Omicron-based vaccines will roll out this fall
Source: Washington Post
This fall, vaccine makers will begin rolling out coronavirus booster vaccines tailored to fight the current version of the pandemic. Two days after outside experts voted in favor of a new vaccine adapted to protect against omicron, the Food and Drug Administration announced that the fall shots would include a component from BA. 4 and BA. 5, the omicron subvariants gaining ground in the United States.
The change shows the FDA trying to be more nimble in efforts to keep up with a changing virus. The precise formula has not been tested in people yet, but studies showed that vaccines tuned to fight a previous version of omicron modestly increased the short-term immune response in people compared to more shots of the original. The agency will depend in part on that data as it reviews the new vaccines.
It is quite possible that BA. 4 and BA. 5 will be eclipsed by new variants by the fall, but the hope is that a new shot will help broaden immunity, since they are closer to where the virus is today. For a year and a half, coronavirus vaccines based on the original version of the coronavirus have provided robust protection, particularly against severe illness.
But immunity tapers off over time, and the virus has proven wily, spawning a growing Greek alphabet of new variants that are more contagious and deft at slipping by people’s immune defenses. “As we move into the fall and winter, it is critical that we have safe and effective vaccine boosters that can provide protection against circulating and emerging variants to prevent the most severe consequences of covid-19,” the FDA statement said.

I saw an article early this morning where they were already freaking out in France where they are expecting to hit a peak of BA.4/5 cases in July.

France's new wave of COVID infections expected to peak end-July -scientist

PARIS, June 30 (Reuters) - A new wave in France of COVID-19 infections fuelled by emerging variants of the disease should peak towards end-July, the French government's top scientific adviser Jean-Francois Delfraissy said on Thursday.
"The peak is not yet here, this peak of infections will probably be for end-July," Delfraissy told RTL radio. "Then the BA.5 variant will reappear, if it is not overtaken by another variant ...in autumn," he added.
France reported new 124,724 coronavirus infections over the past 24 hours, against 77,967 a week ago.

The U.S. is averaging about 100,000 (reported) cases per day and we have about 5 times the population of France, so their 124,000/day is a big uptick for them.
This was the latest "Nowcast" from CDC on the variants circulating here -

between "boosters" (depending on whether it is for a first booster or second).
Here is CDC's webpage describing the timing (you would click on the row of the vaccine brand that you used or are interested in and it describes the timings between the initial series and then any later "boosters" ) -
