An expert committee convened by Singapore’s health ministry has recommended all residents medically eligible for Covid-19 vaccination to take shots as they become available, although it said vaccination should remain a voluntary option, Reuters reports.

The recommendation comes as Singapore’s success in controlling the virus makes some question whether they should take the jabs. The city-state has been reporting almost zero new local cases daily over the last few weeks.

The expert committee, convened in October, recommended achieving as high a level of population coverage for Covid-19 vaccination as possible to reduce the overall proportion of the population that is susceptible to the disease and the likelihood of uncontrolled chains of transmission, a statement released on Sunday said.

Singapore has approved the Pfizer-BioNTech Covid-19 vaccine, the first batch of which arrived on Dec 21. It has signed advanced purchase agreements and made early down payments on several vaccine candidates, including those being developed by Moderna and Sinovac. It expects to have enough vaccines for all 5.7 million people by the third quarter of 2021.

The government has said the vaccines will be free, voluntary and given first to healthcare workers and the elderly.
