Belgian PM Alexander De Croo told Euronews that they would only give booster jabs to those who are vulnerable to COVID-19 as healthcare workers in some countries are not yet vaccinated.
Belgium re-imposed some pandemic measures as coronavirus cases and hospitalisations increase in the country.
The government extended mandatory mask-wearing in indoor settings and encouraged people to be more "prudent", stating that they would not limit activities. They also extended use of the health pass -- the COVID safe ticket -- to more events.
"Wearing a mask is not always something very comfortable but it is a method very useful and effective at preventing virus transmission," Prime Minister Alexander De Croo said at a press conference.
"It's clear that if we did not have vaccines, we would today be in a catastrophic situation in our hospitals," De Croo said at a press conference later in the day.
Vaccine booster doses only for vulnerable individuals
For the moment, booster doses of COVID-19 vaccines are available to vulnerable individuals, PM De Croo told Euronews earlier, stating that for the moment third doses of the jabs were not being given to the general public.
"For the general public, we have decided not to do it, because we think that it is ethically not the right choice because the benefit of a booster shot to the general population in Belgium would be way lower than the benefit of giving a first shot to people in our neighbourhood outside of Europe," De Croo told Euronews.
"So in Belgium we have made that choice and for the moment [to] stay away from a booster shot because we don’t believe it is justified."
