Answer:
It gives new ideas to achieve
Explanation:
Science fiction fascinates me. Science does not. Technology does. Combining all of them is one of the most interesting things to learn about. When an author of science fiction writes about an idea, like the idea of retina scanners, or holographic computers, it interests people, making them think, maybe we could bring this to reality. And then they do. Humans can do just about anything, and when they're interested in a topic, they're twice as likely to take it into legitimate consideration.
Hence, why we now have so many things that were nonsense years ago. Because science fiction is new, and science fiction is the future. If you told someone seventy years ago that one day we'd have self driving cars, they'd think you were nuts. Now they exist. Because some author came up with it, some CEO or millionaire though it was a good idea and told their employees to make it happen, and some engineer and/or scientist was smart enough to make it happen.
Hope this answers your question :)

Answer:
Viruses are prone to clumping together. Many times extensive sequence changes may not make a difference in antibody recognition. While sometimes small changes in HA are sufficient for a large antigenic distance. That is, with few mutations, some Hemagglutinins may be much less recognized by the antibodies.
Explanation:
As the virus replicates in the body of infected people, the immune system captures several pieces of viral protein, the antigenic antibodies, and produces antibodies against them. There are other types of immune responses, too, but they do not cause long-term immunity, so that is beside the point. The two main viral targets of the antibodies are Hemagglutinin and Neuraminidase, since they are the most exposed proteins of the virus. When antibodies associate with them, in addition to signaling macrophages and other types of defense cells that that foreign body (the virus) has to be attacked, they can still prevent the virus from working. An antibody that attacks the Hemagglutinin receptor recognition region prevents it from associating with cells. They are the so-called neutralizing antibodies.
