Pregnant women and cancer patients on active treatment are among the sub-groups of individuals that can also be vaccinated, said the multi-ministry task force (MTF) in an update on Monday (May 31).
It noted that more people have been vaccinated both globally and locally, which has provided more evidence on the efficacy and safety of vaccine use.
This is especially in relation to specific sub-groups where clinical trial data had not been as substantive.
The task force said: "The Expert Committee on Covid-19 Vaccination has been monitoring the evidence and developments around the world closely, and has revised the guidance for... specific sub-groups of individuals."
Pregnant women will be able to register and book a vaccination appointment from June 4 onwards if they are part of the population group eligible for vaccination.
But MTF added that they should discuss the risks and benefits with their doctors to make an informed decision on the vaccination.
"There is currently no evidence to suggest that the Pfizer-BioNTech or Moderna Covid-19 vaccines may cause harm to pregnant women or their babies," MTF said.
"However, the Committee recognises that the amount of data collected on this population segment is still much smaller compared to data on the general population."
