ACIP Votes in Favor of Intransal Flu Vaccine Flumist Quadrivalent

During the 2015 season, CDC researchers a found that FluMist was less effective against all flu strains, in large part because it didn't seem to work at all against the H1N1 strain of the flu virus, also known as swine flu.

AstraZeneca announced that ACIP, an advisory panel of the Centers for Disease Control and Prevention (CDC), has voted in favor of a renewed recommendation for the use of the company's FluMist Quadrivalent (influenza vaccine live, intranasal) for the 2018-2019 season.

The vaccine will still be subject to annual strain approval by the FDA for next season.

The advisory committee that decides which vaccines are available agreed.

FluMist, the only needle-free flu vaccine on the market, won a lukewarm recommendation from federal vaccine advisers Wednesday. The vaccine has remained recommended for use and available in Canada and the European Union. It is approved for ages 2 through 49.

After the tragedy, Grande had organised the 'One Love' concert, with a line-up that included bands Take That and Coldplay. Now, just hours before the show is about to begin, the singer has reportedly cancelled her appearance entirely.

All eyes are now on the reformulated FluMist's effectiveness, as experts have anxious that poor effectiveness will turn people off flu vaccines.

According to an NBC News report, some ACIP members are anxious that an ineffective FluMist will hurt public perceptions, but others argue that the lack of a needle-free option turns kids off getting vaccinated.

All flu vaccines are a cocktail, made using three or four strains of the most common circulating flu viruses. But real-world efficacy is a far better measure of how well a vaccine actually works than lab tests, and we haven't seen another flu season dominated by H1N1 since the 2009-2010 season (though there's bound to be one in the future).

Overall, there have been 4,699 flu-related hospitalizations during the current season, which is an increase of more than 1,000 from last year's total, and the most during the last five years.

Two U.S. doctors said the new research appears to have swayed the panel.
