Which of the following is a reason the vaccine for SARS-CoV-2 should not be a live attenuated vaccine? a. Live attenuated virus vaccines will most likely cause lung damage. b. Live attenuated virus vaccines often need extensive safety testing. Some live viruses can be transmitted to a person who isn't immunized. This is a concern for people who have weakened immune systems. c. The live attenuated vaccine will not last and needs too many booster shots to be effective. d. The live attenuated vaccine will confer illness to a high percentage of patients, prolonging the epidemic.

Live attenuated virus vaccines might cause lung damage, but this is not a primary concern for SARS-CoV-2 specifically. b. Live attenuated virus vaccines often need extensive safety testing, and some live viruses can be transmitted to a person who isn't immunized. Show more…

Which of the following statements best describes vaccines? a. Vaccines kill viruses. b. Vaccines stimulate an immune response against future infections. c. Vaccines inhibit the virus by blocking the action of key viral proteins. d. Vaccines control and reduce symptoms.
Select the answers to the following questions: One problem with vaccines that contain killed pathogens is that. Attenuated vaccines typically cause a stronger immune response because. A toxoid, which contains denatured toxin from a pathogen, would best be described as an example of. they cannot be given to immunocompromised people. they are given to people with a weakened immune system. Subunit vaccine. Recombinant vaccine. the pathogens used in these vaccines are extremely virulent. they may not stimulate a strong response. Killed vaccine. they are given to people who have a very strong immune system. the pathogen can still multiply in the host. large numbers of pathogens are used in them. Attenuated vaccine. the pathogen may reactivate and cause disease. they may stimulate an excessive immune response. Inactivated vaccine. they can only be given to immunocompromised people.

6. Many infections can be prevented by vaccination. However, people who are immunocompromised cannot safely receive "live-attenuated" vaccines, but they do benefit from "component vaccines" and from "herd immunity." a. How are live-attenuated vaccines different from component vaccines? (4 points) b. In what circumstances are live-attenuated superior to component vaccines? Inferior? (4 points) c. Why are component vaccines safe for immunocompromised people, but live-attenuated vaccines not? (4 points) d. What is herd immunity? How does it protect immunocompromised people? (4 points)
