February 03, 2021 The Oxford-AstraZeneca coronavirus vaccine appears to substantially reduce transmission of the virus, rather than simply preventing symptomatic infections. Courtesy photo 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. ....

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. 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%. ....
Oxford s Covid vaccine could save tens of thousands of lives because it can cut the likelihood of catching coronavirus and passing it on by around two thirds, scientists say. Modelling produced by SAGE members from Warwick University predicted that more than 150,000 more people could die in 2021 if lockdown rules were lifted in March or April and vaccines did not stop people from spreading the virus. But with a 60 per cent infection-blocking capability – slightly lower than the 67 per cent that Oxford claims its vaccine is capable of – this could be halved, saving tens of thousands of lives. Oxford researchers, who are making their jab with pharmaceutical firm AstraZeneca and delivering more than a million of doses per week to the UK, confirmed last night that trials suggested the jab would stop most people from passing on the virus. ....
The Oxford/AstraZeneca vaccine could be the holy grail in the fight against coronavirus, according to a leading pharmacologist. The preliminary results of a study conducted by researchers at the University of Oxford found the efficacy from two standard doses of the vaccine administered three months apart to be 82.4%. But it is the fact it also seems to dramatically cut transmission - by around 67 per cent - after just one dose that will mean lockdown measures can be lifted sooner, a former chair at the Faculty of Pharmaceutical Medicine said. Dr Gillies O’Bryan-Tear said the results, which have yet to be peer reviewed, were the first definitive estimate of the impact of vaccination on transmission rates. ....
The mother of a teenager who abused Chris Whitty in the street has revealed how she was horrified at her son s rudeness, has taken away his PlayStation and is making him apologise to the Government s Chief Medical Officer. She told MailOnline it was her 15-year-old son who filmed himself repeatedly accusing Prof Whitty of lying to the nation about the pandemic that has claimed 100,000-plus lives. The 47-year-old housewife and mother-of-two revealed she had told her eldest son to make another video apologising to him. She also said she had reprimanded him by taking away his games console but she was not grounding him because he is already suffering enough because of the lockdown . ....
