Stir the lime juice, sugar, vanilla and ½ cup water together in a large pitcher until the sugar is dissolved. Chill thoroughly. The syrup may be made up to several hours before serving.
Just before serving, pour the sparkling water into the syrup and serve, with ice and a lime slice tucked into each glass if you like.
