LONDON The Oxford-AstraZeneca coronavirus vaccine appears to substantially reduce transmission of the virus, rather than simply preventing symptomatic infections, UK researchers have suggested.
The rate of positive PCR tests declined by about half after two doses, according to preliminary results by researchers at the University of Oxford that have yet to be peer reviewed.
Their analysis, released as a preprint on Tuesday,
also supports spacing out doses and estimates good efficacy after just one shot of the Oxford-AstraZeneca vaccine.

also supports spacing out doses and estimates good efficacy after just one shot of the Oxford-AstraZeneca vaccine. The study did not measure transmission directly for example, by tracing contacts who were infected by study volunteers. But the researchers did collect regular nasal swabs from some participants and found that the rate of positive PCR tests fell by half after two doses of the vaccine. After one dose only, the rate of positive tests fell by 67%.

Researchers from the University of Oxford have determined that the AstraZeneca COVID-19 vaccines do not only protect people from the deadly and contagious disease but also drastically reduces viral transmission.

AstraZeneca Shots Reduce Viral Transmission
According to the New York Times, the study is the first to document such effect on the novel coronavirus, and it appears like the AstraZeneca shots are the first one to have that effect.
To measure the impact on the transmission of the virus, the team of researchers swabbed participants each week to look for signs of the virus if they find no virus even if the person has been infected with COVID-19, it means it cannot spread to others.
