A study by researchers in May shows evidence that nasal spray flu vaccine is ineffective and offers the least protection in 2016. The research reported in May is in contrast to the previous policy which claimed the effectiveness of the mist flu vaccine.

Nasal spray vaccine was approved in 2003

The first nasal spray vaccine use was done in 2003 when FDA gave a green light. The mist works to stimulate the body's immune system and many studies claimed that it has proven to work better than the traditional injectable vaccine.

Apart from that, pediatricians have been using the nasal spray vaccine for years because it is more kid-friendly. Now, the updated policy has changed the game.

Flu shot is more effective than nasal spray for flu vaccine

The traditional flu shot is in fact, more effective. Dr. William Schaffner, an expert in infectious disease spoke to CNN and said that the nasal spray flu vaccine performs poorly.

In the Recommendations of the Advisory Committee on Immunization Practices published by CDC, there has been a change made in the policy. It states that FluMist, a nasal spray flu vaccine, should 'not be used during the 2016-17 season'.

Why nasal spray flu vaccine is not working? CDC still can't figure out

Although the reason of ineffective nasal spray flu vaccine is unknown, experts want an immediate protection against flu especially for the children. However, the research has shown that traditional flu shot delivers higher level of protection than nasal spray can. It would take more time for researchers to find the causes but for now, CDC recommends the inactivated flu shot for better protection against flu.
