I'm living in Sweden and my girlfriend has been infected twice about a year apart. So yeah it seems like the passage of a year and the combination of new strains is enough for this to happen. Also unfortunately her second case was definitely worse than the first (which wasn't exactly fun either). It's a shitty disease.
