Ear Infection Vaccine?!

It looks like someone has finally making progress in the medical industry. A potential vaccine has been created for childhood ear infections. "Vaccine could end children's ear infections GlaxoSmithKline has developed a vaccine that may help prevent ear infections, an ailment that has plagued children and their parents forever." As a parent having to deal with ear infections with my young kids, this would be a welcome advancement in the medical industry. I can't believe that a vaccine was actually created instead of yet another means to treat the symptoms which is well known to be much more profitable than actually creating a vaccine. I guess in this scenario, the vaccine had much more benefit from a social, medical and business viewpoint.
