Dr. Anne Pham-Huy, a pediatric infectious disease specialist at CHEO who chairs Immunize Canada, spends a lot of time talking with her patients and their families about vaccines. She often hears misconceptions about influenza and the vaccine that protects against it.

It’s “just the flu”: Flu can be serious, even deadly, especially in the elderly, the very young and those at high risk, but also in otherwise healthy people. “It can definitely be a severe disease, as we have seen. Some parents will say it’s just influenza, but it can affect healthy children. It is worse in children under five or those with medical conditions, but it potentially impacts anyone,” said Pham-Huy. Classic influenza, she said, “feels like you have been hit by a bus” and can lead to serious complications.

You can get the flu from the flu shot: Pham-Huy said she often hears that from patients, and emphasizes that it is not true. “The injectable flu vaccine is made of inactivated virus. It is 100 per cent impossible to get flu from the flu shot.”

It is not a perfect match so there is no sense getting it: Pham-Huy says the influenza vaccine protects against three strains of flu — two influenza A and one influenza B. It is a bit of a mismatch with one of the influenza A strains, which means the vaccine won’t be 100 per cent effective against it, but it will still offer protection even against the mismatched strain.

It is too late to get vaccinated because the flu is out there: It is not too late, said Pham-Huy. Although it generally takes two weeks to be fully protected, there is still time to get vaccinated and be protected during the busy holiday period when people are gathering in groups. “There are still benefits.”

Influenza is not the “stomach flu”. Families sometimes confuse the two, said Pham-Huy and then believe they got the flu after having the flu shot. What is sometimes called “stomach flu” is a gastrointestinal bug that can also be highly contagious.

Only the elderly need to get it: In fact, children under five are also at high risk for flu-related complications as well as people with immune compromise or other conditions that put them at higher risk. But the three flu-related deaths in Eastern Ontario were in children over the age of five, a group representing a large proportion of flu cases this season. Even healthy people can have serious outcomes from the flu, said Pham-Huy.
