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.Speaking to the UK's Science Media Centre (SMC), Helen Fletcher, professor of immunology at the London School of Hygiene and Tropical Medicine, said the data in the study "suggest a possibility that the vaccine could have an impact on transmission but further follow-up would be needed to confirm this."Dr. Doug Brown, chief executive of the British Society for Immunology, told the SMC the study "hints that the Oxford/AstraZeneca vaccine may be effective in stopping people being able to transmit the virus."
