Adimmune Corp (國光生技) on Thursday said it is developing a COVID-19 vaccine in cooperation with the National Health Research Institutes, and plans to run animal tests in the second quarter if its research proceeds smoothly.
The Taichung-based firm has been working to develop the vaccine utilizing its recombinant protein technology since acquiring a genetic sequence from the US Centers for Disease Control last month, Adimmune spokesman Pan Fei (潘飛) told the Taipei Times by telephone.
As the virus’ sequence reportedly evolves and appears different in separate regions, the company is attempting to determine whether the difference is considerable enough to affect the efficacy of a vaccine, Pan said.
“Though the novel coronavirus’ genetic sequence is 70 percent similar to that of the SARS virus, it is still not easy to make the vaccine,” he said.
Earlier this month National Taiwan University managed to isolate the virus strain of COVID-19, and Medigen Vaccine Biologics Corp (高端疫苗) on Monday said that it expects to conduct clinical tests for its vaccine in the second half of this year.
Adimmune would not use the isolated virus strain during its development to protect the safety of its research team, Pan said, adding that it is hard to forecast when it would enter the human trial stage
The Central Epidemic Command Center on Thursday said that an infected Taiwanese businessman returning from Zhejiang Province in China last month had antibodies against the virus in his blood.
However, Adimmune said that those antibodies would not help in the development of vaccines.
“Antibodies are created by patients’ immune systems. However, our goal is to produce an antigen against the virus, which is different,” Pan said.
Taiwan’s foreign exchange reserves fell below the US$600 billion mark at the end of last month, with the central bank reporting a total of US$596.89 billion — a decline of US$8.6 billion from February — ending a three-month streak of increases. The central bank attributed the drop to a combination of factors such as outflows by foreign institutional investors, currency fluctuations and its own market interventions. “The large-scale outflows disrupted the balance of supply and demand in the foreign exchange market, prompting the central bank to intervene repeatedly by selling US dollars to stabilize the local currency,” Department of Foreign
ENERGY ISSUES: The TSIA urged the government to increase natural gas and helium reserves to reduce the impact of the Middle East war on semiconductor supply stability Chip testing and packaging service provider ASE Technology Holding Co (日月光投控) yesterday said it planned to invest more than NT$100 billion (US$3.15 billion) in building a new advanced chip testing facility in Kaohsiung to keep up with customer demand driven by the artificial intelligence (AI) boom. That would be included in the company’s capital expenditure budget next year, ASE said. There is also room to raise this year’s capital spending budget from a record-high US$7 billion estimated three months ago, it added. ASE would have six factories under construction this year, another record-breaking number, ASE chief operating officer Tien Wu
The EU and US are nearing an agreement to coordinate on producing and securing critical minerals, part of a push to break reliance on Chinese supplies. The potential deal would create incentives, such as minimum prices, that could advantage non-Chinese suppliers, according to a draft of an “action plan” seen by Bloomberg. The EU and US would also cooperate on standards, investments and joint projects, as well as coordinate on any supply disruptions by countries like China. The two sides are additionally seeking other “like-minded partners” to join a multicountry accord to help create these new critical mineral supply chains, which feed into
For weeks now, the global tech industry has been waiting for a major artificial intelligence (AI) launch from DeepSeek (深度求索), seen as a benchmark for China’s progress in the fast-moving field. More than a year has passed since the start-up put Chinese AI on the map in early last year with a low-cost chatbot that performed at a similar level to US rivals. However, despite reports and rumors about its imminent release, DeepSeek’s next-generation “V4” model is nowhere in sight. Speculation is also swirling over the geopolitical implications of which computer chips were chosen to train and power the new
