Vaxzevria showed no increased incidence of thrombosis with thrombocytopenia after second dose for COVID 19.- AstraZeneca
Rates of the very rare clotting disorder, thrombosis with thrombocytopenia syndrome (TTS), following a second dose of Vaxzevria are comparable to the background rate in an unvaccinated population. The data, published in The Lancet demonstrated the estimated rate of TTS following a second dose of Vaxzevria was 2.3 per million vaccinees, comparable to the background rate observed in an unvaccinated population. It was 8.1 per million vaccinees after the first dose. The rate after the second dose is comparable to background rates observed in unvaccinated populations.
