Question

1. which claim about the rabies vaccine is most supported by the graph?

a. rabies vaccine is dangerous
b. rabies vaccine can reduce infections in humans and dogs
c. rabies vaccine can increase infections in dogs
d. rabies vaccine has no effect on humans

Explanation:

To determine the correct claim, we analyze each option:

• Option a: There's no data in the graph (implied by the context of the question) to support that the rabies vaccine is dangerous.
• Option b: Vaccines, including rabies vaccine, are designed to reduce infections. Logically, a rabies vaccine would work to lower rabies infections in both humans and dogs, which is a standard understanding of vaccines (prevention/reduction of disease).
• Option c: Vaccines do not increase infections; their purpose is the opposite, so this is incorrect.
• Option d: Rabies vaccine does have an effect on humans (preventing rabies infection), so this is incorrect.

Answer:

b. Rabies vaccine can reduce infections in humans and dogs
