1. The Vaccines for Children (VFC) program is a federally-funded program that provides free vaccines to which population?
The VFC program provides free vaccines to children who are Medicaid-enrolled, uninsured, underinsured (for vaccines not covered by insurance), or American Indian/Alaska Native.
2. What minimum distance should vaccines be stored from the walls, floor, and ceiling of a refrigeration unit to ensure proper air circulation?
CDC recommends storing vaccines at least 2 to 3 inches from the walls, floor, and ceiling to allow cold air to circulate and maintain even temperatures.
3. A healthcare provider is preparing to administer IM vaccines to a 6-month-old. Which site is preferred?
The anterolateral thigh is the preferred IM injection site for infants because the muscle mass is larger and the risk of nerve or vascular injury is lower.
4. When administering multiple vaccines simultaneously at the same visit, injection sites should be separated by at least:
ACIP recommends injection sites be at least 1 inch (2.5 cm) apart to allow monitoring of site-specific local reactions from each individual vaccine.
5. A 65-year-old patient is due for pneumococcal vaccination and has never received any pneumococcal vaccine. What is the current ACIP recommendation?
ACIP recommends PCV15 followed by PPSV23 one year later, or a single dose of PCV20, for pneumococcal-naive adults aged 65 and older.

Water bottles serve as thermal mass (buffer), stabilizing temperatures and slowing temperature rises during power outages or door openings.
