On March 26, 1953, Dr. Jonas Salk went on CBS radio to announce his vaccine for poliomyelitis. He had worked for three years to develop the polio vaccine, attacking a disease that killed 3000 Americans in 1952 alone, along with 58,000 newly reported cases. Polio was a scourge, and had been infecting humans around the world for millennia. Salk's vaccine was the first practical way to fight it, and it worked—polio was officially eliminated in the U.S. in 1979.

Salk's method was to kill various strains of the polio virus, then inject them into a patient. The patient's own immune system would then develop antibodies to the dead virus, preventing future infection by live viruses. Salk's first test subjects were patients who had already had polio ... and then himself and his family. His research was funded by grants, which prompted him to give away the vaccine after it was fully tested.

Clinical trials of Salk's vaccine began in 1954. By 1955 the trials proved it was both safe and effective, and mass vaccinations of American schoolchildren followed. The result was an immediate reduction in new cases. Salk became a celebrity because his vaccine saved so many lives so quickly.

Salk's vaccine required a shot. In 1962, Dr. Albert Sabin unveiled an oral vaccine using attenuated (weakened but not killed) polio virus. Sabin's vaccine was hard to test in America in the late 1950s, because so many people had been inoculated using the Salk vaccine. (Sabin did much of his testing in the Soviet Union.) Oral polio vaccine, whether with attenuated or dead virus, is still the preferred method of vaccination today. Polio isn't entirely eradicated around the world, though we're very close.

Here's a vintage newsreel from the mid 1950s telling the story:

Crocs have long been a favorite among healthcare workers who spend hours on their feet each day—and now, they can get a pair for free.

This week, the company announced that it will give away more than 100,000 pairs of shoes to medical professionals fighting the new coronavirus in the U.S. ClickOrlando reports that workers can submit their requests for Crocs Classic Clogs or Crocs at Work via an online form on the Crocs website, which will open each weekday at 12 p.m. EST and continue accepting orders until it fulfills its daily allotment.

According to a press release, that allotment is a whopping 10,000 pairs of shoes per day. The as-yet-unspecified end date for the program—called “A Free Pair for Healthcare”—depends on inventory levels and the number of requests the company receives. In addition to shipping shoes to individuals, Crocs is also planning to donate up to 100,000 more pairs directly to healthcare organizations. So far, they’ll send shoes to the Dayton Area Hospital Association in Ohio, St. Anthony North Health Campus in Denver, Colorado, the Atlantic Health System in New Jersey, and more.

“These workers have our deepest respect, and we are humbled to be able to answer their call and provide whatever we can to help during this unprecedented time,” Crocs president and CEO Andrew Rees said in the release. “Share the word to all those in healthcare and please be mindful to allow those who need these most to place their requests. This is the least we can do for those working incredibly hard to defeat this virus.”

Healthcare professionals can request their free Crocs here.

Can't Find a Medical Thermometer? Use a Digital Meat Thermometer to Take Your Temperature

Toilet paper and masks aren't the only items disappearing from stores during the novel coronavirus crisis. A fever is one of the most common symptoms of COVID-19, and people have been stocking up on thermometers as a precaution. If you find yourself feeling sick and can't find a medical thermometer to take your temperature, using a meat thermometer works in a pinch, according to Lifehacker.

Like oral thermometers, instant-read digital meat thermometers use sensors and a bit of computing power to calculate the temperature of whatever you stick them into. That means they work just as well for detecting fevers as they do for telling you when your steak is overcooked.

When using a kitchen tool for medical purposes, the most important thing to remember is sanitation. Disinfect your meat thermometer by swabbing the probe with rubbing alcohol. Once it's clean, you can hold it under your tongue like you would a regular thermometer. The major differences are that a food thermometer won't beep when it's done calculating, and the sharp tip is meant for penetrating meat, so you have to be careful when sticking it into your mouth. After your temperature has been measured, don't forget to sanitize the device again with alcohol before putting it away.

If you suspect you may have a fever, educate yourself on the number to look for on the thermometer. Standard human body temperature is commonly described as 98.6°F, but recent research has shown that the average may be slightly lower today.
