Old vaccines protected against three strains, which included two varieties of type A viruses and only one variety of the type B virus. Now, some of the vaccines will include one more variety of the type B virus. Since the quadrivalent strain is new, vaccines that require needle injections will be limited. However, all nasal sprays will have all four varieties. Nasal sprays will be made with a live but weakened version of the virus and thus, only healthy people between the ages of two and 49 would qualify for this type of vaccine. Pregnant women cannot get the nasal spray.
