Hidden Pneumonia Risk for 50+ and How to Stay Protected

Pneumococcal pneumonia is a serious threat to adults over 50 as aging immune systems weaken; about 150,000 Americans are hospitalized each year and roughly 1 in 20 die. Since symptoms can mimic a cold or flu, seek medical care if you don’t improve in 2–3 days or if you have severe signs like shortness of breath. Vaccines exist and are advised for those who are immunocompromised or over 65, but healthy 50+ adults should discuss vaccination with their doctor and focus on sleep, diet, and regular exercise to bolster immunity.

"Revitalizing Aging Immune Systems: Breakthroughs in Mouse Studies"

Researchers have discovered that an age-associated imbalance in hematopoietic stem cells (HSCs) is responsible for the decline in immune function in older individuals. By restoring a youthful balance of these cells using antibody injections, scientists were able to rejuvenate the immune systems of older mice, enabling them to better fend off viral attacks, borrowing an idea from cancer immunotherapy.
