The Brazilian clinical trial for a high-profile Chinese Covid-19 vaccine has been suspended after health authorities reported a "severe adverse" incident.
Brazilian health regulator Anvisa said it took place on 29 October, but did not give further details.
The Sinovac vaccine is one of several in final-stage testing globally.
But China has already been using it to immunise thousands of people at home in an emergency use programme.
