BANGKOK (REUTERS) - Thailand's Health Ministry said on Thursday (Sept 2) that its Covid-19 vaccine regimen of China's Sinovac followed by British-developed AstraZeneca was safe and successfully boosted immunity among its first 1.5 million recipients.

Thailand in July became the first country in the world to mix a Chinese vaccine and a Western-developed vaccine as cases and deaths in the country surged and the government struggled with vaccine supplies.
