In a statement today, the ministry said the application automatically sends out appointment links based on the type of vaccine individuals choose.

“However, the application is currently facing technical difficulties and is sending booster appointment links to individuals who are 17 and below and also to those who have already received their booster shots, asking them to come in for a second booster,” it said.

The health ministry said its current policy only recommends individuals aged 18 and above to receive one booster dose for the time being.

“Parents and guardians of children aged 17 and below, as well as individuals who have already received their booster shots, should ignore the new appointment link. As for those who have already accepted the appointments, please cancel them,” it said.

The health ministry said that vaccination centres (PPVs) have already been informed about this technical glitch and have been instructed to refuse entry to those that fall in the categories stated above.

“The MySejahtera technical team is working to rectify this issue and we apologise for any inconvenience caused,” it said.

Last week, the health ministry released a statement allowing for booster vaccination appointments to be made through the MySejahtera application from March 21.

Members of the public can choose their preferred integrated vaccination centre along with a date and time.

The ministry also said those who had yet to receive a complete vaccination or booster dose, or parents who wished to bring their children for either the first or second dose could do so by booking an appointment at selected centres.

Alternatively, they could go to private doctors who offer paediatric vaccinations and booster doses, or at an offsite vaccination centre.
