Thailand develops robotic system 'Auto Vacc' to draw out COVID-19 vaccine doses efficiently

Researchers in Thailand have developed a machine to draw out COVID-19 vaccine doses more efficiently and optimise lower-than-expected supplies.

Bangkok: As Thailand struggles with its worst coronavirus outbreak yet, researchers in the country have developed a machine to draw out COVID-19 vaccine doses more efficiently and optimise lower-than-expected supplies. Using a robotic arm, the "AutoVacc" system can draw 12 doses of the AstraZeneca vaccine in four minutes from a vial, according to researchers at Chulalongkorn University, who made the machine that has been used at the university`s vaccination centre since Monday. That is up 20% from the standard 10 doses drawn manually, they said. The machine only works on AstraZeneca multi-dose vials currently and labels show each vial can provide 10 to 11 doses. "The machine guarantees with accuracy that we can gain an extra 20% from each vaccine vial - from 10 to 12 doses," said Juthamas Ratanavaraporn, the lead researcher of the team at the university`s Biomedical Engineering Research Center.
