Associated Press New Mexico is now administering the Pfizer vaccine for COVID-19 to children ages 12 to 15, as state health officials pushed Thursday for more people to get vaccinated. The move by the state Health Department follows authorizations this week by the federal Food and Drug Administration and the Centers for Disease Control and Prevention. The state is encouraging families to register children on its vaccine website. The expanded availability applies only to the Pfizer vaccine, which until now was only available to people ages 16 and older. The Moderna and Johnson & Johnson vaccines are authorized for people 18 and older. State officials say more than half of eligible residents are now considered fully vaccinated.
