In general, vaccines are one of the best tools in medicine: The World Health Organization reports that 2 million to 3 million lives are saved every year thanks to vaccines.
Vaccines also have lower rates of complication than most medications. In fact, the Centers for Disease Control and Prevention estimates that there is about a one in 1 million chance that someone will have a severe reaction to common vaccines like MMR (aka, measles, mumps, rubella) or hepatitis B.
What about flu vaccine safety? CDC recently released a video about the safety of the influenza vaccine that answers a lot of common questions, such as safety of the flu shot for young children, pregnant women and people with egg allergies.
(Spoiler alert: Yes, the flu shot is safe for almost everyone!)
