I quote from your first link: "The flu vaccines used in China, which are recommended by the World Health Organization, can prevent three strains - H1N1, H3N2 and B/Victoria - the dominant strains in the previous years. However, they have limited effect against B/Yamagata.
"The dominant strains for each year may be different, and it is expected B/Yamagata will not be the dominant strain for flu outbreaks in the next one or two years," Mr. Feng said.
The Chinese CDC is encouraging the development of vaccines that can prevent all four strains, and it is expected that at least one company on the mainland will be able to produce such vaccines by the fall, he said."
To me that sounds as if they do have their own program. It would not surprise me if they are also not looking for the Holly Grail - one shot for all strains. I am sure they are following the work at Georgia State University and other research facilities around the world. They are pretty good at taking the best ideas and developing them.
Are the cells from flies? I just ask because very common, quick lifespan. Easy to sterilize?
I believe the Protein Sciences cells are from moths. But I am not sure; I think my son researched it and told me that. I found this link that gives a little more information (but not the kind of insect): BEVS Platform Technology. Here is one more link that I did not see the type of insect; but it goes into more detail: https://link.springer.com/chapter/10...-540-68182-3_6.

Thank you fisheye. If not flies, and you think moths, why moths? It certainly sounds like a cleaner insect, and I want to learn
Our son said that he was familiar with baculovirus expression. I just bugged him for more information and he looked again and gave me this link: https://en.wikipedia.org/wiki/Fall_armyworm. Then he lost me in the explanation!
You have yourself quite an intelligent son, Sir fisheye. Yes, a very common moth, I wonder if that has anything to do with it as well?
Thank you for the link.
