If you had bet that Katy Perry and Russell Brand would never last or that the Cleveland Browns would NOT field a Super Bowl team in 2012 — well, then your crystal ball is working as well as the YOU Docs’ did when eight years ago we said that everyone 50 or older should get a pneumonia vaccine.

The Food and Drug Administration now agrees: A vaccine, called Prevnar 13, that was for kids ages 6 months to 5 years old, is now available for people 50-plus. It attacks 13 strains of the lung-congesting and inflammation-causing bug and may pack a bigger punch than older vaccines (including Pneumovax) that used to be doled out only to those folks who were 65 or older.

For the more than 300,000 people over 50 who are projected to be hospitalized with pneumonia this year, that’s very good news. But the vaccine’s power doesn’t stop there.

YOU Docs are on record saying that for folks 50 and up, the vaccine called Pneumovax reduces inflammation that damages blood vessels and makes your brain foggy and your thinking fuzzy. Dr. Oz got this high-caliber shot when he tuned 50; so did Young Dr. Mike!

Does Prevnar do the same? Probably, but frankly, preventing pneumonia and possibly reducing your risk of heart attack by 50 percent is more than enough reason for us — and you — to go ahead and get vaccinated.

Medicare and most insurance companies cover it. If yours doesn’t, SWITCH; they are demonstrating just how much they do not care about you.
