What other developments do we expect during the COPCOV study?
During the COPCOV study, evidence may emerge about the efficacy of various drugs for the treatment of COVID-19. This information will be very important but is unlikely to answer the question of the COPCOV study: COPCOV is the only large-scale prevention study currently running and aims to determine if chloroquine and hydroxychloroquine can safely prevent COVID-19.
Vaccines to prevent COVID-19 have recently been licensed for use in certain countries. Sufficient production and distribution of COVID-19 vaccines will take time, with global equitable access, particularly in rural hard-to-reach populations of resource-limited countries, likely to take years. We need all the tools at our disposal to protect our health workers and maintain resilient health systems. Drugs to prevent COVID-19, like the ones tested in COPCOV, remain much needed.
