INFLUENZA AND YOUR IMMUNE SYSTEM
It has been recognized for many years now that the immune system weakens as we age, reducing our body’s ability to fight infection, no matter how fit we may be.2,3 That’s why people aged 65 and over are more at risk of developing serious complications from an influenza infection.3,4 Complications can include pneumonia, serious cardiovascular events such as heart attack or stroke, and worsening of underlying chronic illnesses (heart, pulmonary and metabolic diseases like diabetes).5,6

OLDER ADULTS CAN BE AT A GREATER RISK OF INFLUENZA COMPLICATIONS
If you are 65 years and older, you are at an increased risk to suffer from severe complications of an influenza infection.3 2 out of 3 influenza related hospitalisations occurred among people 65 years and older.7 ONLY 1 in 3 adults above 70 years hospitalised for an acute illness, such as influenza, fully recovered after one year.8 Vaccination is the most effective way to protect against influenza and reduce the risk of its complications.9 Older adults (65 years and above) are recommended to receive an influenza vaccination every year to stay protected.3,9 Influenza vaccines are well tolerated. As with any vaccines, side effects can occur but these are generally mild.10 [video width="1920" height="1080" mp4="http://dbank.medinformer.co.za/wp-content/uploads/2023/03/19468-5-things-Vaxigrip-December-5.mp4"][/video]

- Reduce illness from flu
- Reduce the need to visit the doctor
- Reduce the severity of illness in people who get vaccinated but still get sick

MYTHS
Myth: I don’t have to get the flu vaccine every year. Fact: Flu viruses change constantly. The flu vaccine is updated annually to protect against the viruses that are expected to be most common during each flu season9 Flu vaccines only work in our bodies for a certain amount of time. For both these reasons you must be vaccinated every year.9,10 Myth: I got the flu vaccine and still got sick so it does not work. Fact: The vaccine contains inactive viruses so it cannot make you sick. Sometimes you might get other viruses that are circulating that could be mistaken for flu.8 Myth: I am pregnant, so it is not safe for me to get the flu vaccine. Fact: Pregnant women are at high risk for developing complicated flu. The flu vaccine can be used at any stage of pregnancy and protects the baby against flu infection for several months after it is born.2,8
