AstraZeneca’s FluMist® Quadrivalent (Influenza Vaccine Live, Intranasal) nasal-spray flu vaccine begins shipping for 2015-2016 season

Nearly 15 million doses will be distributed in the US to help protect eligible individuals 2 to 49 years of age against influenza

AstraZeneca began shipping its first doses of FluMist® Quadrivalent (Influenza Vaccine Live, Intranasal), developed by MedImmune, our global biologics research and development arm, for the 2015-2016 flu season today. FluMist Quadrivalent, the first and only needle-free, nasal spray flu vaccine approved by the Food and Drug Administration, helps protect against four influenza strains contained in the vaccine: two influenza A strains and two influenza B lineages.1,2

A needle-free, nasal spray option for eligible individuals 2 to 49 years of age, FluMist Quadrivalent is administered as a mist sprayed into the nose, where the influenza virus usually enters the body. People who have a severe allergy to eggs or other vaccine ingredients, anyone who has had life-threatening reactions to flu vaccines, and children or teens taking aspirin or products containing aspirin should not receive FluMist Quadrivalent. The most common side effects of FluMist Quadrivalent are runny or stuffy nose, sore throat, and fever over 100°F.1Please see Important Safety and Eligibility Information and accompanying full Prescribing Information, including Patient Information.

“The US Centers for Disease Control and Prevention (CDC) says the single best way to prevent influenza is to get an annual influenza vaccination,” said Chris Ambrose, Vice President, US Medical Affairs, Infectious Disease at AstraZeneca. “We are proud to continue our work with healthcare providers, retailers, and the public health community by providing eligible patients with FluMist Quadrivalent for the upcoming flu season.”3

The 2015-2016 flu season will be the third year that a quadrivalent influenza vaccine will be available in the US as a nasal spray.4 Unlike trivalent vaccines, quadrivalent vaccines include a second B strain to help provide additional protection against influenza B strains that may circulate.5

A study from a previous flu season found children ages 2 – 5 who received FluMist® (Influenza Vaccine Live, Intranasal) were about half as likely to get the flu compared to those who received the traditional flu shot.*1,5,6 Not all influenza vaccines are approved for all persons. Individuals should check with their healthcare provider regarding eligibility for FluMist Quadrivalent. FluMist Quadrivalent does not protect all individuals receiving the vaccine.

AstraZeneca is planning to produce and deliver nearly 15 million doses of FluMist Quadrivalent this influenza season, with product initially becoming available at the point of service in early September, followed by regular shipments to distributors throughout the end of the influenza season, as opposed to prior seasons when supply has been largely allocated during the season’s earlier months.

FluMist Quadrivalent will be available through private healthcare practices, public health departments, school-located vaccination programs, military bases, and select local and national retail pharmacies. Families can track where FluMist Quadrivalent is available in their local area via an online vaccine locator tool.

FluMist Quadrivalent is covered by most health insurance plans with immunization benefits; therefore, most patients who have health insurance for immunizations have coverage for FluMist Quadrivalent. People should consult their health insurance plan for more information.1
