is cervarix or gardasil really neccessary??

been wondering for some time.. to take or not to take.. if take, which brand.. seems like both has quite a high incidence of side effects.. although most people are fine. mom's freaking out at the thought of taking the vaccine.. putting thoughts of death rates into my head. a brief search on internet and now apart from death, got paralysis, bells palsy etc swimming in my head. i'm just wondering.. will i regret it if i don't take it? sigh... my mind's a blunder.. and i'm not getting younger. 26 will come all too soon.. :(
