More good news in the fight against the coronavirus: Pfizer and BioNTech's COVID-19 vaccine is 100% effective against the virus in children ages 12 to 15, the companies announced today. In a placebo-controlled trial of 2,260 adolescents, none of the participants who received the real vaccine developed COVID-19, the companies said. Eighteen adolescents who received placebo, or fake, doses became infected with the virus, they said. The company hopes to start vaccinating children ages 12 to 15 before the start of the next school year. Experts say that ensuring vaccines are safe and effective in children will be crucial to ending the pandemic. Although children are less likely to die of COVID-19, it’s still possible for them to get sick and spread the virus.
