Creating a Good Bird Flu Vaccine

Creating a good bird flu vaccine is proving to be a lot harder than researchers thought it was going to be due to how much this bird flu changes. It is always changing and developing in more ways and this makes it hard to make one bird flu vaccine that will work all of the time. The scientist working on the bird flu vaccine are monitoring the bird flu very well to watch for any significant changes that will affect the usability of the bird flu vaccine. All of the data that they collect can be used to make the bird flu vaccine more and more effective.
