  • 3 percent of children and 0.
  • Researchers often test the relationship between different flu strains, or how well infection or vaccination to one strain protects you from infection with another, in lab animals like ferrets.
  • Second, depending on the strain of the flu virus that you are exposed to, you could still get the flu even if you received the vaccine.
  • “The process is messy,” and it’s impossible for something retooled each year to be risk-free.

Myth #8: Healthy people don’t die from the flu

Osteholm, PhD, MPH, said the findings further complicate the already difficult challenge of framing flu vaccination recommendations. With many vaccines, an additional dose or two boosts the levels of antibodies in a person’s body. 10 best ginger shots for your immune system, finally, I’m ready to share my juicer recipe for these healthy Ginger Turmeric immune-boosting energy shots.
