Textbook Question
Chapter 18, Problem 6AWK
The first cancer that can be nearly completely prevented by a vaccine is cervical cancer. How does the vaccine work? If a vaccine can be developed against cervical cancer, why hasn't someone developed a vaccine against the number one cancer killer–lung cancer?

1) What factor(s) most likely account for the increase in the diagnosis of autism spectrum disorders (ASDs) over the past two decades? 2) What does the research say about the purported link between vaccines and ASDs? 3) Would you or would you not choose to have your child receive routine childhood vaccinations?
Which example would benefit most from the use of pluripotent stem cells made from the patient's own cells?
A) An autoimmune disease, inappropriate targeting of the patient's immune system, destroyed a patient's thyroid gland
B) A neurodegenerative disease, abnormal cell death of brain cells, destroyed a specific region of the patient's brain
C) A patient suffered severe burns over much of their legs and feet
D) A person with a congenital disease has been blind from birth.
In 2007, then–Texas governor Rick Perry became the first governor in the United States to mandate by executive order the vaccination of all Texas girls aged 11–12 for HPV, arguing that the vaccine prevented cancer. Some conservatives criticized Perry, arguing that the vaccine would encourage sexual promiscuity among children and young adults. The Texas legislature overturned the executive order, and Perry later reversed himself, saying the order was a mistake. Do you think states should require boys and girls to be vaccinated for HPV? Discuss reasons for and against such a requirement.

- Polio (poliomyelitis) is a serious disease that either kills or paralyzes a large number of people (especially children) before the development of the vaccine. The first vaccine against polio was developed by the American doctor Dr. Salk in the 1950s. The effectiveness of the vaccine was studied using the following experimental setup: 400,000 elementary school children from grades 1, 2, and 3 participated in the experiment. 200,000 children were vaccinated and 200,000 children were not vaccinated. For each child in the experiment, a coin was flipped. If the result of the flip was heads, the child was placed in the treatment group and received the vaccine injection. If the result was tails, the child was placed in the control group and received a placebo injection (dummy vaccine). The health status of the children was then monitored over a certain period. The children participating in the experiment, their parents, the doctors who administered the injections, and the doctors who…arrow_forwardLaura Brennan, a human papillomavirus (HPV) vaccine advocate and cervical cancer casualty, was diagnosed with HPV-16-associated cervical cancer at age 24. In 2018, U.S. health officials extended the allowable age for the HPV vaccine to 45. Determine which patients will have the greatest chance of protection from the Gardasil vaccine, which prevents infections of nine strains of HPV including HPV-16 and HPV-18 and five additional types of cancer-causing HPV as well as strains HPV-6 and HPV-11 that cause genital warts. Recall that vaccines train the body's immune system to recognize a particular infection (see figure). Disease Vaccine Vaccine Antibodies organisms Antibodies A vaccine with an inactive form or harm- less amount of a virus The vaccine stimulates When the individual is the immune system to produce antibodies (in green) that recognize exposed to the virus after vaccination, the new antibodies are primed to attack the invader.

- Which of the following statement(s) about DNA vaccines is(are) NOT true? Check all that apply. A.) DNA vaccines are an example of "ex vivo" vaccination; cells are removed from the body, transfected with DNA expressing the antigen(s) of interest, and then the cells are returned to the body. B.) DNA vaccines can be used to immunize with multiple different antigens. C.) DNA vaccines only stimulate B cell responses. D.) DNA vaccines only stimulate T cell responses.

As a precaution, you vaccinate her against tetanus. In response to the vaccine, how does her body produce antibodies against C. tetani and prevent future illness due to tetanus? A)B cells that produce an appropriate antibody undergo genomic rearrangement in order to produce other cells that secrete the same antibody. B)Every cell in her immune system produces antibodies against C. tetani. C)B cells with an appropriate antibody are stimulated to divide, producing plasma cells that make antibodies to C. tetani, and memory cells that "remember" C. tetani. D)Every B cell in her body produces antibodies against C. tetani.arrow_forward
- Why is counselling required before an HIV test can be done on a patient? We don't counsel patients when we look for a tumour marker to diagnose cancer, which is often more serious for a patient.arrow_forwardIt used to be that our only method of creating vaccines was to use dead or weakened pathogens. That is no longer the case - what are some newer options that are available to researchers?arrow_forwardStudies have shown that there are significant differences in cancer rates among different ethnic groups. For example, the Japanese have very high rates of colon cancer but very low rates of breast cancer. It has also been demonstrated that when members of low-risk ethnic groups move to high-risk areas, their cancer risks rise to those of the high-risk area. For example, Japanese who live in the United States, where the risk of breast cancer is high, have higher rates of breast cancer than do Japanese who live in Japan. What are some of the possible explanations for this phenomenon? What factors may explain why the Japanese have higher rates of colon cancer than do other ethnic groups?arrow_forward
