An end to the pandemic could be in sight, after manufacturers announced that a leading Covid-19 vaccine is more than 90 per cent effective – a much better performance than experts had hoped for.

It is a major breakthrough in the battle against Covid-19, raising hopes that the shot could be available for use by the end of the year if given the green light by drug authorities.
But it has encountered unsurprising – and often deranged – resistance, with anti-vaxxers out in force online and linking the vaccine news to billionaire Microsoft founder Bill Gates.
