London:A team of UK researchers has analysed the likely impact that a Covid booster shot will have on Omicron and says it could provide around 85 per cent protection against severe illness.
According to the BBC, the protection is a bit less than vaccines given against earlier versions of Covid. But it means the top-up dose should still keep many people out of the hospital.
The modelling, from the team at Imperial College London, is based on limited information on Omicron.
The researchers said there is a high degree of uncertainty until more real-world information is gathered about this new variant that is spreading quickly.
