While Bush is vetoing...

Merck, one of the largest pharmaceutical companies in the world, has pulled almost a million doses of a children's vaccine off the market, but still claims there is no threat to the general public. We'll see how this turns out.

From MSNBC:

Day vaccine maker Merck announced they are issuing a precautionary recall of close to a million doses of their Hib vaccine after a Pennsylvania factory developed a sterilization problem...

Merck officials say the vaccine itself does not appear to be contaminated but there will be a shortage while they work on their sterilization problem. CDC officials say this is not a health threat and there have not been any adverse events reported.

However, this is not a "no risk" situation.
