Type of medicine: vaccine
Generic and brand names: influenza vaccine, injection; Fluarix
This medicine is given by injection (a shot) to provide protection against the flu virus. The vaccine must be given each year to prevent infection during flu season. The flu vaccine is recommended for all people age 6 months of age and older. If vaccine supply is low, shots are given first to people who could have serious medical problems if they came down with the flu.
Several groups of people are at higher risk for getting the flu and should receive a flu shot every year, such as:
Before taking this medicine, tell your healthcare provider if you have ever had:
Tell your healthcare provider if you currently have a fever or an infection of any kind. Young children who get inactivated flu vaccine (flu shot) and pneumococcal vaccine at the same time may be at increased risk for seizures caused by fever. Talk with your healthcare provider about this.
If your child takes aspirin regularly, talk with your provider before your child receives this vaccine.
Females of childbearing age: Tell your healthcare provider if you are pregnant, plan to become pregnant, or are breast-feeding.
This medicine is given by a healthcare provider.
The flu vaccine becomes effective 2 to 4 weeks after you get the shot. You can get vaccinated any time during flu season. However, it is best to get the flu shot as soon as it is available, usually in September or October, of each year for full protection.
This medicine is approved for use in children 3 years of age and older, as well as adults.
Adults and older children need one dose of influenza vaccine each year. Children younger than 9 years of age may need 2 doses, at least 4 weeks apart, to be protected. Talk with your healthcare provider about this.
The flu vaccine reduces your risk of getting the flu, but may not completely protect you. You still have a small chance of getting the flu even after a flu shot. If you do get the flu, your symptoms should be less severe, and you are less likely to develop complications. The flu vaccine will not protect against colds or viruses other than the flu.
For a day or two after you get the vaccine, you may feel sore where you had the shot or have a mild fever, headache, or tiredness. If any of these side effects lasts longer than 2 days or if they become severe, contact your healthcare provider.
If you need emergency care, surgery, or dental work, tell the healthcare provider or dentist you have received this medicine.
Children may develop a fever after the shot. If the fever is high or lasts longer than 2 days, contact your healthcare provider.
