As of this week, more than 2 million Arizonans have received at least one dose of the COVID-19 vaccine. In neighboring Sonora, Mexico, large-scale vaccination hasn’t even started in the capital city. But older adults are set to begin receiving doses next week.

About 68,000 doses of the AstraZeneca vaccine are expected to be administered in Hermosillo next week to adults 60 and older.

They will be the first vaccines given to the general public in Sonora’s capital and most populated city, the last of the state’s 72 municipalities to inoculate non-medical personnel.

But there are only enough vaccines to provide the first dose to about two-thirds of those eligible in Hermosillo.

According to Mexico’s statistics agency, there are more than 325,000 people over 60 in the state. Fewer than half been vaccinated to date.
