CV and mad panic behaviour

[Mav]

I understand why you would be concerned that promotion of new vaccines might undermine confidence in those that exist already. But the silver lining of the pandemic is that it has accelerated medical science in the way that wars have accelerated technology. The British were still flying biplanes at the start of WWII and by the end of the war they had jets. We've fast-forwarded through a decade of normal research into coronaviruses. It'll be interesting to see whether this ends up giving us better ways of suppressing the flu, for instance.

Stories like this are also a bit of an antidote to the pessimism of those who say that Covid will manage to evade vaccines, so why put your eggs in the vaccine basket. Yes, Covid may well mutate so that existing vaccines struggle to fight it (although recent articles suggest that there's reason to think Covid may find it hard to improve on Delta), but they can be tweaked or replaced by new vaccines or treatments.
