Thailand to shorten interval between AstraZeneca vaccine doses

Published June 23, 2021, 8:32 AM BANGKOK, Thailand A Thai medical committee has agreed to shorten the interval between two doses of the AstraZeneca COVID-19 vaccine to eight weeks from previously 10-12 weeks, an official said on Tuesday. The National Communicable Disease Committee has decided to shorten the interval due to possible spread of the Delta variant, Kiattiphum Wongrachit, permanent secretary of the Ministry of Public Health, said at a press conference. The number of people in Thailand infected with the Delta variant is increasing, and the variant is likely to replace the Alpha variant as the dominant strain causing infections, local media cited Yong Poovorawan, a senior virologist at Bangkok’s Chulalongkorn University, as saying.

Wary of Covid-19 vaccine shortages, Asian governments determined to develop home-grown shots

Reuters Asia-Pacific economies are racing to develop home-grown Covid-19 vaccines as supply shortages threaten to upend containment efforts and prolong the pandemic. Japan, South Korea, India, Taiwan, Thailand, Indonesia and Vietnam are all betting on multiple locally developed vaccine candidates after struggling to secure adequate supplies of shots from overseas. Although locally developed vaccines are unlikely to arrive in time to save sluggish vaccine roll-outs, authorities and scientific experts regard the approach as a longer-term investment. Many experts expect Covid-19 to circulate indefinitely. It means the emergence of variants resistant to existing vaccines and the potential need for booster shots to maintain immunity could fuel vaccine demand for years to come.

Dogs are better, faster, and cheaper for detecting COVID-19 than antigen and PCR tests, researchers say

June 2, 2021 Dogs are being trained to detect COVID-19 in Thailand, France, Britain, Chile, Australia, Belgium, Germany, and other countries, and preliminary studies suggest that their detection rate may surpass that of the rapid antigen testing often used in airports and other public places, The New York Times reports. Cells infected with COVID-19 have a specific scent that dogs can sniff out in seconds, even if the person doesn t have symptoms.  For dogs, the smell is obvious, just like grilled meat for us, Dr. Kaywalee Chatdarong, deputy dean of veterinary research and innovation at Bangkok s Chulalongkorn University, tells the Times. The six Labradors being trained at Chulalongkorn University accurately detect the COVID-19 virus 96.2 percent of the time in controlled settings, university researcher say, and studies have found results almost that impressive in Germany and the United Arab Emirates.
