Navajo Nation officials said they will participate in the Pfizer-BioNTech COVID-19 vaccine trials amid a steady decline in coronavirus cases.
The tribe’s territory once had the highest coronavirus infection rate in the country, but has since seen a substantial decrease in community spread, The Arizona Republic reported. Navajo officials reported zero new confirmed cases on Sept. 8 for the first time since the pandemic hit the reservation.
As of Saturday night, there had been 9,969 confirmed cases and 530 confirmed deaths from the coronavirus in the Navajo Nation, according to its Department of Health.
The number of infections is thought to be far higher because many have not been tested, and studies suggest people can be infected with the virus without feeling sick.
The vaccine trials will be conducted at health care centers across the Navajo Nation. Participation is voluntary.
