How Long Do Flu Shots Last?

What are Flu shots and Why is it important?


Flu shots are often known as influenza vaccines that  provide protection against the influenza viruses that are expected to be most prevalent throughout the flu season. Most flu shots are administered using a needle typically in the arm. The flu shot is the best option to defend against the flu. The Government of Canada recommends that the flu shots should be taken by almost everyone who is 6 months of age or older.


The influenza vaccine reduces the severity of flu-related complications and the chance of becoming very ill.  By getting vaccinated, you not only protect yourself, but also people around you, as the likelihood of spreading the illness reduces. As a result, the demand on medical facilities during the virus season is reduced.  





Furthermore, taking the flu shot reduces the likelihood of contracting both the flu and other respiratory viruses at the same time.


The effectiveness of Flu shot


Flu shots aid in preventing the main types of flu viruses, but there is still a potential that you may get the illness. According to the findings the flu vaccine typically takes 10 to 14 days to take effect.  The vaccine often reduces the likelihood that the flu will spread among the general population by 40% to 60% when the strains are well-matched. You cannot avoid getting sick even if you get the flu shot as it will only protect you from influenza, not from other illnesses.


How long does a flu shot last? Typically, the effects of the flu shot or vaccine only deal with one flu season, which lasts for around six months. You require one every year in part because of that.
