Really? This doesn't look like good news to me. It's fairly positive on the effectiveness of boosters, but negative on the original doses. That would still suggest a COVID spread through the vaccinated population (the bulk of the population) with vastly less social distancing that the first year of the pandemic. The US and Europe will not get boosters to even 40% of the population before the new wave's peak.

It's an assurance that the current vaccines work + less severe cases/fatality compared to other variants. Good enough for the bulls to stay bullish.
