Key Technician in the Development of the Measles Vaccine
Ann Holloway had a bird's eye view of measles research. A longtime associate of John Enders, he eventually came to see Holloway as his "most able technician and associate." Prior to her work on the measles vaccine, Holloway helped Enders develop the polio vaccine, for which Enders won the Nobel Prize. Holloway teamed with Dr. Arne Svedmyr to develop a diagnostic tool, known as a compliment fixation test, to assess the activity of polio antibodies. As other team members went their separate ways, Holloway stayed on and joined Enders in pursuing the development of a measles vaccine. After they successfully isolated the measles virus they began the arduous task of passaging the virus through human cells. The process was painstakingly slow but, in the end, her persistence paid off. Holloway's contributions were critical to the successful development of the live-virus vaccine.This accomplishment was more satisfying, and more socially significant, than his previous Nobel Prize winning work on the poliomyelitis virus according to John Enders.
Measles is caused by a virus and is one of the most contagious diseases known. The virus normally grows in the cells lining the back of the throat and those lining the lungs. The first sign of infection is a high fever lasting one to seven days. During this initial stage the patient may develop multiple symptoms, including a runny nose, cough, red and watery eyes, and small white spots inside the cheeks. A rash develops after several days, typically beginning on the face and upper neck, and then spreading to the hands and feet. Poorly nourished children are at an increased risk of contracting a severe case of measles, especially those who have a vitamin A deficiency or whose immune system is compromised. Childhood deaths are usually caused by the complications associated with measles. The most serious complications include blindness, an infection of the brain and spinal cord (encephalitis), severe diarrhea, ear infections and severe respiratory infections, such as pneumonia, which is the most common cause of death associated with measles. Due to widespread use of the measles vaccine, U.S. cases now range from the 10s to the low 1,000s. Worldwide measles deaths have also plummeted. In 2000 it was estimated that 6,000,000 people a year died from measles, mostly children. Now in 2021 that number is down to 120,000, all due to the measles vaccine. About 85% of all the children in the world now receive a measles vaccination.

Vaccines are Ubiquitous & Omnipresent Throughout Our Lives
It is bizarre that vaccines are controversial, when virtually everyone has had vaccines.
The average person born today may get 70+ vaccines in their lifetime.
There are 31 childhood vaccines (counting booster shots). Over 90% of people have received some of these vaccines.
Did you know that all beef, poultry, and pork you eat comes from vaccinated animals?
And that all horses, dogs, cats, and zoo animals are vaccinated?
Who wants to live in a world where you can’t pet your friends’ dog because it may not have been vaccinated, and may have rabies?
