COVID Update October 2021

Vaccination does not prevent long-COVID (pre-print)

“[P]revious vaccination does not appear to be protective against several previously documented outcomes of COVID-19 such as long-COVID features, arrhythmia, joint pain, type 2 diabetes, liver disease, sleep disorders, and mood and anxiety disorders.” “However, the risk of several individual long-COVID features were significantly associated with prior vaccination (but did not survive correction for multiple comparisons): myalgia (HR 0.78, 95% CI 0.67-0.91), fatigue (HR 0.89, 95% CI 0.81-0.97), and pain (HR 0.90, 95% CI 0.81-0.99), with potentially additional protection after a second dose of the vaccine against abnormal breathing (HR 0.89, 95% CI 0.81-0.98) and cognitive symptoms (HR 0.87, 95% CI 0.76-0.99).”


“If we’re talking about a condition that’s going to affect 10-20% of those who survive COVID, we’re talking about 25 million people in the United States,” said Dr. Brian Block, the associate director of the medical ICU and the associate director of critical care ultrasound at UC San Francisco. “Whereas mortality has been in older adults, the group that seems most at risk to have the long-haul symptoms of COVID are younger, working age adults.” (Source)
