The nasal spray flu vaccine is back. It was not recommended for the past two years after it was found to lack efficacy. The Centers for Disease Control and Prevention said FluMist could return after it was reformulated by maker AstraZeneca to better fight the H1N1 strand of flu.

The nasal spray is approved for non-pregnant individuals ages 2 to 49. The nasal spray vaccine isn't recommended for children younger than 2 or people older than 49; pregnant women; people with a history of severe allergic reactions to eggs or any ingredients in the vaccine; people with weakened immune systems; or children with asthma.

While many parents opt for the nasal spray instead of the shot for their kids, the The American Academy of Pediatrics recommends using the injectable flu vaccine rather than the nasal mist.

The CDC recommends getting vaccinated before flu starting spreading. This year it may be a good idea to get vaccinated a little earlier as the flu is already circulating in some communities.

Symptoms of influenza include fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue.

You can catch the flu after someone who's infected coughs or sneezes and sends out airborne respiratory droplets, by skin to skin contact, saliva or by touching a contaminated surface.

The flu is treated primarily with rest and fluid to let the body fight the infection on its own. Over-the-counter anti-inflammatory pain relievers may help with symptoms. An annual vaccine can help prevent the flu and limit its complications.

The CDC says there will be between 163 million and 168 million doses of injectable vaccine on the market this year.
