Default Inhaled flu vaccine will NOT be recommended for use in 2016-17 flu season


I guess you could say they don't have the bugs worked out yet.

ACIP recommends against inhaled flu vaccine for next season

Federal vaccine advisors recommended against using the nasal spray vaccine, made by AstraZeneca's MedImmune and sold as FluMist, because of problems with vaccine effectiveness over the past three flu seasons.

The vote marks a dramatic turnaround for a version of the vaccine for which health officials have had high hopes. In 2014, the Advisory Committee on Immunization Practices (ACIP), a group of outside experts that helps guide Centers for Disease Control and Prevention (CDC) vaccine policy, made a preferential recommendation for nasal spray version, also called the live attenuated influenza vaccine (LAIV), because it seemed to provide better protection.

ACIP reversed itself, however, in 2015 because of disappointing performance against the 2009 H1N1 virus. As with other vaccines, LAIV also didn't work well during the 2014-15 season against a drifted H3N2 strain.

Though the measure passed overwhelmingly with 13 for, 1 abstention, and 1 against, many ACIP members had reservations about their votes. During today's meeting, several experts raised concerns about how the vote would affect the upcoming season's immunization programs and the challenges explaining the new recommendation to the public.

...Members were swayed, though, by scientific findings showing low effectiveness over the past three seasons and opted not to adopt wording that would have allowed for use of LAIV if the injectable version wasn't available.

...During meeting presentations, experts said producers expect to make 171 million to 176 million doses of flu vaccine for the upcoming flu season, of which about 14 million doses (8%) are LAIV. Many providers have already ordered vaccine, leaving some scrambling to replace the inhaled doses they ordered, and the lack of inhaled vaccine will likely affect school-based flu vaccine programs, which reach 5% of schoolkids. LAIV accounts for about 55% of vaccine used in school-based programs.
