Jellyfish around Malta

The jellyfish season has started here on Malta and swimming is almost impossible. There are quite a few tourists daring the jellyfish in the sea though and quite a few of them get stung. The jellyfish around Malta are not very dangerous but they hurt a lot and the sting can even become big scars. The skin gets a bad burn and the best thing to do, I found out after asking quite a few Maltese, is putting vinegar on the burn.
