U.K.-based drugmaker GlaxoSmithKline announced Thursday that it has started shipping its Fluarix flu vaccine to U.S. pharmacies and healthcare providers. Last year’s ineffective vaccinations are top of mind as drugmakers and physicians hope this year’s vaccine formula is on target.

More than half of the influenza cases reported during the 2014-2015 flu season came from a mutated virus strain that the vaccine didn’t protect against.  Last year, flu vaccines from various manufacturers had an effectiveness rate of just 23%, while in other recent years, the vaccine has had an efficacy rate of 47% to 60%, according to the Centers for Disease Control and Prevention.
