the virus. If the exposed person was completely vaccinated with the Pfizer vaccine, people were 65% less likely to test positive, while the AstraZeneca vaccine reduced it by 36%. If someone received the vaccine only once, the risk of infection was reported to be much higher.
The study was just posted Thursday and has not yet been peer-reviewed, but the findings were said to be reliable by scientists unrelated to the study. One of these doctors was Dr. Aaron Richterman, an infectious disease specialist at the University of Pennsylvania.
“This is the highest quality study we have ever done on the issue of infectivity in vaccinated people infected with Delta,” said Richterman.
recently study People in Singapore may get rid of the virus from their bodies faster in vaccinated people than in unvaccinated people, and the level of delta variants in infected people is the same regardless of vaccination status. However, he was vaccinated, who found that his virus levels had dropped by day 7.
However, the study found that the defense against infection in vaccinated individuals could decline over time, and those who were completely vaccinated and had breakthrough cases were vaccinated. It has been shown that the likelihood of spreading the virus 3 months after vaccination is the same as for unvaccinated individuals.
Doctors such as Susan Butler-Wu, a clinical microbiologist at the University of Southern California, said masks and tests remain important while community infection rates remain high.
“Vaccines need to be combined with other measures to reduce the amount of virus exposed, such as by masking and testing,” Butler Wu said. “The name of the game here is an additional measure.”
