The UK became the first country to approve this new vaccine yesterday, and Moderna says it can supply millions of doses by the end of the year.
A spokesperson for the HSC said: “We await further information from the [Joint Committee on Vaccination and Immunisation] regarding the detailed deployment of vaccines for the autumn booster programme.”
Dr Nicola Brink, Director of Public Health, said in January that a fourth round of booster shots was likely to occur in the autumn, and the States later confirmed in July that a select group would be offered a dose before the end of 2022.
That includes people aged 50 and over, care home residents and workers, frontline health staff, the immunocompromised and their households, and unpaid carers.
But it remains unclear when the autumn booster will be available to eligible islanders.
