I believe these types of vaccines are not as important (necessary) as airborne ones.

Not true with small pox, whooping cough and many of the other commonly vaccinated diseases.

Smallpox

Transmission occurs through inhalation of airborne variola virus, usually droplets expressed from the oral, nasal, or pharyngeal mucosa of an infected person. It is transmitted from one person to another primarily through prolonged face-to-face contact with an infected person, usually within a distance of 6 feet (1.8 m), but can also be spread through direct contact with infected bodily fluids or contaminated objects (fomites) such as bedding or clothing.
