Research collaboration is needed to inform quarantine policies for health-care workers

To date, only the US Centers for Disease Control and Prevention has released a formal guideline specifically for vaccinated HCWs, which largely depended on the presence of symptoms.4 Similar policies have been informally adopted in Malaysia and in the Indian state of Odisha, but most countries maintain the same policy regardless of vaccination status. HITAP's international work is supported by the International Decision Support Initiative (iDSI). iDSI is funded by the Bill & Melinda Gates Foundation, the UK's Department for International Development, and the Rockefeller Foundation. HITAP has also been supported by the Health Systems Research Institute to study the challenges of developing a monitoring and evaluation framework for COVID-19 vaccination policy in Thailand, and by the National Research Council of Thailand for an initiative around COVID-19 vaccination policy research in Asia.
