CDC-Abt Study Shows Pfizer Vaccine Is Moderately Effective for Children

More than 300 news organizations, including CBS and Forbes, quoted Abt’s Lauren Olsho explaining the benefits of our PROTECT study for the CDC, which gathers and tests nasal swabs weekly from children, regardless of whether they had COVID-19 symptoms. “Without regular weekly testing you will miss many infections, particularly for kids, who often have mild symptoms,” said Olsho, the study’s principal investigator. Other pediatric vaccine studies captured only symptomatic cases, and with more home testing, studies like Abt’s are needed for a comprehensive view of vaccine effectiveness, she noted.
