New studies have confirmed that Oxford-AstraZeneca vaccine not only prevents symptomatic infections but also reduces transmission of the virus. Researchers say the vaccine remained effective even after the first dose.
International Media have reported that the data from the studies indicate the vaccine may have an impact on transmission. Scientist says if a vaccine only stops from getting severely ill, but still catch and pass on the virus, then everyone will need to be immunized to be protected.
However, if the vaccine stops spreading the virus then it would have a far greater impact on the pandemic as each person who is vaccinated indirectly protects other people too.
It found that those who had been vaccinated with a single dose of the vaccine were less likely to test positive with a PCR test.
The study conducted on 17,000 people in the UK, South Africa and Brazil showed protection remained at 76 per cent during the three months after the first dose. This rose to 82% after people were given the second dose.
More than 9.6 million people have already received the first dose of their Covid-19 vaccine globally.
There are currently over 104 M Coronavirus cases across the world.
