Pneumonia vaccine once in a lifetime or more often

Our local vaccination clinic advises a pneumonia shot for everybody once every five years. They also charge the earth for it. I read on the internet that the vaccine is just once in a lifetime, except for people who have serious health problems. Which is correct? Thank you.

Here's some good reasons NOT to get this vaccination. Don't be misled by the medical profession. References are shown below

Flawed Clinical Trials Did Not Prove Safety: Wyeth Lederle and Kaiser Permanente compared one experimental vaccine (pneumococcal) against another (meningococcal)1, which seriously compromised the scientific validity of the trial. Children in groups who got the pneumococcal vaccine suffered more seizures, irritability, high fevers and other reactions. There were 12 deaths in the Prevnar group, including 5 Sudden Infant Death Syndrome (SIDS) deaths. [Since the vaccine was licensed in 2000, there have been 3,243 Prevnar-related adverse events reported to the federal government (VAERS), including 476 serious events and 79 deaths.]3

路 No Long Term Studies: There were no long term studies to evaluate whether Prevnar vaccine given alone or in combination with other vaccines is associated with chronic illness or disability, such as the development of diabetes, asthma, seizure disorders, learning disabilities, ADHD, or autism.

路 Vaccine Components Not Thoroughly Evaluated: Each 0.5ml dose of Prevnar contains 0.125 mg. of aluminum, a metal that is neurotoxic. The vaccine manufacturer states that "Prevnar has not been evaluated for any carcinogenic or mutagenic potential, or impairment of fertility." 4,1
