What do you think will be the role for Flublok which is being marketed for egg allergic people, in light of the recent reports that regular flu vaccine can be given to egg allergic people?

A:

Thank you for your inquiry.

Flublok, as you know, is a trivalent influenza vaccine that has been approved by the FDA for use in adults 18 to 49 years of age. According to the CDC website, Flublok’s potential benefit is that the “manufacturing process has the potential for faster startup of vaccine manufacturing, which can be useful in the event of a pandemic or vaccine supply shortage, mainly because it is not dependent on an egg supply or limited by the selection of strains that are adapted for growth in eggs.”

Thus, as you noted, Flublok, would be safe in egg allergic individuals. But, unfortunately, there is no way to predict with any accuracy predict what its role would be in the future. I think the answer to your question will only unfold over time.

Thank you again for your inquiry and we hope this response is helpful to you.

Sincerely,
Phil Lieberman, M.D.
