![]() ![]() ![]() When will we know if the flu shots are a "good match"? All vaccines should be given in settings where allergic reactions can be recognized and treated quickly, according to the new guidance. "Egg allergy alone necessitates no additional safety measures for influenza vaccination beyond those recommended for any recipient of any vaccine, regardless of severity of previous reaction to egg," the committee advised. Why is the flu shot less effective than other vaccines? ![]() 2 types of flu viruses may have gone extinct The worst epidemics and pandemics in history This advice is based on new guidance from a CDC vaccine advisory committee that recently reviewed the available safety data. People with egg allergies can receive any flu shot, egg-based or otherwise, and they don't need a special doctor's appointment to do so, the CDC says. Which flu shot should people with egg allergies get? The high-dose shot is called Fluzone High-Dose Quadrivalent and the adjuvanted vaccine is called Fluad Quadrivalent. Along with the recombinant shot, these vaccines are especially recommended for older people because they're more protective in this age group than the standard-dose vaccines. High-dose and adjuvanted flu shots: One high-dose flu vaccine and one adjuvanted vaccine, which contains an added ingredient to rev up the immune system, are approved for use in people 65 and older. This vaccine is approved for most people ages 2 to 49, but it's not approved for people who are pregnant, have weakened immune systems or have certain other conditions. It's a live attenuated vaccine, meaning it contains weakened flu viruses that can't cause disease but have not been "killed," like the viruses in inactivated shots. Nasal spray: The one vaccine that's available as a nasal spray is called FluMist Quadrivalent. It's one of three vaccine options especially recommended to people 65 years and older. There is one recombinant vaccine available called Flublok Quadrivalent, and it's approved for use in people ages 18 and older. Recombinant flu shots: Recombinant flu shots are made using " recombinant technology," which involves using flu virus genetic material to make a protein found on the virus' surface - hemagglutinin (HA). They are approved for use in people ages 6 months and older. Standard-dose, inactivated flu shots: Inactivated flu shots contain influenza viruses that have been "killed" so they can no longer infect cells. Speak to a doctor, pharmacist or other health care professional if you have questions about which flu shot is best for you. All the vaccines guard against four influenza virus subtypes: A(H1N1), A(H3N2), a Yamagata lineage influenza B virus and a Victoria lineage influenza B virus. There are nine different flu vaccines available this season, including eight that are injected and one that's sprayed up the nose. (Image credit: Getty Images) What types of flu shots are available? The nasal spray is one of nine different flu vaccines available. Related: The flu shot isn't that effective. Although it's ideal to get your flu shot early in the season, it's better to get one late than not at all. In a typical season, flu cases start to ramp up in late October and peak between December and February. Most people should get a flu shot in September or October, before the flu starts circulating widely, the CDC advises. Note that some children ages 6 months to 8 years are recommended to get two doses of vaccine. Flu shots are especially important for people who are older than 65, younger than 2, pregnant, or have very recently given birth, the CDC states. People with a history of Guillain-Barré Syndrome, a rare paralyzing condition in which the immune system attacks the nerves, should also consult a doctor before getting a flu shot.īut everyone else can assume they should get a shot. People who have had a severe allergic reaction to a flu vaccine should not get the same type of vaccine again and should consult a doctor about whether to get a different shot, the CDC says. These potentially allergy-triggering ingredients include gelatin, which is used as a stabilizer in some vaccines, and certain antibiotics, which prevent bacterial contamination during vaccine manufacturing but can linger in very small quantities in some shots post-production, according to the Children's Hospital of Philadelphia. These exceptions apply to people with severe, life-threatening allergies to specific vaccine ingredients. Everyone ages 6 months and older should get a flu shot every season, with rare exceptions, the Centers for Disease Control and Prevention (CDC) recommends. ![]()
