A new vaccine has been approved by the Food and Drug Administration (FDA) for those who have allergic reactions to eggs.

Multiple reports say the Influenza vaccine called FluBlok has been approved for people 18 to 49 who experience serious reactions to any vaccine components that contain certain antibiotics, egg proteins or latex. The new vaccine has been officially added to 2013-2014 flu recommendations for adults, but was not approved for children under 18.

According to Medpage.com, "Flublok is made using recombinant DNA technology and contains hemagglutinin produced in an insect cell line."

Before the new vaccine, people with history of hives upon exposure to egg were recommended to get "inactivated influenza vaccine," followed by an observation period of at least 30 minutes after administration.

The Advisory Committee on Immunization Practices (ACIP), after a unanimous vote, also recommended Flublok (RIV3) be listed as an alternative in case of extreme reactions.

"A reference to RIV3 also will be made in added language referring to people who do not have a history of egg allergy but who may be at risk based on previously performed allergy testing," Medpage.com reported. "In that case, 'consultation with a physician with expertise in the management of allergic conditions should be obtained prior to vaccination' or, if age appropriate, RIV3 can be given."

During ACIP's last meeting in February, the committee also approved four additional new flu vaccines for the 2013-2014 season.  According to reports, a FDA approved vaccine called Sanofi Pasteur's Fluzone Quadrivalent was suggested for children younger than 2.

About 1 in 66 children have egg allergies, however most will outgrow them.

According to reports, Flublok's safety evaluation was conducted in a study of about 2,500 people who were injected with the new flu vaccine. The most common side effects included pain at the site of injection, headache, fatigue and muscle aches.
