Influenza has been around for hundreds of years. What we know now as the flu is nothing more than a mere virus, something that gives us a headache and cough for a couple of days. But before vaccines, it was much, much worse.

In 1918 there was a deadly flu pandemic, known as the Spanish flu. It infected 500 Million people, and killed 50-100 million, 3% of the population, making it one of the deadliest natural disasters in history. the strain eventually became less lethal after almost 3 years of deaths.

In 1933, 2 doctors discovered the flu was actually caused by a virus. In 1938, Jonas Salk and Thomas Francis developed the first vaccine against flu viruses. This first flu vaccine was used to protect the U.S. military forces against the flu during World War II. Dr. Salk also used this vaccine to create the polio vaccine later in 1952.

How it works: Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with the viruses that are in the vaccine. The seasonal flu vaccine protects against the influenza viruses that research indicates will be most common during the upcoming season There is no live flu virus in flu shots. They cannot cause the flu. The shot contains killed(inactivated) flu virus

what the disease does to your body: Anatomy: fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue Physiology: caused by a virus infecting the respiratory system, meaning your nose, throat, bronchial tubes, and lungs

The spiked red line is influenza. You can see the deaths went down 500,000 after the vaccine.

Statement: Clearly, vaccines play a major role in helping our bodies kill virus's. The flu has become a head cold now, instead of a pandemic that kills millions of people. I think vaccines are an important way to help our bodies attack what is trying to hurt us.
