Ever Wondered How Our Ancestors Survived Without Costly Vaccinations?

Published on 14 June, 2017 at 8:03 pm By

We have survived nature’s wrath and world wars, but one question still stands: How did we survive without modern-day medication and vaccination?

Basic vaccination and medical facilities are considered to be a must for favorable living conditions. However, there have been times when we were not injected with chemicals to fight against diseases and ailments. Those were the times humans wandered in a pack to hunt and gather food.

The secret of survival is the lack of contact with other tribes or communities. The prehistoric human was a hunter.

They kept moving from one place to another in search of food. Therefore, the concept of socializing with human groups did not exist. So, when there was less mingling with another body, the chance of contracting diseases decreased.



 

We know how viruses spread through different modes and cover a long distance in their pursuit of destruction. The cars, trains, flights, etc. keep shuffling people from one land to other. A human body acts as a carrier for these diseases that spread globally with a bigger magnitude.

We need to come in contact to be the carrier and there wasn’t any scope of it for humans in the past until the arrival of agriculture. As soon as humans started to domesticate, they began living in close proximity with livestock and the harvest.

There were other reasons which contributed to the subsequent fall of human immunity and emergence of vaccination. Another popular theory suggests that humans survived because the females were procreating as soon as they hit puberty. Though the child mortality rate was high, the rate of reproduction was higher than that of modern times.
