Sabin and the vaccine that changed the world

Dr. Albert Sabin is famous for his development of the live oral polio vaccine and for the attempt to eradicate polio by vaccinating an entire population all at once. His commitment to the eradication of polio saved many children from death and paralysis and still does today.

He is an inspiration to us all! Please read this interesting story about Sabin’s accomplishments. I think you’ll enjoy it!

What does stress do to the immune system?

Do you find yourself with a cold or major health issue after a stressful event? I most certainly do.

I’m constantly full of anxiety trying to do everything, and it’s not just all of the lists, and kids, and home maintenance, and work, and writing these articles (which I love doing); it’s a personality trait, and it’s quite common.

All of these little things in our lives add up and cause us STRESS.

So, what’s stress?

We can define it as a state of mental tension and worry caused by problems in our lives.

When you feel stressed your body releases chemicals in response to stress hormones circulating through the body. Sometimes these hormones can be useful, however often they are very hard on the body and can leave you susceptible to infection.

When is stress useful?

You’ve most likely heard of the ‘fight or flight’ response–a survival alarm system dated way back to the beginning of human life. This response occurs in the face of real danger and causes the hypothalamus to stimulate the adrenal glands to start pumping adrenaline. This gives your body the energy to either fight or flee from a dangerous situation. We still use this response today in the face of say, encountering a bear on a hike or a mugger on the street.

Stress chemicals may also be useful before a big event when you may need a burst of energy or alertness to improve performance. This might be beneficial during a job interview or before a big test.

But, chronic stress is often harmful.  Continue reading

Guest Author – How do chickenpox and shingles differ from each other? – Maria Fualo

For starters, both shingles (herpes zoster) and chickenpox (varicella) is a result of the same virus called the varicella-zoster virus, but they occur at different ages. Chickenpox can occur at any age, and shingles can occur any time after the person has had chickenpox. The two diseases bring a lot of discomforts to patients. In most cases, they irritate the skin and cause a blistering rash that scabs and may scar.

Whey They Occur and Physical Characteristics

The chickenpox is common in children below five years, while shingles infects typically people over 50 years. Shingles, however, can cause infection in anyone at any age if the chickenpox virus has already infected their body, mostly the elderly. Many cases of infection come from people above 50 years old.

Chickenpox and shingles do tend to differ in look. Chickenpox causes itchy blisters to form all over the body, sometimes internally. Shingles is very painful and often starts with localized numbness/tingling and often but not all the time, a rash. The shingles rash typically displays on one side of the body due to the fact that the follow along nerve pathways.

The blistering rash does not move all over the body like chickenpox does, but stays localized. The most common areas for the appearance of the rash would be the torso and face. It’s quite uncommon for the rash to spread elsewhere. Continue reading

Professor of Cell Research & Immunology at Tel Aviv University, Jonathan M. Gershoni, wants to welcome all of you to join his new FREE online class “Viruses & How to Beat Them: Cells, Immunity, Vaccines“.

This is a class welcome to anyone interested in basic cell biology, virology and immunology. There is no need for a well-developed understanding of science. The free online class is geared to non-science/biology majors, parents, and adults at or above the high school level.

What will you learn?

  • The makeup of cell structures (organelles) and their functions
  • What happens to our body when it is infected by viruses
  • How our immune system operates to protect us
  • The pros and cons of vaccination

The course is intended to help you make informed decisions about vaccines and better appreciate how our bodies cope with viral infections. But it’s not all about throwing information at you. The professors and speakers in the course keep it light and entertaining.  Continue reading
