A sixteen-year-old high school student in the Bronx, New York, Ariel Quero, was vaccinated on Tuesday in part to convince her doubtful family that the vaccine is safe for the rest of the family. "I'm feeling pretty good," Quero said moments after she received her first shot of the Pfizer vaccine. "The reason I got vaccinated today is so I can show my parents and the rest of my family that the vaccination isn't bad and that they can see that me getting the vaccination, they think 'oh you are going to get sick' when really getting vaccinated is just simply protecting yourself from COVID so I can show that I'm protected and the vaccine is truly what leads to our safety right now." Fourteen-year-old Giret Medina, a high school sophomore when school starts in a few weeks, says it was partly the convenience of having the vaccine available in the school auditorium that convinced her to get the shot. Before being vaccinated, students had a chance to ask Schools Chancellor Meisha Porter questions about the vaccine. The push at New York City schools to get students vaccinated comes as the Centers for Disease Control and Prevention on Tuesday reversed course on some masking guidelines. The agency announced new recommendations that even vaccinated people should return to wearing masks indoors in parts of the U.S. where the coronavirus is surging. Scientists cited new information about the ability of the delta variant to spread among vaccinated people. The CDC also recommended indoor masks for all teachers, staff, students and visitors to schools, regardless of vaccination status. The new guidance follows recent decisions in Los Angeles and St. Louis to revert to indoor mask mandates amid a spike in COVID-19 cases and hospitalizations that have been especially bad in the South.
