Colorado kids catching up on routine vaccinations, but still below pre-pandemic levels

Vaccination rates have dropped across the country and worldwide, giving viruses more potential hosts and chances to spread, said Dr. Sean O’Leary, ACCORDS investigator and an infectious disease pediatrician at Children’s Hospital Colorado. While diseases like measles no longer circulate in the United States under normal circumstances, they’re more common in other parts of the world, and unvaccinated travelers could bring them back, he said.
