With some 'more open to conspiracy theories,' vaccination rates of English Premier League players remain shrouded in mystery

According to Liverpool manager Jurgen Klopp, 99% of his squad has been vaccinated.

(CNN)While the likes of the NFL are leading the way in public vaccine advocacy and transparency -- the league said it had reached a vaccination rate of over 90% among players by late September -- the uptake among footballers in the English Premier League remains shrouded in mystery.

The Premier League regularly releases details of how many players and club staff have been tested for Covid-19 and the number of positive tests, and some individual teams have disclosed vaccination rates, but the league declined CNN's requests to comment on the record for this story regarding vaccination data of players at its 20 clubs.
The BBC reported that in an email sent by the Premier League to its clubs in September the organization said: "Only seven clubs' squads are more than 50% fully vaccinated, so we have a way to go.
    "It is increasingly clear that full vaccination will be the key criteria for government and health authorities, in terms of international travel and potential Covid certification at large-scale events."
      CNN has been unable to confirm the authenticity of the letter.
        Currently, 85.4% of the UK population aged 12 and over has received at least one dose and 78.4% has received two doses.
        "We are considering if and how best we can 'reward' those squads/players who are most Covid-compliant and who have opted to be vaccinated," the letter reportedly said.
          Former Chelsea player Tammy Abraham, who now plays for AS Roma, says he has been vaccinated.

          'A bit of confusion'

          The England national team is involved in a World Cup qualifying game against Andorra on Saturday and ahead of that match Tammy Abraham, who plays for Italian club Roma, became the first England player to confirm he had taken the Covid-19 vaccine.
          England manager Gareth Southgate, speaking ahead of the Andorra game, said some of players were "more open to some of these conspiracy theories" surround Covid-19 vaccines "because they are reading social media more, they are perhaps more vulnerable to those sort of views."
          "From what I can see there is a bit of confusion around. And there are several different threads there to why they are choosing to be jabbed or not to speak publicly about it," Southgate told reporters.
