Is immunity from vaccines waning?

BBC World Service - More or Less, Is immunity from vaccines waning?

How worried should we be about declining antibodies? Plus life-threatening hotdogs.

Should we be worried that the protection against Covid-19 provided by the vaccines is going down? This worrying idea has been in the news recently, partly because of reports out of Israel. Last winter, Israel was one of the first to embark on a large scale vaccination programme of its citizens. But several months on, it’s now seen a sharp rise in the numbers of cases and hospitalisations. 

Which does raise a worrying thought: is the vaccine’s effect fading?
