It seems there are more flu shot options now than there have ever been before. That makes sense because of the scientific advances we continue to make every year. We know more about the flu virus than we ever have before.
The variety of flu shot options is also a product of the flu vaccine market and the society that market serves. The market is currently shifting towards the new, scientifically-supported flu shot options. They haven’t necessarily let go of older, more traditional options yet because they still work. And they’re still valuable!
