Health authorities on Tuesday started administering Covid booster jabs to people aged 30 and above at walk-in centres or after appointment through the vaccination portal.
People can receive the booster jab as long as six months have elapsed since the second dose of a Pfizer, Moderna, or AstraZeneca vaccine, or the single dose Janssen.
Those who received the Janssen vaccine can only get their booster shot at the walk-ins, the health ministry had said.
Walk-in centres operate in all districts between 8am to 6pm on weekdays and 8am to 1pm on Saturdays.
Non-gesy beneficiaries can also visit the walk-ins every Friday.
