ZURICH: Austria should offer some healthcare staff and other key workers a fourth COVID-19 jab, the National Vaccination Board said in updated guidance published late on Thursday (Dec 23), citing risks from the fast-spreading Omicron variant of the coronavirus.
But it said that there was not enough scientific data for it to recommend that fourth shots be given more widely.
"In view of an imminent Omicron wave, (a fourth vaccination) can be offered in high-risk areas (to exposed healthcare personnel, for example) and in systemically critical areas from six months after the third vaccination," the board said.
Austria said on Wednesday that it will tighten restrictions again from Dec 27 to slow the spread of the Omicron variant.
While that three-week lockdown slashed daily COVID-19 infections from record levels, the country is bracing for another surge. Several hundred Omicron cases have been confirmed already.
In its updated guidelines, the National Vaccination Board said that fourth COVID-19 shots could be given "off label" to groups in healthcare and other critical areas following medical consultation.
"There is still no evidence that this additional vaccination can prevent infections. However, it can be assumed that serious illnesses can be prevented," it said.
