Prevnar (pneumococcal vaccine) 13 vaccine has diphtheria proteins in it. Does Prevnar (pneumococcal vaccine) 13 vaccine protect against pneumococcus and diphtheria? Thank-you!
No: The diphtheria proteins used for PCV-13 (Prevnar) are not antigenic for diphtheria. That means they are not recognized by the body to produce an immune response. They just help carry the pneumococcal proteins into the appropriate cells to create the immune response for the pneumococcal bacteria. ...Read more
Protection wears off: The protection provided by a tetanus shot usually provides ample levels of circulating antibody protection for up to ten years. After that point it fades & the person may develop tetanus if exposed.

It reduces the risk of anal cancer in boys and girls as well as the risk of cervical cancer in girls. Hopefully it will reduce some other hpv related cancers. The Gardasil hpv also reduces sexually transmitted warts by 90%. ...Read more
No: Our instincts suggest your immune system may react more vigorously and give you a more tender arm but recent studies suggest that is not the case.
