Gen X and younger generations in the developed world are medically spoiled - and that’s a good thing. Most of us grew up without losing siblings or classmates to smallpox, measles, polio, tuberculosis, scarlet fever, or flu. But our parents and grandparents did.
I only recently learned that my father had a brother who died before his first birthday from a febrile infectious illness. My mother lost a classmate to polio in primary school. She studied alongside a man blinded by measles in childhood and a woman who lost her hearing the same way.
My grandfather’s older brother died as an infant during an influenza outbreak.
That history is why families used to have many children: statistically, many would not survive.
In 1800, nearly half of all children died before the age of five.
By 2020, that figure had fallen to a tiny fraction. Improved sanitation and nutrition played a role. Advances in medicine played a role. But vaccines played the greatest role.
Are vaccines completely risk-free? No. But neither is crossing the road; but we still do it every day, because the benefit far outweighs the risk.
No medical treatment is 100% safe: not aspirin, not antibiotics, not surgery.
That’s why vaccines come with detailed safety data based on studies involving thousands of people. Most side effects are mild-fever, headache, fatigue, rash.
Serious reactions are rare.
And the evidence is overwhelming: vaccines are far safer than the diseases they prevent.
I work in a hospital and receive multiple vaccines regularly. As a child, I had the full routine schedule available at the time: MMR, Hepatitis B, DTP, and polio. There was no chickenpox vaccine then, so I caught it at age six. The doctor said I was lucky-it’s far more dangerous in adults; but it didn’t feel lucky.
I was feverish, miserable, and unbearably itchy. I recovered, but I would never wish that experience on a child, let alone the far more devastating illnesses vaccines now prevent.
Except we desire to return to the era where children barely survive childhood due to preventable diseases, we must get them vaccinated.
