He has pioneered the use of the triple combination of interferon beta-1b, lopinavir/ ritonavir and ribavirin in the treatment of hospitalized COVID-19 patients, resulting in significantly faster clinical alleviation and viral load suppression. He and his team also pioneered the application of topical imiquimod before intradermal influenza vaccination, which results in protection against heterologous non-vaccine and antigenically drifted viruses.
