Found a 2017 article claiming the pneumonia vaccination would increase in cost

[Baitball Blogger]

just because. Maybe the cost of pneumonia vaccinations should come down in price, because that's something that everyone over 60 can do as a preventative. And the insurance companies won't pay for it until you reach 65.

The Ratcheting Price Of The Pneumococcal Vaccine: What Gives?

But the steady rise in prices for branded drugs contributes indirectly to rises in premiums, deductibles and government health spending, analysts say.

A full pediatric course of the vaccine typically involves four shots. In 2010, a single shot cost about $109, according to pricing archives kept by the CDC. It currently costs about $170, according to those archives. Next year, Pfizer says, a shot will cost almost $180.

“Pfizer and other drug companies are raising their prices because they can,” said Gerard Anderson, a health policy professor at Johns Hopkins University who studies drug pricing. “They have a patent, and they have a CDC recommendation, which is a double whammy — and a strong incentive for price increases.”

Under Section 2713 of the ACA, private health plans must provide coverage for a range of preventive services and may not impose cost-sharing (such as copayments, deductibles, or co-insurance) on patients receiving these services.3 These requirements apply to all private plans – including individual, small group, large group, and self-insured plans in which employers contract administrative services to a third party payer – with the exception of those plans that maintain “grandfathered” status.

II. ROUTINE IMMUNIZATIONS

Health plans must also provide coverage without cost-sharing for immunizations that are recommended and determined to be for routine use by the Advisory Committee on Immunization Practices (ACIP), a federal committee comprised of immunization experts that is convened by the Centers for Disease Control and Prevention. These guidelines require coverage for adults and children and include immunizations such as influenza, meningitis, tetanus, HPV, hepatitis A and B, measles, mumps, rubella, and varicella. An ACIP recommendation is considered to be issued on the date that it is adopted by the Director of the CDC.
