https://www.cnbc.com/2020/05/18/ ... -vaccine-trial.html
实验组
Each participant received a 25 microgram, 100 mcg or 250 mcg dose, with 15 people in each dose group.
有效性
At day 43, or two weeks following the second dose, levels of binding antibodies in the 25 mcg group were at the levels generally seen in blood samples from people who recovered from the disease, the company said. Antibodies in the 100 mcg had antibodies that “significantly exceeded levels” in recovered patients.
The vaccine also produced neutralizing antibodies against Covid-19 in at least eight participants, the company said. Experts have said neutralizing antibodies appear to be important in acquiring protection.
副作用
The company said the vaccine was generally safe and well tolerated. To date, the most notable adverse events were seen in the 250-dose group where three participants developed “grade 3 systemic symptoms,” following the second dose, the company said.
展望
If the vaccine is found to be effective and safe to use, it could be ready for the market in early 2021, the company said.
