After my mitral valve repair surgery in August 2015, Kaiser gave me the Pneumovax 23 immunization before I was discharged from the hospital. Apparently this was the standard of care, at least at that time.
Kaiser does follow Medicare and CDC recommendations for its Standard of Care. Unfortunately, Medicare and the CDC are not always transparent in why they make reccomendations. Sometimes the committees that they use are stacked with MDs from Universities and Big Pharma companies and these MDs reflect the biases of their employers. This stacking is not necessarily deliberate. Universities and Big Pharma can afford to give their staff professional development time for these activities. Self employed MDs usually cannot afford the time off. One of my uncles who was a self employed engineer said that for him, vacations were a time of maximum stress.
Kaiser does not pay for professional development time for their doctors (At least my regional Kaiser does not). Thus, I suspect that their doctors do not get to serve on committees either.
The economist, Milton Friedman, said that regulatory bodies always develop advisory committees for helping develop rules and research. Initially, these committees are always stacked with activists. Over time, they evolve to be stacked with representatives of those being regulated (Hospitals, Medical Schools, Manufacturers of drugs and Manufacturers of Medical Equipment) because those organizations "have the most skin in the game".
One has to do one's own research at PubMed ( (the National Library of Medicine (NLM) of the National Institute of Health (NIH) ) to try to figure out whether the different guidelines are suitable for you. Unfortunately, Kaiser does not do that research. Sometimes, the answer is that while they are suitable for the general population (say of Mitral Valve Prolapse patients) they are not suitable for you as an individual.
As a starting point for Pubmed -
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4778694/which is a 2016 Jan-Feb article on "A Review of Pneumococcal Vaccines: Current Polysaccharide Vaccine Recommendations and Future Protein Antigens"
On the right side of the page, PubMed gives related articles and articles which cite that article. Caution - you can get lost forever in this forest of data. It is as bad as the Internet. : - )
