There's currently an entry ban from non-EEA countries into Sweden. It's due to expire on the 31st October, but it has been extended before and I find it likely that it will be extended again.
If I'm from the UK and want to go to Sweden, I would need to be in one of their exemptions. However, the page also states that Nordic countries (inc. Denmark) are exempt, and they only apply these regulations according to the last country you entered from. Denmark does not appear to have any entry ban and does not require a COVID test for vaccinated travellers (UK is an orange country under their system).
If this is the case, could I not just fly from the UK to Copenhagen, and then transit into Sweden either by plane to Stockholm or Øresundståg (etc) to Malmö? Is this legal, and would any checks at the borders be faced beyond the usual security/passport?
Reading the page seems to indicate it would be fine, so apologies if this is a silly question, but I want to be sure I'm not missing anything before booking. Also, if the 'entry ban' is circumvented this easily, then what purpose does it serve exactly (other than forcing people to take more stops on their journey and inevitably mingle with more people as a result)?
