Why Humans Only Need To Vaccinate A Few Bats

SciShow · 54,288 views · Added 1 month ago

AI Summary

In this video, you will explore the science of rabies transmission and modern efforts to control it. The lesson explains why the virus is so deadly, how it spreads through vampire bat colonies, and why traditional "extermination" methods are often ineffective or harmful. Most importantly, you will learn about an innovative, non-lethal solution: using a specialized, edible gel—similar to the thickeners found in hot cocoa—to distribute vaccines through the bats' natural social grooming behaviors. This video is an excellent resource for expanding your scientific vocabulary and understanding how researchers apply creative solutions to complex public health challenges.

You’ll probably never get rabies,

00:04

but that doesn’t make it any less terrifying.

00:07

The disease is virtually always  fatal once symptoms emerge.

00:10

And while we have some post-exposure treatments,

00:13

they rely on getting to the doctor in time.

00:15

So a much better solution would be  to prevent rabies in the first place.

00:18

And to do that, it’s animals that we need

00:20

to figure out a better solution for.

00:22

Because they’re the ones  who often transmit it to us.

00:25

Which is extra complicated when we want

00:27

to curb the spread of rabies due to vampire bats.

00:30

Since their whole deal is biting other animals,

00:33

stopping them from spreading  rabies along the way isn’t easy.

00:36

But new research shows the solution to vampire

00:39

bat rabies might be an  ingredient in your hot cocoa.

[♪INTRO]

00:45

Rabies is an RNA rhabdovirus  found in the Lyssavirus genus.

00:50

It almost always passes to  humans via an animal bite,

00:53

and it can take days to months  for symptoms to show up.

00:56

These include headaches, vomiting, confusion,

00:59

fear of water, and  hallucinations, all of which are

01:02

thanks to the virus infiltrating  the central nervous system.

01:05

Once symptoms do appear, the  patient dies within 2 or 3 days

01:08

of going to the hospital,  basically 100% of the time.

01:12

A last ditch effort is the Milwaukee Protocol,

01:15

where doctors put the patient  into a medically induced coma,

01:18

pump them with antivirals, and hope for the best.

01:20

But only about a couple dozen  people have survived, and

01:23

they often have major neurological  deficits after all’s said and done.

01:27

And it’s not just human lives on the line either.

01:29

Cattle are frequent rabies victims,

01:31

with economic impacts in the  tens of millions of dollars.

01:35

So preventing their infections  could save their lives,

01:38

and also all the beef, dairy,  and money that comes with them.
