Measles

Why do you need to know the TB status before administering Measles vax?

Found this on the CDC website: http://www.cdc.gov/mmwr/preview/mmwrhtml/00001090.htm

Tuberculosis: Tuberculosis may be exacerbated by natural measles infection. There is no evidence, however, that the live measles virus vaccine has such an effect. Therefore, tuberculin skin testing is not a prerequisite for measles vaccination. The value of protection against natural measles far outweighs the theoretical hazard of possibly exacerbating unsuspected tuberculosis. If there is a need for tuberculin skin testing, it can be done on the day of vaccination and read 48 to 72 hours later. If a recent vaccinee proves to have evidence of tuberculous infection, prompt investigation and, if indicated, preventive treatment or treatment for tuberculous disease should be initiated. It is prudent to wait 4-6 weeks after measles immunization before administering a tuberculin skin test since measles vaccination may temporarily suppress tuberculin reactivity.

Thank you very much. I wasn't able to find it by googling. You've saved me!!!
