Bad news for people 2 through 49 years of age: it’s back to the needle for your annual flu vaccine.
CDC’s Advisory Committee on Immunization Practices (ACIP) advises the CDC on immunization matters. At their last meeting, they advised against using the nasal spray flu vaccine during the 2016-2017 flu season.
The live, attenuated influenza vaccine (LAIV) is one we all love because it’s a simple spray up the nose. But, the data from the last three years say the spray vaccine’s effectiveness isn’t great. It just doesn’t seem to work that well.
When the nasal spray vaccine was first licensed, data showed it to be as effective as the vaccine given in a shot. Researchers have yet to figure out why the nasal spray isn’t currently protecting people from flu.
The ACIP made its recommendation, but the CDC’s director has to review and approve it before it becomes an official policy.
The final recommendation should be published in August or September 2016.
