Fluzone High-Dose is a flu vaccine for people age 65 and older that’s given by injection. Like other flu vaccines, Fluzone High-Dose is made up of the three flu strains most likely to cause the flu during the upcoming flu season. A new vaccine called Fluzone High-Dose Quadrivalent that is made up of four flu strains has been app<\/a>roved for people age 65 and older.\n <\/p>\n

The high-dose vaccines, however, contain four times as much flu virus antigen – the part of the vaccine that stimulates the immune system – as regular Fluzone and other standard flu vaccines. This can give older people a higher immune system response against the flu.<\/p>\n

Why is it needed?<\/b><\/p>\n

Some older adults may have weaker immune systems, which can lead them to be less protected after a regular flu vaccine. In response to a regular flu shot, older people produce 50% to 75% fewer antibodies, which protect against the vaccine antigens, than do younger adults.<\/p>\n

Studies have found higher antibody levels in older adults who received high-dose flu vaccines than in those who received standard flu vaccines.<\/p>\n

In addition, one study found almost 25% fewer cases of influenza in adults age 65 and older who took the high-dose vaccine compared with those who took the standard-dose vaccine.<\/p>\n

Are there side effects?<\/b><\/p>\n

In a large study comparing high-dose and standard-dose flu vaccines, those who received the high-dose vaccine were more likely to develop side effects during the week after getting the vaccine. Side effects included a fever and soreness at the injection site.<\/p>\n

More research needed<\/b><\/p>\n

People age 65 and older have the highest risks of flu complications. Protecting this group from the flu is especially important.<\/p>\n

The U.S. Food and Drug Administration accelerated its approval of Fluzone High-Dose on the condition that studies will continue to evaluate the new vaccine’s effect on seasonal flu outcomes, such as flu cases or its complications, in older adults.<\/p>\n

If Fluzone High-Dose turns out to have better outcomes than the regular flu vaccine over time, the high-dose vaccine may become the vaccine of choice for older adults. For now, it’s most important for everyone to get the annual seasonal flu vaccine.\n <\/p>\n\n
