That could explain the lack of protection among the vaccinees - the shot may have been protecting against the wrong flu proteins. Targeting the correct strain is a always a bit of a guessing game...
...second-line anti-TB drugs available - and there is no third line of pharmaceutical defense. While some promising candidates are being tested, even if they prove effective, they will not be available for at least five more years. There is also no easy way to detect drug-resistant strains of TB; current sputum-based screens can take anywhere from two weeks to two months, during which time doctors protectively place infected patients on first-line drugs too weak to battle the aggressive strain effectively rather than risk the overuse of last-resort medications that would only feed drug resistance...
