2. Phase I clinical trial of China’s COVID-19 vaccine achieves positive results
According to a report published by the Chinese research team led by Academician Chen Wei in the leading British medical journal The Lancet on May 22, the results of the first phase clinical trial of the COVID-19 vaccine showed that the vaccine was safe and can induce the body to quickly produce an immune response.
Chen Wei said in a press release issued by The Lancet that these results represent an important milestone. However, she also noted that the relevant results must be treated with caution as the ability to elicit an immune response does not necessarily mean that the vaccine can protect people from infection. "The development of the COVID-19 vaccine is very promising, but we still have a long way to go before this vaccine can be used by everyone," Chen added.

5. Japan develops tear test breast cancer technology
Kobe University in Japan has successfully developed new technology for the detection of breast cancer using tears. The TearExo uses a special dropper with a built-in metal sheet to collect tears and conduct tests with precision instruments. It has been reported that the technology can detect whether tears contain cancer cells in 10 to 20 minutes, as well as whether the drug used by the patient being treated is effective.
