Single Australians looking for sex or love will soon stand out from the competition if they've been vaccinated against Covid-19. Dating app Bumble announced it will roll out a new feature this week enabling users in Australia and New Zealand to add a "vaccination badge" to their profile if they've received a Covid-19 jab. Competitor Tinder says it looks forward to "making [vaccine] badges available soon" in Australia too. A Bumble representative says it will not independently verify the vaccination status of those who claim the badge, meaning the system will rely on user honesty. The dating app says it decided to launch the feature after a recent survey revealed a "45% increase in users asking potential dates if they had the vaccine or have Covid symptoms". It's not just in Australia that dating apps are encouraging users to boast about their vaccination status.
