In Australia it appears they're changing public messaging on vaccination for <30 yrs due to increased risk of myocarditis and lack of notable benefits[1]:

"One of the nation’s top advisers on vaccination says it is unlikely young people under 30 will be approved for fourth doses, as Australia turns its attention to antiviral access to tackle yet another Omicron wave."

"Former ATAGI co-chair and current member Professor Allen Cheng said the increased risk of myocarditis and the lack of notable benefit from additional boosters meant it was likely the recommended vaccine schedule for younger people would remain as is. Some are approaching a year since their booster shot."
