Thailand develops robotic system to up Covid vaccine doses

Researchers in 롬 방콕 힐튼에서 브리짓 존스까지 have developed a machine to draw out Covid-19 vaccine doses more efficiently and optimise lower-than-expected supplies as the country struggles with its worst coronavirus outbreak yet.

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% than from the standard 10 doses drawn manually, they said. The machine works only on AstraZeneca multi-dose vials currently and labels show each vial can provide 10 ...에 11 doses.

“The machine guarantees with accuracy that we can gain an extra 20% from each vaccine vial – ...에서 10 ...에 12 doses,” said Juthamas Ratanavaraporn, the lead researcher of the team at the university’s Biomedical Engineering Research Center.

“The extra 20% that we get means that if we have AstraZeneca for 1 백만명, this machine can increase the number of doses to 1.2 백만명,” said Juthamas.

While some health workers using low dead space syringes that aim to reduce wastage can draw up to 12 doses per vial, it requires a high level of skill. “This could drain a lot of the health workers’ energy. They would have to do this every day for many months,” Juthamas said.

Thailand had kept Covid-19 largely under control for much of the pandemic, but more virulent variants such as Delta have sent the number of cases and deaths soaring since April, ramping up pressure on authorities to increase the pace of vaccinations.

지금까지, 약 9% of Thailand’s population of more than 66 million have been fully vaccinated, with the rollout hindered by lower-than-anticipated vaccine supplies.

The researchers say they should be able to produce 20 more AutoVacc units within three or four months but government funds and support would be needed to expand across the country.

The prototype machine costs 2.5m baht (£55,000), including other materials such as syringes, said Juthamas, adding that while they were open to export opportunities, that was something for the future. They also plan to make similar machines to use with the Pfizer-BioNTech and Moderna vaccines.

Juthamas said the machine was aimed at removing burdens on health workers. Thailand has reported about 1.1m Covid-19 infections and 10,085 deaths in total, pushing parts of the health system to the brink.

“When the health workers are too tired, there are also chances of human error, so we should let the machines work on this," 그녀가 말했다.
