Some coronavirus survivors' immune systems may be producing antibodies that are attacking their bodies, the New York Times reports.

Why it matters: This may make severe coronavirus cases worse, and also may help explain why some patients suffer symptoms for months after being infected.

Details: These patients' immune systems have shifted from attacking the virus to attacking themselves — which is similar to what happens with diseases like lupus and rheumatoid arthritis.

  • The patients are producing "autoantibodies," which target genetic material from human cells rather than the virus.
  • The study has not been published in a scientific journal.
  • "Anytime you have that combination of inflammation and cell death, there is the potential for autoimmune disease and autoantibodies, more importantly, to emerge," Marion Pepper, an immunologist at the University of Washington, told NYT.

What's next: Doctors could use existing tests to find patients with autoantibodies, who may benefit from treatments used by lupus and rheumatoid arthritis patients.

Top scientists at the World Health Organization on Friday called for more detailed information on a coronavirus vaccine developed by AstraZeneca and the University of Oxford.

Why it matters: Oxford and AstraZeneca have said the vaccine was 90% effective in people who got a half dose followed by a full dose, and 62% effective in people who got two full doses. AstraZeneca has since acknowledged that the smaller dose received by some participants was the result of an error by a contractor, per the New York Times.

Why it matters: Coronavirus infections are still on the rise across much of the U.S. during a season of travel and holiday gatherings. Hospitals across the country, especially in rural areas, are still overwhelmed.
