People over the age of 65 are at the most risk of contracting severe influenza. A new flu shot containing a booster has just been approved with hope of protecting senior citizens who are not fit for the traditional flu shot due to a poor immune system. The booster itself is meant to enhance your immune system when mixed with the virus, which allows the vaccine to have a better rate of success.
The booster contains an oil-in-water mixture that includes squalene, an oily nutrient produced by the liver, and some preservatives. When this mixture is added to vaccines, it increases the number of immune cells overall.
The Centers for Disease Control and Prevention states that anywhere from 3,000 to 49,000 people a year die from the flu, and usually most are over 65. This new vaccine has been around since 1997 and at this point is considered safe for use.
The vaccine will become available by next year in the United States.
