Are we nearly there yet? Not quite, the vaccine is just round the next corner

The growing stream of positive news about the effectiveness of candidate C19 vaccines is indeed phenomenally good news. Yet the journey to the good type of herd immunity based on an immunised population will be long and winding.  and yes we really are nearly there but how nearly is near. With a second RNA vaccine announced to have 95% protection and several others in the pipeline none of which suffer from the same cold-chain logistics challenges in principle, the path to population immunity is clear. Yet there remains an enormous challenge to get sufficient uptake for things to be getting back to normal by this time next year and indeed at all.  As the inventor of the Pfizer vaccine noted 80% must be vaccinated by autumn to beat major outbreaks next winter.  This is a very tall order.  Further, there are huge trust issues among those who are not naturally classical anti-vaxers. Despite the tragically high levels of deaths and risk in the US, a recent poll...

Some have doubted the figures but the success of other large south Asian nations to manage the pandemic suggests their success is real.  New Zealand, a European western-style democracy has also a very good record in delivering eradication but its size and geography make it an exception to any rule. Without the advantages of a small remote island nation with a leader who acted fast and was able to garner a large national consensus, it is instructive to examine the levers China employed to achieve it.  A short article in the Lancet set out the key factors: 

  • speed of action, 
  • use of draconian propaganda (drones equipped with echoing loudspeaker berating non-compliers - the degree to which this actually happened, or was used on social media as a...
