Here's why people do not get vaccinated against the flu and why you should

It is true that very young and very old are the most likely to die of the flu. However, that does not make everyone invincible.

The flu can wreak havoc on the body. Upper respiratory tract disease may cause fever, cough, sore throat, runny nose or stuffy nose, body aches, headache, chills, fatigue, and sometimes diarrhea and vomiting. according to the CDC.

This can lead to complications such as pneumonia, which can be serious. The combination of influenza and pneumonia was the eighth leading cause of death in 2016, killing 51,517 this year, according to the CDC.

Health researchers have also found increased risks of heart attack and stroke as people recover from the disease.

In addition, even if you are young and healthy, you can spread the flu to someone who is not. Apparently healthy adults might be able to infect other people one day before the onset of their symptoms and up to five to seven days after falling ill, according to the CDC.

"Often one of the most compelling arguments is that you are in good health, but what about grandmother or a little baby?" said Dr. Richard Webby, a member of the Infectious Diseases Department of the St. Jude Children's Research Hospital and the World Health Organization Vaccine Composition Team. "There is a chance that you are transmitting the virus to other high-risk people, and by vaccinating yourself, you may be protecting others as well."
