President Andrés Manuel López Obrador publicly received a booster shot during his daily press conference on Tuesday, Dec. 7, 2021.

Starting Wednesday, booster shots became available in neighboring Sonora, Mexico. The so-called vaccine reinforcement campaign started in the capital Hermosillo.

The first booster shots in Sonora are being administered in Hermosillo until this Sunday to seniors aged 60 and older who were fully vaccinated at least six months ago.

In Mexico, the AstraZeneca vaccine is being used for all boosters shots, regardless of which vaccine the person originally received.

"You all know that during the winter season, respiratory problems increase," Sonoran Gov. Alfonso Durazo said this week, in a message urging Sonorans to get booster shots, as well as first or second doses for those who haven’t yet been fully vaccinated. "that's why I'm calling on all of you to get vaccinated."

Durazo also said everyone should receive a flu shots and continue following safety precautions.

"Now is not the time to declare victory. We should continue following prevention measures: face masks, social distancing, hand sanitizer, etc.," he said. "It's for your own good."

Data shows that COVID-19 cases are on the rise again in Sonora, signaling a possible fourth wave as the holidays approach.
