When the flu season comes around each year, health officials recommend nearly everyone get vaccinated. One major exception is people with egg allergies, since the standard vaccine uses chicken eggs in its manufacturing process.
This year, many egg allergy sufferers have a flu vaccine option. Flublok, made without using eggs, was approved in January by the U.S. Food and Drug Administration, and the federal advisory committee on vaccinations in June unanimously recommended its use for ages 18 through 49.
Because its manufacturing process doesn’t have to wait for incubation in eggs, Flublok also could be particularly important for quick changes in the vaccine in years when new strains of flu hit. But for now, it’s egg allergy sufferers who are most likely to benefit from the new vaccine.
Keep that in mind when the new vaccine begins to arrive in late summer.
