WHO Director says not to over-interpret numbers coming out of vaccines’ trialsighly effective, must be used, life-saving

A World Health Organization (WHO) advisory group statement on the AstraZeneca COVID-19 shot is expected very soon, a WHO spokesman said on Wednesday (March 17).

Global health experts have come under increasing pressure to clear up questions over the safety of AstraZeneca’s vaccine, as the number of countries suspending its use grows in a blow to Europe’s vaccination rollout.

The European Medicines Agency has said it is investigating reports of 30 cases of unusual blood disorders out of 5 million recipients of the AstraZeneca vaccine. In total, 45 million COVID shots have been delivered across the region.

Kate O’Brien, director of WHO’s Department of Immunization, Vaccines and Biologicals, said that a WHO vaccine safety panel that met on Tuesday (March 16) was assessing whether medical events such as blood clots were actually related to vaccination.

“We should not over-interpret these specific numbers that come out of trials. They are highly effective vaccines, they are all life-saving vaccines, they are all safe vaccines and we should get on with deploying them,” she told a news conference.

“So, anybody who is offered vaccine should take whatever is being offered by the programme and ensure that the vaccines that are being produced are used to their maximum benefit,” she said.

The WHO-backed COVAX vaccine sharing facility has an agreement to send out “hundreds of millions” of Johnson & Johnson shots, O’Brien said.

The chair of the of the Strategic Advisory Group of Experts (SAGE) on immunization, Alejandro Cravioto, said the committee recommends the use of the Johnson & Johnson vaccine for countries reporting high spread of the virus variants.
