Here is material from the mainstream Left-wing on-line news the Guardian.com, reporting on the splendour of Covid booster shots. Yes, truly magnificent, but why are the boosters needed, why isn’t one jab of the magic potent enough? Because “The finding suggests that protection against infection, with or without symptoms, starts to wane several months after full vaccination, though other studies show that vaccine protection against hospitalisation and death is far more robust.
“The possible increase of breakthrough infections over time reinforces the need for a booster programme,” said Paul Elliott, head of the React study and professor in epidemiology and public health medicine at Imperial. “It’s an incentive for people to get their booster dose when it becomes available to them,” added Prof Christl Donnelly, a statistical epidemiologist on the study.” So, one jab does not do it. Why should two? Israel is up to four now.
