Pfizer says kid-size doses of its COVID-19 vaccine are safe and nearly 91% effective at preventing symptomatic infections in elementary school children.

Gov. J.B. Pritzker issued an order over the summer requiring masks in school for everyone regardless of vaccination status.

"Our data clearly shows that vaccinations are making a difference and decreasing viral activity in Missouri. We are on the right track, and thanks to now three million Missourians, we are significantly reducing the threat COVID-19 poses to our state." 

There's been an error in the number of vaccinations reported to the federal reporting system. That means state and local numbers were affected as well.
