Like any medical intervention, vaccinations can carry some risk so itís important to know whatís true and whatís not to make an informed decision. Letís dispel some of the myths to understand why the flu shot can help, even when youíre healthy.
Myth 1: The flu shot gave me the flu
The flu vaccine contains inactivated viral proteins so it is impossible for these parts to cause the flu. If you had the vaccine and got sick within the first couple of weeks, it is probably because the vaccine had not yet triggered an immune response. It takes about two weeks for the vaccine to become effective.
Myth 2: I had the flu shot but I still got the flu
The effectiveness of the flu shot depends upon how well the vaccine is matched to the circulating strain of the season. In general, the flu shot is considered 70 to 90 per cent effective against the most common strains. There are also other viruses that can cause colds and flu-like illnesses, which may not be prevented by the flu shot.
Myth 3: Iím pregnant and itís not safe to be vaccinated
While pregnant women are not more likely to get the flu, they have a lower immune response and as such are at a higher risk of developing complications such as pneumonia, bronchitis and the need for hospitalization. This is especially relevant for pregnant women in their second and third trimesters and up to six weeks post-delivery. It has also been found that infants whose mothers had been immunized in pregnancy also had reduced rates of influenza in comparison to those born to moms who were not vaccinated. So youíre not only protecting yourself by getting vaccinated when youíre pregnant but also potentially protecting your child as well.
Myth 4: Iím healthy, I donít need the flu shot
Even if youíre healthy, you can still get the flu and feel pretty miserable. Also, you can pass it on to others around you who may be more prone to the severe effects of the flu. If you have contact with anyone in one of the high risk groups (those over 65, pregnant women, children between six months to two years old, people with chronic medical illnesses or who are immunocompromised), consider getting the shot to not only protect yourself but more so to protect your loved ones and others at risk.
Myth 5: I had the flu shot last year so Iím going to skip out this year as Iím probably still protected
There are different circulating strains of the virus every year. So your previous vaccination may not fully protect you against this yearís particular strain.
Ultimately, the decision to get the flu shot will depend upon your personal wishes, your level of health and the health of those around you. For most, the benefit will greatly outweigh the risk of the vaccine so discuss with your family doctor and make an informed choice that is right for you.

Comment by me on 31st October 2013
I have been looking and reading a great deal online about the flu shot. And I have found that autism has gone up 75% since they started giving out flu shots. There are many people coming forward about what is in these shots. I wish everyone to find the truth for them selves. My findings made me wonder what is the true reason for these shots? And free even. HUH.
