Dr. Rachata is in his second year of residency, focusing on travel medicine at Mahidol University's Faculty of Tropical Medicine in Thailand. He's deeply interested in travel and tropical medicine, as well as other public health issues. Currently, he's working on his thesis, which explores why some international travelers are hesitant about getting the dengue vaccine. Dr. Rachata is eager to learn more about vaccine hesitancy and hopes to apply his findings to help improve vaccination rates, especially among travelers.
