The earliest smallpox vaccines were infected tissue rubbed into the skin of a healthy person. The recipient of such a vaccine usually developed a mild case of smallpox, recovered, and was immune thereafter. What is the most likely reason this vaccine did not kill more people?
- a. Skin is the wrong portal of entry for smallpox.
- b. The vaccine consisted of a mild form of the virus.
- c. Smallpox is normally transmitted by skin-to-skin contact.
- d. Smallpox is a virus.
- e. The virus mutated.

Why is smallpox so dangerous?

a. What does each method have in common with the others?
b. What is one difference between the three methods?

- Which of the following is a commonality between coxsackievirus A16 infection and a varicella zoster infection?Choose one: A. Both infections are caused by viruses in the herpes family. B. Each disease is usually mild and self-limiting in children but is more severe in adults. C. Both viruses can cause a spotted rash to appear on the palms of the hands and soles of the feet. D. There is a vaccine available for both viruses.arrow_forwardIdentify the statement that does not provide accurate evidence as to why HIV is so lethal. a. During the course of infection, HIV increases immune activation by altering intestinal physiology to let more microbes into the blood supply. b. Immune evasion increases in many infections due to HIV virions evolving new and unrecognizable epitopes (antigens). c. In many individuals the virus population evolves to use different receptors to gain access to a greater diversity of host immune cells. d. HIV causes enhanced replication and proliferation of T cells, which allows the immune system to work better at defending against pathogens.arrow_forwardIndicate whether each of the following statements is true (T) or false (F). a. An unsubstantiated association between the MMR vaccine and autism has led some parents to choose not to vaccinate their children. b. The hepatitis B vaccine is associated with cancer of the liver. c. Acellular vaccines have fewer side-effects than cellular vaccines. d. Recombinant DNA technology can be used to reduce the virulence of pathogenic viruses. e. The Rotarix vaccine is a subunit vaccine composed of purified VP4 and VP7 glycoproteins of the human rotavirus. f.
