The most striking feature of the H1N1 flu vaccine manufacturing process is the 1,200,000,000 chicken eggs required to make the 3 billion doses of vaccine that may be required worldwide.
For the shot vaccine, the virus is sterilized so that it won’t make anyone sick. This is the magic part of the vaccine: it’s got the pandemic virus antigens that make your body produce the antibodies to fight the virus but the virus is inactive so it won’t make you ill.
