COVID booster shots are now open to adults vaccinated 6 months ago

by By Bay City News Service

Bay Area public health departments have expanded their COVID-19 booster vaccine eligibility following directions from the state not to turn away patients who want an extra shot.

In a letter to health care providers dated Nov. 9, state Public Health Officer and Department of Public Health Director Dr. Tomas Aragon told health care providers that they should allow patients to "self-determine their risk of exposure" to the virus if they are seeking a booster dose.

The letter also reiterated that only adults who had their second vaccine dose more than six months ago or their single Janssen/Johnson & Johnson vaccine dose more than two months ago are eligible for a booster.

"The patient's assessment of risk exposure may include, but is not limited to, those who work with the public or live with someone who works with the public, live or work with someone at high risk of severe impact of COVID, live in geographic areas that have been heavily impacted by COVID, reside in high transmission areas, live in a congregate setting, experience social inequity or other risk conditions as assessed by the individual," Aragon said in the letter.

Health care providers are also encouraged to proactively encourage a booster for people ages 65 and older, people who have underlying medical conditions and people who received the J&J vaccine.

While the three available vaccines remain highly effective at preventing serious COVID-19 illness and death, public health officials at all levels have argued that preemptively boosting the immune responses of those at particularly high-risk for serious illness, such as immunocompromised people and nursing home residents, will maximize protection against existing and potential variants of the virus, which could become more contagious and even circumvent vaccine protections.

The functional expansion of eligibility to all California adults goes beyond recommendations from the Centers for Disease Control and Prevention, which only suggested boosters for people ages 65 and older and adults who live in long-term care settings, have underlying medical conditions or who live or work in a "high-risk setting."

In the Bay Area, public health officials have acknowledged that the federal definition of what constitutes a high-risk setting is vague, and residents should talk to their health care provider if they are unsure whether they qualify.

"If you look at the CDC guidelines, and you drill down to the various groups, what you end up with is the recognition that pretty much everybody is eligible," Santa Clara County Public Health Officer Dr. Sara Cody said in a briefing last week.

Cody went on to say "there were two main groups for whom the (booster) vaccine was really urged — the 65-and-ups, (people) living in a long-term care facility, etc., etc., etc. — but I think what the public heard was 'I have to be 65 otherwise I shouldn't get a booster,' and that's not correct."

Officials in multiple counties have also said it's unclear whether residents have even been turned away when seeking a booster dose.

Public health officials have also noted that booster vaccine uptake has not been as widespread as that of the initial vaccine series.

Cody said only about 20% of the roughly 1 million Santa Clara County residents eligible for a booster dose have received one.

"I think there's been quite a bit of complexity," in the booster rollout, she said. "And that's why we want to boil it down now and make it quite simple and let the public know that pretty much everybody is eligible for a booster, and there's lots of benefit from a booster."
