If the vaccine rollout allows us to return to some semblance of normality, then some of the most significant royal events of recent times will become public events, too. This year is big for royal anniversaries: the Queen will turn 95, Prince Philip will become 100 and in July, Princess Diana would have been 60. All three are expected to generate varying degrees of public celebration, depending on the progress of the vaccine.
