Nearly two years after the COVID-19 outbreak, China has granted approval to its first antibody combination therapy for COVID-19 treatment, adding a tool to the world’s fight against the disease.
A team from Tsinghua University, along with the Shenzhen People’s Hospital, has accomplished the task in 20 months. It would usually take 10 years. “It can reduce the rate of hospitalization and death by 80 percent,” said Zhang Linqi, leader of the research team.
The new antibody drug is immediately effective after being used. Moreover, the therapy can protect people, especially those whose physical condition doesn’t allow vaccination (接种疫苗), from becoming infected (感染) by COVID-19 for around 9 to 12 months, said Zhang.
How does it work? When a virus infects a cell, it relies on an important type of protein: the spike proteins (棘突蛋白) on its surface. The spike proteins serve as a key to unlocking a cell. If a virus cannot enter a cell, it will disappear immediately. The job of our antibodies is to block the virus from entering cells. So its target is very precise. In addition, thanks to the coordination between the two antibodies, it is highly efficient in preventing the virus, according to Zhang. The qualities of the new drug make it especially useful for high-risk groups, such as frontline medical workers and people not suitable for vaccination due to various underlying health problems.
The new drug is expected to come to the market soon, but it’s not cheap. That’s because of limited production. Noting that China has used science and technology to fight COVID-19 since the beginning of the outbreak, Zhang said, “Science is the key to solving the issue. Science has shown its power in all sectors, from medical treatment, medicine and vaccine development to prevention and control measures.”
