The Science Behind Flu Vaccination: How It Works and Why It's Effective
The Science Behind Flu Vaccination |
When a flu vaccine is administered, it prompts the immune system to produce antibodies and memory cells. These antibodies recognize and bind to the flu virus, preventing it from infecting the body's cells. Memory cells help the immune system respond quickly to future exposures, providing lasting protection.
Types Of Flu Vaccines
There are different types of flu vaccines available, including:
❖ The inactivated flu vaccine contains killed flu viruses and is administered through injection. It is suitable for almost everyone, including those with weakened immune systems.
❖ The live attenuated flu vaccine contains weakened flu viruses and is administered as a nasal spray. It is generally recommended for healthy individuals aged 2 to 49 years.
Seasonal Flu Strain Selection
Experts predict yearly the flu strains likely
to circulate during the upcoming flu season. The flu vaccine is formulated to
include these specific strains, offering the best possible protection against
the most prevalent variants.
The flu vaccine can be administered by health care professionals, usually in clinics, pharmacies, or medical centers. It involves a quick and relatively painless injection or a nasal spray.
Effectiveness And Duration Of Protection
While the flu vaccine is not 100% foolproof, it significantly reduces the risk of getting the flu. Its effectiveness may vary yearly, depending on the match between the vaccine and the circulating flu strains. Nonetheless, even if you still get infected, the vaccine can make your symptoms milder and reduce the risk of complications.
