Vaccine and Shingles

The introduction of the varicella vaccine has led to a significant decline in chickenpox cases, with reductions of 95% to 97%, even among adults and infants. This decline supports the idea that natural exposure to chickenpox acts as a booster for immunity against shingles, challenging earlier predictions of increased shingles cases due to vaccination. Insights reveal that community exposure has decreased, benefiting those who were never vaccinated.
