What is the correct dose and route for administering the HZV and IIV vaccines to a 60-year-old woman?

The correct dosing and route for administering the herpes zoster vaccine (HZV) and the inactivated influenza vaccine (IIV) is significant for ensuring effective immunization in adults, particularly in those aged 60 and older. HZV is recommended as a single dose of 0.65 mL administered subcutaneously (SC), while IIV is typically given as 0.5 mL via intramuscular (IM) injection.

Choosing 0.65 mL SC for the HZV ensures that the vaccine is delivered in a manner that maximizes its efficacy, as the SC route is recommended for the herpes zoster vaccine to stimulate an appropriate immune response. The 0.5 mL IM route for IIV is also the standard practice, as this method allows for better absorption of the vaccine and a robust immune response.

Incorporating these routes and dosages aligns with the most current guidelines for these vaccines, aimed at this age group, where both viruses posed significant health risks. The importance of adhering to specific administration routes cannot be understated, as it directly influences vaccine effectiveness and the prevention of related conditions.
