Learn More About Flu Vaccinations
Every year, thousands of Australians receive a flu vaccination. Despite its incredible popularity, though, very few people are aware of the complex, involved process that is performed to create it.
If you have ever wondered how these vaccinations make their way to your local doctor’s office, continue to read as we have highlighted the key steps involved. Each year, this same process is followed; read on to learn more.
WHO Selects Top Virulent Strains -
Since influenza is a virus, it mutates every single year. The World Health Organization’s Global Influenza Surveillance Network selects the top three strains every year, usually during the fall months. These strains serve as the basis for that year’s flu vaccine.
Eggs’ Roles In Developing The Flu Vaccine -
Once the three virus strains are chosen, scientists get to work on developing the flu vaccine in earnest. They use fertilized chicken eggs to do this.
Viral Fragments Combined -
From the three virus strains harvested from the eggs, fragments are collected and combined. Incredibly, one egg is required for every dose of the influenza vaccine, meaning that millions and millions of eggs are used every single year.
Final Preparations Are Made -
Over the winter, the vaccine is tested rigorously to ensure its safety and its effectiveness. Time is of the essence during this period, since new flu viruses are being mutated all the time.
The Flu Vaccine Goes Public -
In September, the new flu vaccine for the year is shipped out all around the world. From Australia to North America to Europe, Asia and Africa, millions upon millions of doses are delivered.
