I could probably get into a debate about the ad, but I'll just say...I think it's a good idea for the company to get the word out there that such a vaccine exists, even if it's most effective for women who aren't yet sexually active, and haven't been exposed to the strains of HPV that the vaccine protects against. It's always a good idea to ask your doctor if you need a medication, but I think it's good to let women know that, for the first time, there is SOMETHING that can help protect against cervical cancer. I know I'll be getting the vaccine soon.
I also don't like to take medicine unless necessary. I tell people I have a cold, and they all say, "Oh, are you taking something for it?" I never take cold medication; I believe it'll run it's own course. I take Tylenol or Motrin if I need to, or antibiotics if I have to. My mom is a doctor, and she doesn't believe in over-prescribing. I tend to follow what she thinks.
Anyway...drug companies, same as any other, want people to use their products. Their ads reflect that. I try not to get too worked up over it.
