I suggest doing some online research. You're going to see lots of conflicting information.
On one hand it prevents certain cancer causing strains of HPV. On the other hand it DOESNT prevent certain cancer causing strains of HPV. So will your child be protected from HPV or cancer? Some.
Food for thought...
About 4,200 women a year die from cervical cancer. (It's probably safe to say lots of those women avoided yearly exams) About 360 deaths from penile cancer.
44,000 a year people die from drug overdose.
620,000 people die every year from heart disease
Almost 3300 people die in car crashes every single day.
I believe sometimes these drug companies feed our fears and manipulate our protective natures. They are making HPV out to be some killer epidemic when quite honestly...it's just not. They will rake in billions on this vaccine and will probably only make a small dent in the death toll. Idk. Maybe that "one less" marketing really speaks to you.
Only you can decide.
Do your research.
I personally am not vaccinating my teenage son for this. For the record all my kids are up to date on the recommended vaccinations. This one just isn't on my radar.
Best of luck.
