Episode 3-Too Many, Too Soon

Let's begin with intuition.

Imagine someone handed you a backpack.

It weighs 10 pounds.

No problem.

Now imagine someone adds another 10 pounds, and another.

Eventually, the backpack becomes too heavy.

That's how we think about almost everything.

More weight equals more strain.

More homework means more stress.

More medications usually mean more side effects.

So it's natural to assume more vaccines must place more stress on the immune system.

But here's the interesting part.

The immune system doesn't work like a backpack.

It works much more like a massively parallel processing network.

It's built to respond to thousands of different challenges simultaneously, every single day.

So let's talk a little more about how the immune system actually works.

The moment a baby is born, they're no longer living in the protected environment of the womb.

They enter a world filled with bacteria, viruses, fungi, pollen, dust, foods, and countless other foreign substances.

The first breath exposes the lungs to microbes.

The first feeding introduces proteins and bacteria.

Skin touches parents, hands touch blankets, babies put fists into their mouths.

Later, they'll chew on everything, toys, furniture, shoes, and just about anything else they can reach.

From the immune system's perspective, this is an avalanche of new information, and that's exactly what it was designed for.

Our immune system isn't built to respond to one thing at a time.

It's constantly monitoring thousands of potential threats all at one time.
