Often called the world’s oldest profession, prostitution has been common since ancient times (Ringdal, 2004). In ancient Mesopotamia, priests had sex with prostitutes. Ancient Greece featured legal (houses of prostitution) that serviced political leaders and common men alike. Prostitution was also common in ancient Rome, and in the Old Testament it was “accepted as a more or less necessary fact of life and it was more or less expected that many men would turn to prostitutes” (Bullough & Bullough, 1977, pp. 137–138). During the Middle Ages and through the nineteenth century, prostitution was tolerated as a necessary evil, as legal brothels operated in much of Europe and were an important source of tax revenue. As the dangers of venereal disease became known, some cities shut down their brothels, but other cities required regular medical exams of their brothels’ prostitutes.

Subunit or split particle vaccines contain fragments of germs, not the whole thing. Some diseases are not caused by the germ itself, but by a toxin that the germ produces. Toxoid vaccines are made to prevent that kind of disease, and so contain an inactivated toxin (known as a toxoid), but not the germ itself.

Tuberculosis is spread from person to person by the airborne route. In childhood, the lung is the first site of infection and most infections resolve with local scarring (the primary complex). In about 5% the infection is not controlled and it spreads from the primary focus throughout the body (miliary spread). This may resolve spontaneously or develop into other localized infections (e.g. meningitis, osteomyelitis). Disease may emerge if immunity wanes or in later life (10% lifetime risk). Immunity depends on effective T-cell function so if compromised, individuals are more likely to develop symptomatic disease.
