Just did a quick google, if it's made with pasteurised eggs it's fine to eat. Hellman's is made with pasteurised egg so that's fine.
I have mayo nearly everyday, couldn't live without it 😅
Most mayo in the UK is pasteurised, in fact any dairy product sold in the UK must state clearly on the packaging if it is not pasteurised, so you’re all good😊
I have the hellmans plant based mayo & it’s really good. Maybe this is an option for others.
I literally did not know we weren’t allowed to have mayo
