Permanent Secretary for Health, Doctor James Fong has confirmed there is no shortage of booster doses yet.
Some people have told us they were turned away from the vaccination site before 3pm and were told by health care workers they have reached their quota for booster doses for the day.
Dr. Fong says vaccination sites have to close at 3pm so that the staff can make sure all their other administrative work is sorted.
He adds they are also short on staff as some need to be rested and others are in isolation.
The Health Ministry earlier confirmed that more booster doses are scheduled to arrive in the country by the end of this month.
Vaccinations sites are open from 9am to 3pm.
