A 12-month-old HIV positive infant should receive the varicella vaccine if they are not immunosuppressed. Is this true?

In the context of vaccine administration for a 12-month-old HIV positive infant, the statement holds true because the current guidelines from health authorities suggest that if an HIV-positive child is not immunosuppressed, they can receive the varicella vaccine. The varicella vaccine is live-attenuated, which means it contains a weakened form of the virus; thus, it is generally not recommended for immunocompromised individuals due to the risk of adverse reactions.

In the case of an HIV-positive infant, if their immune function is stable and not significantly compromised, the vaccine can be safely administered. This is important for preventing varicella (chickenpox), which can be more severe in those with weakened immune systems. Ensuring that these children are monitored for their immunological status is essential for deciding their eligibility for live vaccines, but if they are confirmed to be not immunosuppressed, then vaccination is appropriate and beneficial for their health.

The other options suggest circumstances where vaccination would either not occur or be limited in scope, which does not align with the established guidelines for healthy and non-immunosuppressed HIV-positive patients.
