@goatsarah @avuko @bicmay I don't know how it works in Portugal. Do you still have an NHS GP at all, or could register as a temporary patient? Here, you'd be eligible to get the second dose of a measles-containing vaccine (they'd give you MMR). If they argue, you can direct them to NHS guidance (https://www.nhs.uk/conditions/vaccinations/mmr-vaccine/) under 'When older children and adults should have the MMR vaccine'
