birds in the industry that's a lot of birds. Andrew Reed, an evolutionary biologist at Penn State University.

He says the virus was easy to catch.

So the dander of chickens is full of the virus.

If you shake a chicken, the virus drops out. Then in 1970 a new vaccine put an end to most of the deaths,

but the poultry vaccine, unlike most, was a so-called leaky or imperfect vaccine.

The vaccine is life saving, that's the point of the vaccine,

but it allows the infection to persist and transmit from a host.

Meaning you could still shake a vaccinated chicken

and make it rain viruses.

Now Reed and his colleagues have shown that these leaky vaccines may actually give some
