I was just reading about this a few days ago: https://arstechnica.com/science/2022...ver-ba-5-wave/

US COVID-19 cases are currently plateaued at a high level of around 117,000 new cases per day—but that's likely a significant underestimate given that many Americans are testing at home and not reporting their cases. Hospitalizations and intensive care admissions, meanwhile, are rising, with 17 percent and 21 percent increases over the past two weeks, respectively, according to tracking by The New York Times. Generally, the daily average of hospitalizations has more than doubled since the end of May, with the current average nearing 38,000.

On Monday evening, The Washington Post broke the news that the Biden administration is considering expanding eligibility of second boosters to include all adults. The report cited five unnamed officials with knowledge of the matter, who said that Jha and top infectious disease expert Anthony Fauci support the idea of expanding second boosters to all adults.

And the most important part here:

Jha and CDC Director Rochelle Walensky said repeatedly Tuesday that getting a booster now—or in two weeks or so—would not preclude getting a bivalent booster this fall. Their thinking is simply based on the time frame and anticipated interval for boosters. "As we've looked at the cadence of where we've needed to get boosts before, it's been four, five months," Walensky said. "We anticipate that that's going to be a similar cadence. We also really want to emphasize that there are many people who are high risk right now, and waiting until October/November for their boost—when, in fact, their risk is in the moment—is not a good plan," she added. "So, we really do want to say 'Now get your boost. We have every anticipation that the data will suggest that you will be eligible for a [bivalent] boost in the fall.' We will, of course, continue to evaluate those data."

TLDR: You/he/everyone who can should go ahead and get boosted now and should also get boosted when the fall boosters arrive. There's no good reason to wait.
