JAMA Network Open has published a new study showing that, from April 1, 2020, to February 27, 2023, in California, an estimated 146,210 COVID-19 cases were averted by vaccination in teens aged 12 to 15 years, representing a 37% reduction.
Eight more measles cases have been reported, putting the nation's total at 121 so far this year, the US Centers for Disease Control and Prevention (CDC) said in its latest weekly update. The number of affected jurisdictions remained the same, at 18.
The study was based on ED visits to nine US hospitals participating in the Pediatric Emergency Care Applied Research Network Registry from 2017 to 2022.
