The All England Lawn Tennis Club (AELTC) has given Djokovic and other unvaccinated players the go-ahead to compete at Wimbledon.
The AELTC added that a Covid-19 jab is not required to enter Britain.
"Whilst of course it is encouraged, it will not be a condition of entry to compete at the championships this year," AELTC chief executive Sally Bolton said, according to the ABC.
The Wimbledon chief also confirmed that players would be able to choose their own accommodation once again. This change comes after the 2021 grand slam saw players ordered to stay together in a central London hotel.
Wimbledon will take place from 27 June to 10 July.
