Imagine the cover story you would float if you had to buy 200 million eggs for an emergency vaccine.
You wouldn’t want to alarm the population, so you’d have to make some excuse for why those eggs weren’t being sold onto the market, right?!
LOL!
Eggs contaminated with salmonella would never be used for a vaccine.
Eggs used for vaccine come from dedicated flocks, which are maintained in a pathogen free environment. People taking care of chickens that produce vaccine eggs must wear protective clothing to prevent passing disease to the chickens.
