Mary Chin, the chief executive officer of the Asian American Civic Association, was the first to receive her shot.

“I want to tell everybody to not be afraid,” Chin said about the vaccine.

“I also think it’s important to educate everybody that [the pandemic is] not over. Even after the vaccine is distributed, we really need to keep masking and keep washing our hands and keep distancing,” she added.
