“Hand sanitizers contain chemicals that inactivate many viruses and are extremely convenient to use,” says infectious disease expert Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins ...
The FDA fired off a warning letter to Purell's parent company, Gojo Industries, over their marketing claims that the hand sanitizer could kill viruses such as the flu and Ebola.
Purell is an American brand of hand sanitizer invented in 1988, and introduced to the consumer market in 1997, by GOJO Industries.

Vaccines are another method of virotherapy that use attenuated or inactivated viruses to develop immunity to disease. An attenuated virus is a weakened virus that incites a natural immune response in the host that is often undetectable. The host also develops potentially life-long immunity due to the attenuated virus's similarity to the actual ...
The potential of viruses as anti-cancer agents was first realised in the early twentieth century, although coordinated research efforts did not begin until the 1960s. [7] A number of viruses including adenovirus, reovirus, measles, herpes simplex, Newcastle disease virus, and vaccinia have been clinically tested as oncolytic agents. [8]
Adenoviruses can lead to tumors in rodent models but do not cause cancer in humans; however, they have been exploited as delivery vehicles in gene therapy for diseases such as cystic fibrosis and cancer. [15] Simian virus 40 (SV40), a polyomavirus, can cause tumors in rodent models but is not oncogenic in humans. [16]
