The Headline here buries the key findings: > A _two-shot_ course of Pfizer Inc.’s vaccine has just 22.5% efficacy against symptomatic infection with the omicron variant, _but can thwart severe disease_ and > boosters from AstraZeneca Plc and Pfizer/BioNTech SE improve protection against the omicron variant to as much as 75% in the early days after the shot There is also no reason to suppose that two doses, given a few weeks apart, are going to be a gold standard. Is a third shot a "booster" if it's a normal requirement? "Two shots, and done in 3 months" is not what happens with routine UK childhood vaccinations against Diphtheria, Tetanus, Polio.

That will come in time. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/899422/PHE_Routine_Childhood_Immunisation_Schedule_Jun2020_03.pdf https://assets.publishing.service.gov.uk/government/uploads/...
