I just found out you can get this vaccine privately until you're 45. I feel really angry that this information wasn't made available when they made the vaccine available to school girls in 2008. I'd have gladly paid a couple of hundred pounds or however much it cost back then to get vaccinated. I thought it was only offered to school girls as it only worked if you started taking it before becoming sexually active. So I'm going to get it but does anyone know if it will be less effective given I'm almost at the age where you can't even get it privately? How does it work?
