The majority, or 97%, of Singapore's workforce have been vaccinated, and about 75,000 employees are unvaccinated as of 5 December, reports The Straits Times, citing the Ministry of Manpower. This marks a one-third decrease since 17 October, when there were 113,000 unvaccinated workers. This reduction comes ahead of a 1 January 2022 requirement for all staff to be fully vaccinated to be able to return to the workplace. Employees can also return if they have recovered from Covid-19 in the past 270 days or have a negative pre-event testing (PET) result for the duration they are required to be at the workplace. The PET result is valid for 24 hours.
