The Mail on Sunday, citing a "government source", reports that for Covid travel passes to remain valid, people will have to ensure that they have had a full initial course of a recognised Covid-19 vaccine – such as the Pfizer, AstraZeneca and Moderna jabs – and any available booster jabs.
"The assumption is that you will be required to have the most up-to-date health passport," the source told the Mail on Sunday. "So if the advice is to have a booster six months after your second jab, then that is what you’ll need."
