Chen Wei mentioned that as of September 2020, more than 100,000 viral sequences have been uploaded to public databases, including 60,000 high-quality whole-genome sequences were sampled from more than 105 countries and regions on 6 continents. The highly anticipated D614 mutation had no significant effect on the vaccine.

Recently, the Ad5-nCoV vaccine, which has been granted a national invention patent, will expand the scale of clinical trials for people aged 55 and over. Chen Wei explained that this group of people is more likely to become severely ill, so special attention should be paid to the effect of the vaccine in this group.
Chen Wei said that before this, the vaccine was the first in the world to announce phase II clinical results, verifying the immune effect of people over 55 years old for the first time, and the oldest volunteer was 84 years old.
