On September 20, Pfizer announced that the COVID-19 vaccine it is designing to be administered to children has been proven to be safe — and moreover yielded a robust immune response in children between the ages of 5 and 11. The announcement came after the company released its Phase 2 and 3 results for children in this age group. Following this much-anticipated announcement, the company’s next step is to seek emergency authorization from the U.S. Federal Drug Administration and submit their findings. If authorization is given swiftly, children as young as five could be eligible for Pfizer’s COVID-19 vaccine by Halloween.
