J&J, via its subsidiary Janssen, had already received $456 million in March. The new money will allow the company to ramp up production so that doses are ready for shipping if and when the drug receives regulatory approval. (Photo by Mark RALSTON / AFP)

Johnson & Johnson se convirtió el miércoles en el cuarto grupo farmacéutico en comenzar la fase 3 de ensayos clínicos de su vacuna experimental contra la covid-19 en Estados Unidos.

Si los resultados son positivos, la compañía espera poder presentar una solicitud de autorización de emergencia ante la Agencia de Medicamentos de Estados Unidos (FDA) "a principios de 2021", según un comunicado.

En el ensayo de Johnson & Johnson participarán 60.000 voluntarios de tres continentes a los que se les suministrará una sola dosis.
