According to data given by the Centers for Disease Control and Prevention (CDC) on May 23, 2021, at least 25 states, plus Washington, DC, have fully immunized almost half of their adult citizens. Furthermore, the CDC has fully vaccinated more than half of the adult population in Connecticut, Maine, Massachusetts, and Vermont. The immunization campaign is having an impact. In September, New York City Mayor Bill de Blasio announced that the city’s public schools would return to all-in-person learning, with no remote choices. Face masks would continue to be required in schools, according to Meisha Porter, the Chancellor of the New York City Schools. Regardless of immunization status, Gov. Phil Murphy said on May 24, 2021 that mask-wearing and social distance restrictions would be abolished in New Jersey, except for certain designated situations. He pointed out that if a company wants to, it may make staff and customers wear masks. Meanwhile, Governor Gretchen Whitmer of Michigan issued additional laws and guidelines for returning to work, including the ability for fully vaccinated staff to avoid wearing face masks and social isolation. The state’s immunization rate has surpassed 55 percent, according to Whitmer.
