The evidence so far suggests this wave could be a shorter and smaller version of the Omicron BA.5 wave.
Several countries are preparing to distribute Omicron-adapted COVID-19 boosters. What does this mean for Australia?
New research estimates proportion of the adult population in Australia with evidence of past infection following the Omicron wave.
Variant-specific vaccines would undoubtedly increase immunity. But waves of new variants would engulf the population faster than these vaccines could ever be deployed.
Given the Omicron variant has already spread beyond southern Africa, a ban on travellers from those countries will slow the spread and buy crucial time, but won’t stop this strain in its tracks.
