Global distribution of the AstraZeneca coronavirus vaccine remains undisturbed by the shot’s suspension in much of Europe following reports of blood clots in some shortly after immunization, the World Health Organization said.

The U.N. agency, which continues to recommend the vaccine, is helping provide doses to many poorer nations and said that the majority of those injections are being produced outside of Europe where the suspensions are now taking place.

The move by the WHO to reassure some countries comes as Australia said Tuesday that it would continue to use the vaccine, which Chief Medical Officer Paul Kelly said in a statement “is successful in protecting against covid-19.” Thailand’s prime minister also became the country’s first person to be vaccinated with the AstraZeneca shot Tuesday after briefly halting its own rollout due to blood clot concerns in Europe.
