Its protecting you from Cervical Cancer which is caused by HPV (human papilloma virus) There are 36 (I believe) strands of it. HPV is the deadliest STD-and the most common.
Even if you're not sexually active, even if you're saving sex till marriage, that doesn't mean the person you marry has. THEY could have HPV and they could infect you. Cervical cancer can kill you, but if it doesn't kill you, it could prevent you from ever having children of your own.
This shot only fights 4 strands of it. But it fights the 4 leading cancer causing strands.
If you're not sexually active, I still highly suggest you get this. You never know what might happen down the road, but this could help you keep yourself safe.
This is not a birth control method, and it will not protect you against any other stds. Use this shot, with the pill and/or condoms. (I suggest and. both are 99.9 percent effective, but do you want to be that .1 percent? Double protection is better than none at all)
If you are sexually active, GET THIS SHOT. You and your boyfriend may be faithful, but how do you know who he had sex with before you two got in a relationship, and who did that person have sex with? Youre still at risk.
Its a needle, yes its scary, yes it hurts, but it will only hurt for a second, and I can promise you it hurts less than cervical cancer does.
