FLUZONE® Quadrivalent is Formulated with These Four Strains:

Scientists at the World Health Organization (WHO) make predictions each year to determine which strains should be included in the annual seasonal influenza vaccine;1

however, it has been challenging to accurately predict which strains of influenza A and B will dominate. Over the past 15 flu seasons, the dominating circulating B strain was different in 7 of these
seasons than predicted by health authorities.3a,3b,3c,3d

Effective Against Four Different
Strains of the Flu2

FLUZONE® Quadrivalent vaccine is designed to help protect people six months of age and older against four different strains of the flu: two influenza A viruses and two influenza B viruses.2 Helping to protect against both influenza A and B viruses is important because both types are responsible for a substantial amount of flu-related hospitalizations and complications.4,5

Help Protect Your Children
From the Flu as Early as
Six Months of Age2

Children, especially those younger than five years of age, are at high risk for developing complications from the flu.6

FLUZONE® Quadrivalent vaccine provides protection against two, rather than one, of the strains of influenza B that may circulate. 1

For children 6-23 months
of age, NACI recommends that,
given the burden of influenza B
disease, quadrivalent influenza
vaccines should be used.

If quadrivalent influenza vaccines are not available, either unadjuvanted or adjuvanted trivalent influenza vaccines should be used.2

Current trivalent flu vaccines help protect against two influenza A viruses but only one influenza B virus.1

Depending on your age or your child’s age, different dosage forms of FLUZONE® vaccines are available.2 Talk to your health care provider about the best option for you or your child.

Helping to protect against two
influenza B viruses is important

Data shows that influenza B viruses are responsible for a substantial burden of flu-related hospitalizations and complications, especially in children.1 But for adults 65 years of age or older, consider FLUZONE® High-Dose vaccine, a three-strain flu vaccine specifically designed for seniors with four times the amount of antigens of our standard-dose flu shot, which has been shown to generate a stronger protection against the flu than our standard-dose flu vaccine1,7,8.
