LONDON, March 23 (Reuters) – Booster COVID-19 jabs could be needed in the autumn to prevent another wave of infection, cannabis oil uses Britain’s chief scientific adviser said, although he added that there were no indications that the level of protection offered by the shots was waning.

“There will be a need to think about booster jobs for vaccines in the autumn I suspect, particularly thinking about getting high level of immunity to cover things over the winter,” Patrick Vallance told a Downing Street briefing on Tuesday.
