Scientists suspect COVID-19 may be subtly damaging immune systems, akin to measles, by depleting T-cells and causing lasting inflammation.

Despite political resistance to this alarming idea, evidence suggests SARS-CoV-2 could be reprogramming our immunity on a global scale, making us more susceptible to everything.
