Covid: Delaying second dose of vaccine increases risk of new resistant strain, Sage papers reveal

Delaying doses of coronavirus inoculations will increase the chances of a vaccine-resistant strain of Covid-19 emerging, government scientists have warned. In new reports, released by the Scientific Advisory Group for Emergencies (Sage), experts also warned that resistant new variants were a “realistic possibility” driven by the virus reacting to increasing levels of natural immunity among the population. The government’s decision to delay the second dose of vaccines to 12 weeks rather than three, to try and give more people some protection from the virus, has sparked anger among frontline health workers who fear they are being left at increased risk from infections. There have also been suggestions from Israel, that have yet to be fully validated, that the protection from a first dose could be far less than originally thought.
