This is an old technique used to isolate attenuated organisms for use in vaccine development.
Attenuation refers to rendering an organism (bacteria or virus) less virulent or pathogenic (less dangerous to humans). This is accomplished by infecting one animal, taking the infection from that animal to infect the next, and so on in a controlled manner. After several passages, the bacteria or virus is adapted to live in the animal host and not in humans and so can sometimes work as a vaccine.
An example of this is the smallpox vaccine which was attenuated in cattle.

What is fluid attenuation?
It means regulating the passage of fluids.
Does attenuation happen when EM wave travels in space?
There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.
When did the pilgrims exchange for passage to America?
Animal skin
What is the benefit of an attenuation pond?
An attenuation pond is a pond which is designed to slow the passage of water from surface run-off to the ground/drainage system e.g. stormwater sewers. It does this by storing the run-off during times of peak flow i.e. heavy rainfall, and slowly releasing it at a controlled rate after the peak flow has passed.
Where can you find information about attenuation?
Attenuation means the reduction of signal strength during transmission. If one is looking for information about attenuation, it can be found on the Wikipedia website.
What is the opposite of attenuation?
The opposite of attenuation is amplification. Amplification involves increasing the strength or intensity of a signal, sound, or electrical current, while attenuation involves decreasing it.
Non-desructive attenuation for attenuation measurement in optical fiber?
Because race car.
What is a good value for dB attenuation?
A good value for dB attenuation depends on the specific application. In general, higher dB attenuation values indicate better noise reduction or signal loss. For example, a dB attenuation value of 20-30 dB is commonly seen in noise-canceling headphones, while 40-60 dB attenuation is typical for industrial ear protection.
What is Low attenuation lesion in the left kidney?

How does network cable length affect attenuation?
longer cable lengths have greater signal attenuation

Where in the bible did God turn king into animal?
In Daniel 4 Nebuchadnezzer is made like an animal, but there is no passage that says anyone is turned into an animal.
