FDA adds sec­ond warn­ing to J&J's Covid-19 vac­cine on da­ta link­ing it to rare nerve con­di­tion

The J&J Covid-19 vac­cine has been linked to a sec­ond rare but se­ri­ous side ef­fect.

The FDA is­sued a warn­ing Mon­day af­ter­noon that there are da­ta “con­nect­ing the shot to an in­creased risk” of Guil­lain-Bar­ré syn­drome, a rare con­di­tion where the body’s im­mune sys­tem at­tacks its nerves. The FDA said that there were 100 pre­lim­i­nary re­ports of the syn­drome out of the 12.5 mil­lion peo­ple who re­ceived the vac­cine. No such re­la­tion­ship was seen be­tween the Mod­er­na or Pfiz­er-BioN­Tech vac­cines and the au­toim­mune con­di­tion.
