England's deputy chief medical officer has warned that people will need to manage the risks of Covid in the "long term" - as experts wait to see how long vaccines give protection for.
Prof Jonathan Van Tam urged people to "be cautious" during this afternoon's press briefing from Downing Street. He said that work is still ongoing to determine how much more transmissible the Indian coronavirus variant is, and admitted scientists still do not know how long vaccines will protect people from the virus for.
Prof Van Tam urged people to try and meet "in smaller numbers" and "take it steady" after rules were further relaxed earlier this week.
