Celeste Lynch Lion’s Roar Staff People ages sixteen and up have been receiving the vaccine against the coronavirus for the last few months, however younger teens and kids have not been eligible to receive the vaccine. On May 10, 2021, the Food and Drug Administration approved the Pfizer vaccine for teens ages twelve to fifteen, making it the first vaccine to be approved in the US for this age bracket. Data from clinical trials performed by Pfizer demonstrates that 100% efficacy in young people between the ages of twelve and fifteen. The trials involved 2,260 people in this age group, and everyone tolerated the vaccine well. The Center for Disease Control has recently approved the administration of the vaccine to young people in this age group, meaning that vaccines will swiftly begin to be rolled out. The Biden administration claimed that a federal mobilization effort would begin once the CDC recommended the vaccine for teens this age. This FDA approval for the vaccine brings the US one step closer to herd immunity, and will speed up the process of reopening schools, and heading back to “normal”. This expansion of eligibility for the vaccine, will allow for 5% more of the population to be vaccinated, approximately 17 million people, meaning that 85% of the US population will be eligible for the vaccine against COVID-19, making the United States closer to herd immunity. Pfizer has said that it will submit its vaccine for emergency authorization in September for children from the ages of two to eleven. The FDA will also have a meeting of its Vaccines and Related Biological Products Committee to discuss the potential extension of emergency use authorization for children under twelve years old. As of yet, Pfizer is the only vaccine approved for people under the age of eighteen, as Modern and Johnson & Johnson have not submitted applications for emergency use authorization for those who are underage. So far, 45.8% of the US has received at least one dose of the vaccine. According to Anthony Fauci, 70-85% of the population would need to be vaccinated to reach herd immunity, making young people a priority for vaccination.
