Suwan Keo made sure his dad and grandparents got their boosters.
"Very important, especially because we're planning to travel internationally," he said.
About 200 people a day come in to get shots at the UCSF Fresno drive-through testing and vaccination site in northeast Fresno.
Dr. Kenny Banh says 98% of them are getting boosters. But he'd like to see more people get their first dose of the vaccine.
"It is a little frustrating," he said. "I have to be honest with you because I'm really excited about getting people boostered and trying to increase their protection, but we're missing a whole chunk of people that have no protection whatsoever."
At this point, 56% of Fresno County residents are fully vaccinated.
63% have had their first dose but it has been a struggle to raise those figures.
"We're just getting a trickle of people getting first dose vaccines so whatever people are vaccine-resistant or vaccine-hesitant, trying to get those last groups that are really, really concerned about this that are really a high risk for both spreading as well as high of injury themselves, it's really hard to get," Dr. Banh said.
The CDC recommends kids between 12-17 get their booster shots as well.
