I read a post on Bill Gates’ blog about polio. It talks about how vaccines helped us survive the disease and easily walk. Thousands of people were infected with polio during time and lost ability to walk or even stand. The suggested cure for polio was a metal tank, an iron lung, a mechanical respirator.

Polio attacks the body’s nervous system, crippling patients. In the worst cases, the disease paralyzes their respiratory muscles and makes it difficult for them to breathe, sometimes resulting in death.

Using changes in air pressure, the iron lung pulls air in and out of a patient’s lungs, allowing them to breathe and stay alive. During the height of the polio epidemic in the U.S. in the 1940s and 1950s, rows of iron lungs filled hospital wards to treat thousands of polio patients, most of them children.

Today, we don’t need iron lungs anymore as there’s an effective vaccine for it. Every person now gets vaccinated against polio and, since 1988, the world decided to eradicate the disease. Polio cases dropped since then by nearly 100 percent.

Before vaccines, more than 350 thousand people were infected in a year, facing horrible consequences and difficulties in their life but now there’s fewer than 200 cases yearly only in two countries, Afghanistan and Pakistan, in which extremists force people to avoid vaccines using religious propaganda.

Today, some people are spreading false information about vaccines claiming a vaccine is a conspiracy to turn people to something other than a human or vaccines are tools to impose surveillance on people. Of course some vaccines are not effective, we’ve seen them, but to induce that vaccines in general are harming people, that makes no sense.

I’ve seen the effect of vaccines on people. From influenza to polio to tetanus and Meningococcal vaccines, I’ve seen how they help people live and be healthy and I’ve seen how without them people are harmed and face difficulties, even death.

I’m not yet vaccinated against coronavirus (COVID-19) but I will be when it’s time for people my age. My grandparents and some relatives are vaccinated. They didn’t face any aftereffects. One of my relatives was vaccinated while his family were not, and I’ve seen how all of his family members got sick but he were OK. All of them recovered, happily.

Vaccines are results of scientific works, and I believe in science. People say science is always changing and is not reliable but that’s one reason I support it. Science always changes and gets updated for better. That’s why I rely on it. When it comes to vaccines, science is proven to be always working to get better, from iron lungs to polio vaccines, it’s always working to help people.
