LONDON: AstraZeneca and the University of Oxford today began new trials to test a modified vaccine against the Beta variant, which first emerged in South Africa.
They include people who have been fully vaccinated with two doses of the original Oxford-AstraZeneca vaccine or an mRNA vaccine such as Pfizer as well as those who have not got the jab at all. “Testing booster doses of existing vaccines and new variant vaccines is important to ensure we are best prepared to stay ahead of the pandemic coronavirus, should their use be needed,” said Andrew Pollard, chief investigator and director of the Oxford Vaccine Group at the University of Oxford.
This is all just PR/Marketing hype 'We want to sell more doses; OK, let's say that a third dose is very useful' Ooops.... 'that comment is leading to a lack of confidence in our vaccine' TODAY: 'There is no evidence a third jab is needed'
