The spring booster programme has been extended until the end of this month because of the sharp rise in Covid cases.
Eligible islanders who haven't had their booster are being contacted directly with an invite to book an appointment at the vaccine centre.
Anyone who hasn't been contacted by Monday 18 July is being asked to call the helpline on 0800 735 5566.
People who are in the following categories can get another dose:
- Islanders aged 75 and over
- Immunosuppressed islanders aged 12 and over
Two new Omicron variants have led to the sudden increase in infections.
Updated statistics will be published by the government later today (14 July).
Last week's statistics said that 1808 people were known to have coronavirus in Jersey.
Around 83% of over 75s have had their Spring Booster.
