Three Stories About the Need to Vaccinate

March 31, 2020 by Will Sowards Leave a Comment

several vaccine vials

Measles is, without a doubt, a fairly scary virus. In 2014, there were just under 200,000 measles cases confirmed by the World Health Organization across the world. That number is about 92 percent less than where it was in 1980, when 2.6 million cases were reported. This decline is attributed to one thing: measles vaccination.

The WHO, Centers for Disease Control, and medical organizations all around the world plead with parents asking them to get their children vaccinated to avoid measles and other deadly diseases. However, despite numerous studies showing that vaccines are safe, some individuals claim that vaccination is unsafe and can cause serious side effects. These voices are generally loud, and involve many Hollywood stars who receive significant international attention despite espousing often ill-informed beliefs.

But, there are some famous and well known individuals who have touching and important stories about the safety and importance of vaccines, beliefs backed by literally hundreds of studies proving that vaccines not only work, but have few to no harmful side effects and will save lives.

How Cows Helped Jump Start Vaccines

March 26, 2020 by Will Sowards Leave a Comment

Edward Jenner's research saved millions of lives and paved the way for future vaccines.

Today, few question the legitimacy of a vaccination. Even fewer people consider a time when vaccinations were completely nonexistent. It is bizarre to think we owe our thanks to a cow, a dairymaid, an eight-year old boy, and the doctor who made a connection between them all.

People refer to Dr. Edward Jenner as “the father of immunology”. Immunization was not new, but Jenner was the first to study and document vaccination use. His curious experiment has saved an innumerable amount of human lives.

Smallpox was the greatest killer of Jenner’s time. In its most common form, the virus killed about 30% of those who caught it. It was the most feared disease that reached every part of society – even royalty suffered from it.

Smallpox is a virus that causes flu-like symptoms later accompanied by raised pink spots that grow over time. The spots cover the entire body. If the victim recovers, the blisters will shrivel up and fall off. They often leave behind sunken scars.

A similar but far less deadly disease than smallpox, is cowpox. This virus, which originates from cows, can transfer from animals to humans. It wasn’t uncommon for dairymaids to experience the mild infection. They would feel run down for a couple of days and develop some pocks, usually on their hands. Other than this, the sickness was harmless and did not cause any concern.

At the young age of thirteen, Jenner was an apprentice to a country surgeon. During his apprenticeship he overheard a dairymaid working nearby say, “I shall never have smallpox for I have had cowpox. I shall never have an ugly pockmarked face.”

Jenner took note of dairymaids’ natural immunity to smallpox. Many believed that those who had contracted cowpox were immune to smallpox.

Years later in 1796, a dairymaid consulted Jenner about a rash on her hand. Seeing the mildness of the infection, he diagnosed her with cowpox. She later verified to him that one of the cows she was working with recently had cowpox. Jenner saw this as his golden opportunity to prove the disease’s protection from smallpox.

To test his hypothesis, Jenner needed someone who never contracted cowpox or smallpox before. His gardener’s eight-year old son served as a perfect candidate. Jenner collected drops of fluid from the sores on the dairymaid’s hands and injected a small amount into the healthy boy’s arm. The boy became mildly ill with the cowpox infection, but recovered about a week later.

Two months later, Jenner injected some fluid from a smallpox sore into the young boy. As Jenner expected, the boy never became sick. To confirm his findings, Jenner continued to test the boy’s immunity. Hi various experiments all proved his hypothesis correct.

Jenner soon coined the word “vaccination”, of which the root word is derived from the Latin word “vacca”, meaning cow. Jenner published his research and discoveries, excited to share his success with the world.

Despite the success of Jenner’s techniques and findings, he faced opposition from others in the medical field. One criticizism was that cowpox wasn’t common. It was usually found in rural areas with farms having cows and dairymaids. This meant many doctors would have to get the vaccine from Jenner.

Edward Jenner continued to attempt to win approval as well as spread his new vaccine to the world. He came up with new, easy ways to have the cowpox matter widely transported. He was successful in his commitment to his scientific discovery.

Jenner’s work helped eradicate smallpox. Samples of the virus only exists in two labs permitted and trusted to secure it.

Jenner himself laid the foundation of vaccination as we know it today.

What Does a Pandemic Mean?

March 11, 2020 by Will Sowards Leave a Comment

Travelers and locals alike take measures to prevent viruses during a pandemic.

On March 11, the World Health Organization announced that coronavirus (COVID-19) is officially a pandemic.

For months, countries around the world had already been taking action against the virus. Increased cases led to mass quarantines and more testing.

But, the decision from the WHO is rare, even for a disease that’s spread worldwide. The world’s last official pandemic was in 2009, caused by the H1N1 swine flu.

With the entire globe now working to slow the COVID-19 pandemic, what does that term mean?
