Worried about catching the flu this season? There are many things you can do to prevent the spread of the flu—washing
your hands regularly, getting adequate sleep, maintaining a healthy diet and exercise routine—but one of the best is to make sure you get vaccinated.
Kenneth Fox, MD, Pediatrician at NorthShore, addresses some of the pervasive myths surrounding the flu and the flu shot to give you your best
shot for dodging the bug this season:
Myth: I got the flu shot and got the flu right away.
Fact: The flu shot is not 100 percent effective but it is effective. The vaccine reduces a person’s risk of developing significant symptoms by 60%.
Myth: The flu shot is effective immediately.
Fact: It takes a period of two weeks for the flu shot to take effect.
Myth: Only the elderly and young children are affected by the flu.
Fact: The elderly and children younger than two (as well as people with other underlying medical conditions such as asthma, heart disease, cerebral palsy, COPD, diabetes, kidney or liver disease) are at highest risk for flu complications. Those
with compromised immune systems are also at especially high risk. But, the flu can strike anyone. Some of the most serious cases can occur in people who were previously healthy.
Myth: People suffering from the flu should always go to the hospital.
Fact: Healthy people should take care of themselves at home: get plenty of rest, drink lots of fluids and take Tylenol or Advil. Be watchful of other health issues though. If you are suffering from labored breathing or dehydration, you should
go to the emergency room.
Myth: You should feed a cold and starve a fever.
Fact: Maintaining nutrition and staying hydrated is important when you are sick with the flu, so the answer is feed and feed.
Myth: Getting the flu shot once per season is always adequate.
Fact: One flu shot per season is adequate for almost everyone, with the exception of children under nine years old who should get two doses of flu vaccine (separated by four weeks) during the first flu season they are immunized.
Myth: Flu and cold symptoms are the same.
Fact: Flu symptoms include a fever, cough, congestion, chills, fatigue, body aches, and often sore throat and headache. Cold symptoms are fewer in number, much milder and last just a few days.
Myth: The flu lasts 24 hours.
Fact: Children are typically ill 7-10 days but can shed the virus a few days before their symptoms begin and up to 2 weeks after the start of symptoms. Adults are typically ill 5-7 days but shed the virus 1 day before symptoms begin and usually
up to 5 days after the start of symptoms. Some symptoms like fatigue may last for several weeks in kids and adults.
Myth: There is no way to protect yourself from the flu.
Fact: The flu vaccine is a safe and effective way to prevent the flu and to reduce the risk of its complications. Also, thorough and frequent hand washing, avoiding contact with contaminated surfaces, getting adequate sleep, nutrition and hydration
all reduce a person’s flu risks. Being watchful of complications and seeing your doctor if serious symptoms arise (like difficulty breathing and dehydration) reduce your risks of harm. Staying home when ill with the flu and covering your mouth when coughing
also reduces the risks of spread in the community.
It’s not too late to get vaccinated this flu season. Have you had your flu shot?
Every flu season is different but there’s one thing you can count on: there will be one. Flu season in the U.S. can
begin as early as October and continue into late May. Perhaps you’ve already noticed an uptick in coughing and sneezing on the train, in the office or at school, but it’s not too late to take action and keep your family happy and healthy throughout flu season.
