TSAILE, Ariz. (AP) — A college on the Navajo Nation has accepted President Joe Biden's challenge to get students and others vaccinated against COVID-19 by July 4.

Diné College Incident Command Director Velveena Davis said COVID-19 remains a threat to the Navajo Nation, “so the college would like to do its part to expand the efforts of having our employees and students vaccinated.”

The college wants to ensure the safety and wellness of its campuses as they transition to in-person operations, Davis said.

The U.S. Department of Education on Thursday reached out to higher education institutions of behalf of Biden, asking them to play a role in reaching a 70% nationwide vaccination goal by July 4.

In another development, the Navajo Nation Council on Thursday approved a resolution to reopen tribal parks, businesses in the parks and the tribal zoo and museum

The resolution now goes Navajo Nation President Jonathan Nez, who has 10 days to act on the measure, the Gallup Independent reported.
