There isn’t any knowledge to recommend persons are at elevated danger of a uncommon, however critical, blood clot situation after receiving a second dose of J&J’s vaccine, in keeping with J&J govt Dr. Macaya Douoguih.

She introduced knowledge from the U.Okay. on second doses of AstraZeneca’s vaccine, which makes use of an identical platform to J&J’s. The information reveals the speed of vaccine-induced immune thrombotic thrombocytopenia, or VITT, after a second dose was much less frequent than the primary.

“Though the vectors usually are not completely the identical, the info could present some perception into potential danger,” Douoguih stated.
