It makes it unambiguously clear that this age group should get vaccinated. Unfortunately only 33% of this age group has completed the primary series. I hope grifters like Vinay Prasad can live with themselves.
Children who received the Pfizer vaccine had lower odds of infection, disease, hospitalization, and MIS-C. And the myocarditis rate was miniscule.
As I have mentioned as well vaccine-associated myocarditis is short-lived and self-limiting (resolves fully on its own), unlike the viral myocarditis from coronavirus infection, which is more severe and has a worse prognosis.
Paul Offit has a great accompanying editorial making the case for vaccination of this age group.
As Offit notes in the editorial, while it is true that coronavirus is generally less severe in children than in adults, for children it is a more severe virus compared to other childhood viruses:
"Every year, prior to the availability of a vaccine, 3 children died of hepatitis A virus, 8 children died of meningococcus, 16 children died of varicella, 17 people of all ages died of rubella, and 20 children died of rotavirus. Between October 2020 and October 2021, 66 children aged 5 to 11 years died of SARS-COV-2 infection."
