How do you prevent the flu?
Vaccination is the only active way to prevent and control influenza. It can prevent the flu in 70 per cent to 90 percent of young, healthy adults. You can still get the flu after having a flu vaccine but you will be far less sick than someone who has not received the vaccine. The vaccine reduces the severity of the symptoms and protects you from other viruses that sometimes feel like the flu.
Different types of flu vaccines have been available and used for more than 60 years. The difficult aspect of vaccine development is that the influenza viruses are constantly changing, so that the vaccines must also be changed annually to target the most recent circulating flu viruses. Scientists need about four months to develop a new vaccine that protects against a new virus.
There is no single vaccine that can be used to protect you from flu forever. While flu viruses can become resistant to antiviral drugs, they have not yet developed resistance to flu vaccines. Last winter in the USA, the influenza A (H3H2) virus was the predominant flu virus and it caused a more severe flu season.
Because the flu vaccine is only effective for one year and viruses vary from year to year, you should have a flu shot every year. Immunity does not develop immediately after your vaccination. The flu vaccine takes about 14 days to provide its greatest protection. Ask your doctor about getting vaccinated before the flu season arrives. Here in Australia, the vaccine is usually available from March each year.
If you’re not in one of the groups recommended to get the flu shot you still choose to be immunized. Your GP will write a prescription which will cost whatever the pharmacist charges. This year, US health authorities are recommending that all children aged six months to 18 years receive an annual influenza vaccination. These recommendations have nit yet been introduced in Australia. You can still ask your doctor for advice.
Our three kids already got the shots but we parents not yet so I guess by this month we can have it for prevention.
