England will require proof of vaccination for clubs, mass events

The big picture: Hours after people flocked to nightclubs early Monday morning, Johnson warned that proof of a negative COVID-19 test would soon "no longer be enough" to gain admission to such events, per Reuters.

• "I can serve notice now that by the end of September when all over 18s will have had their chance to be double jabbed, we're planning to make full vaccination the condition of entry to nightclubs and other venues where large crowds gather," Johnson told a press conference, Reuters reports.
• Britain's chief scientific adviser, Patrick Vallance, warned that nightclubs and other mass events could prove to be "super spreading events" that cause infections to rise further, per Reuters.

State of play: Other countries are also curbing nightlife in the wake of rising case numbers.

• The Netherlands almost fully reopened on June 26 and only two weeks later reimposed restrictions until Aug. 13, ordering nightclubs and discos to close amid surging case numbers.

Of note: Despite Johnson's warning to nightlife, he noted the government will not be imposing the same restrictions for pubs, per Reuters.
