We tend to follow the Australians somewhat, and on 25 May—so roughly two weeks ago—they put out a recommendation as well. This is what they said: "In this updated advice, an additional winter booster is now also recommended for other people at increased risk, to be given four months after the first booster dose. This applies to people aged 16 to 64 who have (a) a medical condition that increases the risk of severe COVID-19 illness, and (b) people with disability with significant or complex health needs or multiple comorbidities which increase risk of poor outcome from COVID-19."
