This is the best answer I can give u to your question which was: What is one way that flue strains can vary from one another?
When vaccines are being developed for an upcoming flu season—which occurs about six to nine months in advance—researchers do their best to predict which of the various possible strains will be circulating. Making this job even tougher is the fact that flu viruses continually change over time, producing new strains that the body’s immune system doesn’t recognize. The type-B virus changes gradually, a process called antigenic drift. With type A, the changes can be gradual…or they can be abrupt and major, a process called antigenic shift.
