In fact, during the month of June, 20% of all newly reported COVID infections in the county occurred among people who had been fully vaccinated. That was up from 11% in May and 5% in April. But Public Health Director Barbara Ferrer said the increase is normal given the continued rise in the number of people who are getting fully vaccinated.

She also stressed that fully vaccinated people who become infected generally have extremely mild cases — a benefit the vaccines have always promised.

“Very few of them ended up hospitalized, and even smaller numbers ended up passing away,” Ferrer said. “So yes, if you are fully vaccinated you have a lot of protection, which is what the vaccines have always been best at — protecting people from serious illness and death. And these vaccines, even with the Delta variant, are holding up really well.”
