An HIV-positive client questions the nurse about a vaccine for HIV. Which response by the nurse is most accurate?
1. "Scientists are far from developing a vaccine to prevent HIV."
2. "The HIV vaccines developed can prevent fatal consequences of the virus."
3. "Scientists currently have many HIV vaccines in clinical trials."
4. "Scientists are close to discovering a vaccine for HIV."
Correct Answer: 1
Rationale 1: Despite much research, scientists are far from developing a vaccine to prevent HIV.
Rationale 2: The HIV vaccines that have been researched cannot prevent fatal consequences of the virus.
Rationale 3: There are not many HIV vaccines in clinical trial.
Rationale 4: Despite much research, scientists are far from developing a vaccine to prevent AIDS.
Global Rationale: After decades of research, the FDA has not approved a single vaccine. Only a few HIV vaccines are currently in clinical trials, and none is expected to cause a major impact on the HIV epidemic. At best, the HIV vaccines produced thus far only boost the immune response; they are unable to prevent the infection.
