• “Even if I get flu vaccine, I can still get a mild case of the flu.” TRUE. Flu vaccine protects most people from the flu. A person who receives flu vaccine can get the flu but will be far less sick than someone who has flu and has not received flu vaccine. Flu vaccine does not protect you from other viruses that sometimes feel like the flu.
• “The side-effects are worse than the flu.” FALSE. The worst side-effect you’re likely to get with injectable vaccine is a sore arm. The nasal-spray flu vaccine might cause nasal congestion, runny nose, sore throat, or cough. The risk of allergic reaction to flu vaccine is far less than the risk of severe complications from flu itself.
• “Not everyone can take flu vaccine.” TRUE. You might not be able to get this protection if you are allergic to eggs (used in making the injectable vaccine), are very sick with a high fever, or have had a severe reaction to the flu vaccine in the past.
• “Only older people need flu vaccine.” FALSE. Adults and children with conditions like asthma, diabetes, heart disease, and kidney disease need to get flu vaccine. And people who are active and healthy can also benefit from the protection the flu vaccine offers.
• “You must get a flu vaccine before December.” FALSE. Flu vaccine can be given before or during the flu season. While the best time to get flu vaccine is October or November, getting vaccinated in December or later can still protect you against the flu.
REACTIONS: SHOTS or SPRAY? From the CDC’s website (www.vaccines.ashastd.org): The flu shot uses an inactivated or “killed” vaccine. This vaccine can’t give you the flu. However, flu vaccine, like other vaccines, can occasionally cause a reaction. Feeling some response to the shot is not unusual. The vaccine acts to stimulate your immune system and prepare you to resist infection. You may feel your body's protective activity through mild symptoms. Also, some people may experience symptoms of mild sickness after getting a flu shot, but these symptoms are not necessarily connected to the shot. If you do experience a reaction to the flu shot, it is usually local and mild — redness, soreness, and swelling at the site of the injection. Usually if you have this kind of reaction you find that it doesn't interfere with normal daily activity and does not make you feel sick. Fever and more generalized aches and pains can occur but are even less likely; those who are receiving the vaccine for the first time ever are most likely to have this type of reaction. You feel the symptoms, if any, within a few hours of the injection. The symptoms typically cause discomfort, not sickness, and last for a day or two.
The nasal-spray flu vaccine may cause nasal congestion, runny nose, sore throat, and cough — symptoms of a cold. Mild reactions to the nasal mist vaccine are not unexpected and should be brief.
Treating a Mild Reaction To treat either of these mild reactions to a flu shot, use over-the-counter medication only for the symptoms you have (fever, swelling, nasal congestion, cough, and aches and pains). Do not give aspirin to children; use another medication to relieve their fever or aches and pains. If fever is high or symptoms persist or are severe, talk to your doctor or healthcare professional.
