Unlike past years, access to COVID-19 vaccines has become complicated in 2025, largely because federal guidance does not recommend them for nearly everyone this year as it had in the past. Arizona, Maine and North Carolina are likely to come off that list as the new orders take effect there. Friday’s orders are expected to change the policy in all three states where they were put into place. While most Republican-controlled states have not changed vaccine policy this month, the inoculations are still available there under existing policies. In past years, the federal government has recommended the vaccines to all Americans above the age of 6 months.
