Yong trained in pediatrics at the Chulalongkorn University Faculty of Medicine and completed board certification by the Medical Council of Thailand in 1978. He was subsequently accepted as a faculty member, and received a research fellowship grant at the hepatology department at King's College Hospital Medical School during 1983–84.[3]
He has since worked continuously at Chulalongkorn, mostly focusing on teaching and research, and obtained professorship in 1990. He has served as the head of the faculty's Viral Hepatitis Research Unit and Molecular Biology Research Unit since 1992 and 1996, respectively.
Research
Yong has held a deep interest in research since medical school. He first published in national journals during his first year of residency, and began publishing internationally in 1989, with his work on hepatitis B vaccination.[4] He is the author or co-author of over 400 publications in the fields of gastroenterology, hepatology, and virology indexed by the PubMed database,[5] with about 20,000 citations and an h-index of 65 as calculated by Google Scholar.[6]
His works originally focused on the fields of pediatric hepatology and viral hepatitis, especially in applications to the Thai healthcare system, on which such works have had significant impact. Later on they expanded to include virology studies in general. Yong is widely recognized for his work on genetic sequencing and detection of the H5N1avian influenza virus in Thailand, which saw outbreaks beginning in 2004, and is regarded as the national expert on the subject.
COVID-19
During the COVID-19 pandemic in Thailand, Poovorawan served as an advisor to Prayut Chan-o-cha's government. He often exaggerated the efficacy of the disputed CoronaVac, which the country heavily relied on for immunization, including suggestion that a third dose of CoronaVac may result in an immunity more or less comparable to that of Pfizer-BioNTech's vaccine,[7][8] or arguing for the mixing Sinovac's and AstraZeneca's vaccines based on a very small human trial.[9]
In July 2021, his article in Thai Wikipedia was vandalized, which includes text accusing him of being "Sinovac's salesman". A complaint was filed by Poovorawan's attorney, which led to an arrest of the wrongdoer within 3 days.[10]
