A client is seeking information about the varicella vaccine (Varivax) What should the nurse inform the client about the vaccine?

Choice A rationale:

(Incorrect) Shingles, caused by the varicella-zoster virus, can be transmitted through direct contact with the fluid from the vesicles (blisters) of a person who has active shingles. However, it is important for the nurse to provide correct information to the client.

Choice B rationale:

(Correct) Shingles can only occur in individuals who have previously had chickenpox. After a person recovers from chickenpox, the virus remains dormant in the nerve tissues. Later in life, the virus can reactivate, leading to shingles. It is crucial for the nurse to emphasize this point to prevent any misunderstandings.

Choice C rationale:

(Incorrect) While the shingles vaccine is effective in reducing the risk of developing shingles, it does not have a 100% efficacy rate. The vaccine can, however, reduce the severity and duration of the illness if shingles still occur after vaccination.

Choice D rationale:

(Incorrect) The herpes zoster vaccine (shingles vaccine) is not given to children under 10 years old. It is recommended for adults aged 50 years and older or for individuals with certain risk factors.

Choice A rationale:

Varivax is not administered as a single dose during adulthood. The vaccine is given as two doses, usually separated by 4 to 8 weeks, to ensure adequate protection.

Choice B rationale:

Varivax can reduce the risk of developing shingles, especially in individuals who had chickenpox and received the vaccine. While it may not completely prevent shingles, it can lessen its severity.

Choice C rationale:

This is the correct response. Varivax is a live attenuated vaccine, which means it contains weakened forms of the varicella-zoster virus that causes chickenpox. It stimulates the immune system to produce a protective response without causing the disease.

Choice D rationale:

Varivax is not recommended only for healthcare workers. It is recommended for certain groups, including children, adolescents, and adults who have not had chickenpox or received the vaccine. Healthcare workers might be among the targeted groups due to their increased risk of exposure, but it is not limited to them.
