Just as Pfizer announced a covid vaccine with great efficacy this week, a great piece I edited for Nature has been published about overcoming the hurdles to delivering such vaccines around the world.

The piece recommends 5 steps for the world to ensure equitable vaccine access.
Particularly interesting is their point that many nations don't have ANY adult vaccination programmes at present (not every country routinely vaccinates for seasonal flu, for example, and in some nations the only vaccines that an adult might get is during pregnancy). For those nations, ramping up to deliver a covid vaccine will be particularly challenging; the authors recommend practising with the seasonal flu jab, which sounds like an excellent win-win strategy to me.
