Although the Centers for Disease Control and Prevention issued new guidelines last month that indicated schools could reopen before all teachers receive the Covid-19 vaccine, the agency recommended that districts adhere to strong hygiene, masking, physical distancing and sanitation guidelines. 

All of that takes funding — and lawmakers are attempting to provide it. The latest Covid-19 relief bill signed by President Joe Biden on Thursday allocates nearly $170 billion to K-12 schools and colleges to help fund initiatives such as installing ventilation systems, reducing class sizes, implementing social distancing processes, hiring additional staff and purchasing personal protective equipment for teachers, staff and students.
