That same drug company that produces lovastatin, Merck, yesterday recalled a common children's vaccine. The HIB vaccine guards against meningitis, pneumonia, and other serious infections; it's routinely administered to babies beginning at around two months old. The recall covers about 1.2 million doses of the vaccine distributed since April.
It was issued after concerns were raised over risks of contamination at a Pennsylvania factory. So far there haven't been any reports of contaminated vaccines, and officials say they do not know of a health threat. But there are concerns of a shortage of HIB vaccine. A Merck official told the Associated Press that the company will not be able to supply any vaccine for at least nine months.
