It’s Flu “shot” season but thankfully not every vaccine hurts going in. This year your child may be offered either the “flu shot” or the flu nasal spray vaccine (ouchless!). This year most nurses and docs will encourage young children to get a nasal flu spray over the shot as recent data has found the nasal flu vaccine protects younger children better. Every year the flu vaccine is created to protect against influenza viruses predicted to spread and circulate in North America. We need the shot every year for two main reasons:
- Typically, different influenza virus circulate around the world from year to year. Over 100 international centers maintain year-round surveillance to determine and predict which strain will cause human infections. The information is used to forecast the recipe for the vaccine here at home. This year the strains (types) of influenza in the shot and nasal spray are the same as last year (2013-2014).
- Protection Fades. When you get a flu vaccine you stimulate the immune system to create protection against the strains of the virus in the vaccine. That immunity (the antibodies that are created) tends to fade and wane in your bloodstream after about 6-12 months. Therefore, even if you got the flu vaccine last year you really want your family to have it again this year so it protects you through the winter influenza season which can continue late into the springtime but tends to peak in February or March.
The flu vaccine contains either three (trivalent) or four (quadrivalent) strains of influenza. There is no official recommendation for one over the other. Flu vaccine is recommended for all children over 6 months of age who have no contraindication to the vaccine.
Worth noting: If the thought of needles deters you from getting the vaccine for your child or your family, Live Attenuated Influenza Vaccine (LAIV), a nasal spray, is a great option for those age 2 to 49 years. In fact, there’s data to suggest the nasal flu vaccine is more effective in protecting children from influenza in young childhood. Recommendations this year include a push to have children between 2 and 8 years of age immunized with the nasal spray whenever possible. If the nasal isn’t available, the shot should be given — no reason to wait.
About 20,000 children younger than 5 years old are hospitalized from flu every year — form CDC “Which Flu Vaccine Should Children 2 to 8 Years Old Get?”
