WHO: “Interim statement on booster doses for COVID-19 vaccination” — Boosters are dubious for general use, should be targeted


Real science is never settled, and anyone who has certainty on such things is not qualified to discuss it.

Very satisfying to see some level of disagreement/debate over vaccination and boosters, even if the rationale behind it is itself worthy of debate.

WHO: Interim statement on booster doses for COVID-19 vaccination

2021-12-22. Emphasis added.



...In the context of ongoing global vaccine supply constraints and inequities, broad-based administration of booster doses risks exacerbating vaccine access by driving up demand in countries with substantial vaccine coverage and diverting supply while priority populations in some countries, or in subnational settings, have not yet received a primary vaccination series.  

Introducing booster doses should be firmly evidence-driven and targeted to the population groups at highest risk of serious disease and those necessary to protect the health system.  To date, the evidence indicates a minimal to modest reduction of vaccine protection against severe disease over the 6 months after the primary series. Waning of effectiveness against all clinical disease and infection is more pronounced. Duration of protection against the Omicron variant may be altered and is under active investigation. Evidence on waning vaccine effectiveness, in particular a decline in protection against severe disease in high-risk populations, calls for the development of vaccination strategies optimized for prevention of severe disease, including the targeted use of booster vaccination.


WIND: the White House calls for all-out boosters, while the WHO doubles-down on its skepticism of widespread boosters.
