SANTIAGO, Aug 4 (Reuters) - Chinese pharmaceutical Sinovac Biotech Ltd on Wednesday said it will build a fill-and-finish vaccine plant in Chile with an investment of $60 million, consolidating its presence in the Latin American nation that has used its COVID-19 shot the most.

Chile has run one of the world's fastest vaccination campaigns, so far fully vaccinating more than 60% of its population, including with 19.6 million doses of Sinovac's CoronaVac already delivered.

The plant will be built in the Santiago region in the first quarter of 2022. Sinovac will also build a research and development center in the northern region of Antofagasta. (Reporting by Fabian Cambero Editing by Jonathan Oatis)
