Serious questions raised by a vaccine shortage are being addressed by national governments and other health agencies.

The United States is reportedly rushing more than 400,000 doses of the meningitis B vaccine from India to the U.S. once a shortage is resolved. It is unclear whether this would be enough, or when exactly the shipments will be arriving, but the Department of Health and Human Services told The Wall Street Journal that the medicine has already been deployed to Tennessee and Georgia and a number of other states are also importing the medicine.

Who should get vaccinated? Why the shortage?

Inspections are under way at 96 U.S. labs, and researchers at a U.S. Department of Agriculture lab have been taken off work pending tests on samples they may have handled previously.

The inquiry has started because the high-contamination rate discovered at the CDC lab resulted in the recall of 1.6 million eggs. For many years the CDC has studied viruses that have been shipped from different labs and released them into the food chain, and tests are being done to see whether any of those samples have infected chickens, turkeys or other livestock animals.

Why the Eagle Scout controversy?

Michael Bloomberg’s position that the Boy Scouts of America should allow gay members is sparking a heated national debate that touches on such deeply personal matters as religion, sexual orientation and sexuality.
