How effective is the flu vaccine?

The changing weather isn’t just a hint that winter is coming — it’s also an indicator that cold and flu season is upon us.

With that comes the calls for everyone to get vaccinated for this year’s strain of the influenza virus.

Gone are the days when the Spanish Flu killed upwards of 20 million people, but the flu virus remains dangerous for children, the elderly, and those with weakened immune systems.

A vaccine is created each year to combat what researchers believe to be the suspected strain of flu that will rear its ugly head this season.

The US Center for Disease Control’s data shows that the vaccine is generally 40-60% effective in preventing the flu virus in vaccinated individuals.
