Dr. Celia Quinn explains that a combination of factors led to the delay in vaccination rates post-pandemic, particularly among four to six-year-olds.

• The most significant gap in vaccination rates is found among children aged four to six, who were infants to three years old during the pandemic's peak.
• There were considerable barriers to vaccine access during the pandemic, which have since been somewhat addressed for the 0 to 2 age group, allowing their rates to improve.
• However, four to six-year-olds still face challenges in accessing the full catch-up vaccination schedule.
• As vaccinations become required for entry into pre-K and kindergarten, it is expected that these rates will improve, helping to close the gap.
