When Mary turned 64, she was diagnosed with type 2 diabetes and received PPSV23. What represents appropriate pneumococcal coverage for her?

To understand the appropriate pneumococcal coverage for Mary, it’s important to recognize the recommended guidelines for pneumococcal vaccination in adults, particularly those with certain health conditions like type 2 diabetes.

The correct answer involves first administering the PPSV23 (Pneumococcal polysaccharide vaccine) at age 69 followed by PCV13 (Pneumococcal conjugate vaccine) at age 70. This approach is consistent with the recommendations for individuals who have specific health conditions that increase their risk of pneumonia and other pneumococcal diseases.

For adults aged 65 or older, it is advisable to use both vaccines to ensure comprehensive protection. The general recommendation is to give PCV13 first, followed by PPSV23 at least one year later for those who have never received either vaccination. However, given Mary’s previous vaccination with PPSV23 at age 64, she requires an appropriate timing for the administration of PCV13 alongside PPSV23.

In the correct strategy, administering PPSV23 first with subsequent administration of PCV13 supports the need to enhance the immune response against serotypes covered by both vaccines. Administering these vaccines according to the recommended intervals and sequence maximizes their efficacy and provides
