Flublok®: The Egg-Free Flu Vaccine

As most of you know by now, I am a full-time physician. This year the healthcare system I work for changed it’s flu vaccination policy. In the past, the flu vaccine had been voluntary but in 2014 it became 100% mandatory.

IMG_3185.PNGWhat??? I’ve never received a flu shot in the past. Why? Because I’m allergic to eggs!!! Is there an egg-free flu shot?? Yes, there is and it’s called Flublok®.

IMG_3220.JPGIn addition to being egg-free, Flublok® does not contain preservatives, including the mercury-containing thimerosal. It is designed to protect against the H1N1, H3N2, both A strains and one B strain of the influenza virus, and is approved for people between ages 18 and 49.

How is Flublok® different from other influenza vaccines?
Most influenza vaccines are made through an extremely complicated process that starts out with fertilized chicken eggs as a culture for the virus. This traditional method is extremely safe and effective; however, advanced technologies have arrived on the scene. Flublok® is the only licensed influenza vaccine on the market that does NOT use eggs, antibiotics, or live influenza virus in any part of the manufacturing process. The vaccine is made using a cutting edge, cell-based technology that is very similar to that used to create cervical cancer vaccines. The FDA has also referred to Flublok as “Revolutionary.” According to Jerry P. Weir, Ph.D., the director of the Division of Viral Products in the FDA’s Center for Biologics Evaluation and Research, Flublok® “is an important advance that will supplement egg-based vaccines.”

What are the benefits of Flublok®?
Flublok® is an incredibly pure, safe, and effective influenza vaccine option that offers the recipient numerous benefits:
-Triple strength
-No influenza virus
-No eggs
-No gelatin
-No antibiotics
-No formaldehyde
-No thimerosal or other preservatives
-No latex

How is Flublok® made?
Flublok® is made by taking the genetic information from one protein of the flu virus (the HA protein) and putting it into cultured cells that are grown in stainless steel tanks. These cells then make hundreds of copies of the HA protein, the small piece of the flu virus that is needed for immunity to develop. The proteins are then purified, and packaged into doses of Flublok® influenza vaccine. Each dose offers immunity against the three most commonly circulating virus strains each year, so that recipients receive optimum protection.

Should you get Flublok®?
Flublok® is approved for adults 18 years and older. According to the CDC, the single best way to prevent the flu is to get the flu shot each year. So, if you are 18 years of age or older, and would like to receive the a flu vaccine that is pure, safe, egg-free, thimerosal & preservative-free, this is the flu shot for you!

If you or someone you care about wants a pure, safe, and effective influenza vaccine or has an egg allergy, consider Flublok®.
