For years, 94% to 95% of incoming kindergarteners were vaccinated against measles, tetanus and certain other diseases. But, the U.S. has begun to see a drop, with rates falling below 94% in the 2020-2021 and to about 93% in the 2021-2022 school year, according to a new U.S. government report.
Officials at the Centers for Disease Control and Prevention cite a combination of factors: pandemic disruptions in routine health care appointments, taxed school administrators and less confidence in vaccines.
