CDC study finds Pfizer-BioNTech COVID vaccine provides high protection against hospitalization in adolescents

New research from the Centers for Disease Control & Prevention (CDC) suggest vaccines are highly protective against severe acute respiratory coronavirus 2 (SARS-CoV-2). Two doses of the Pfizer-BioNTech vaccine showed a 93% effectiveness against hospitalization. The findings add to a previous clinical trial that found vaccinated adolescents with 100% protection against SARS-CoV-2 infections.
