Big events like Premier League games could be open only to fully vaccinated people starting in October according to government plans.
Talks are underway with the Premier League to discuss whether fans who have not received both blows could be banned from entry, according to the PA news agency.
The ruler could also be used for lower divisions and other sports, and for seated events with a capacity of more than 20,000 people.
For events without seats, such as concerts, the threshold could be as low as 5,000 attendees.
A government source said: “It is important that fans can continue to watch sporting events throughout the fall, so we are exploring the role vaccines could play in this.”
“This will not only allow stadiums at full capacity, but it has the added benefit of incentivizing people of all ages to go and receive their jab.
It’s unclear if a recent negative test could allow entry to soccer games, but this has been ruled out for nightclubs.
Shadow sports secretary Jo Stevens said: “Insisting on vaccine passports less than a month before the start of the season will cause major disruptions, especially for clubs at the bottom end of the pyramid.
“Labor has been clear that using the COVID vaccination status alone will exclude those who cannot be vaccinated or who have not received the injection due to delays.
“Being hit twice does not prove that you are not a carrier of the virus.
“The entrance tests to the places would be more efficient.”
The English Football League declined to comment, but it is understood that contingency plans are being discussed to deal with any changes in government policy.
The government’s top scientific adviser, Sir Patrick Vallance, has previously said that nightclubs could be “high-profile events,” but it is unclear if there are similar fears about soccer matches.
However, there were concerns about fans traveling to London during Euro 2020, and figures from Public Health Scotland showed nearly 1,300 coronavirus cases related to fans heading to the capital for group stage matches.
On Saturday it was announced that people in front-line roles such as police, firefighters and the Border Force you will be able to avoid quarantine, regardless of the vaccine status – if they are a close contact of a positive COVID case.
It is part of the government’s efforts to deal with the current situation where certain sectors are left with a serious shortage of staff due to workers being told to isolate themselves because they have come into contact with someone who has COVID.
The NHS COVID-19 app told more than 600,000 people in England and Wales to self-quarantine in the week ending July 14.
Emergency services workers and other critical personnel, including those in transport, freight and transportation, were already to be exempted from isolation, but only if their employers specified their names and criticized them twice.
They will now be able to participate in the program whether they are vaccinated or not, as new testing sites will be established.
Also on Saturday, the number of new COVID-19 cases in the UK fell for the fourth day in a row.
There were 31,795 new cases, compared with 36,389 cases on Friday and 54,674 infections on the same day the previous week.
