What is the Nasal-Spray Flu Vaccine and how it works?

The Nasal-Spray Flu Vaccine is a vaccine for influenza that provides protection against pandemic or seasonal influenza outbreaks. The Nasal-Spray Flu Vaccine is also known as the Live Attenuated Influenza Vaccine (LAIV) and it successfully reduces the chance of children being infected with influenza by 92% as has been proven by a study. A study including the effects of this vaccine on adults has also proven to lead to positive repercussions. This influenza vaccine is not only effective but it is COST effective as well. While the vaccine can be administered by using an injection, it is possible to administer it as a nasal spray, which is more suitable for non-pregnant and healthy people who need protection from the flu virus and are aged between 2 to 49 years old. Since this vaccine is a live virus, it is better for the person who receives the vaccine to not come in close contact with people with weakened immune systems.

The LAIV FluMist is one such very effective Nasal-Spray flu vaccine. However, this vaccine may have side effects, especially on children, These effects may include headache, runny nose, vomiting, wheezing, fever and muscle aches. In the case of adults, coughing, headache, runny nose and sore throat are a few common side effects of the vaccine, although developing a fever is very rare.
