A fourth coronavirus jab may be needed to improve levels of protection, a vaccine boss has said. Chief Executive of Moderna, Stephane Bancel, explained that another vaccine this autumn would increase immunity as the efficiency of booster doses is likely to decline over the next few months.
Moderna is currently working on a vaccine tailored towards the Omicron variant that continues to spread rapidly across Scotland, the UK, and the world.
However, a fourth Covid vaccine is not yet needed, according to the Joint Committee on Vaccination and Immunisation (JCVI).The JCVI has advised the Scottish and UK Governments throughout the Covid vaccination process.
