BENGALURU: AstraZeneca's Covid-19 shot did not increase the instances of rare blood clots with low platelets in people after the second dose, a study showed on Wednesday, potentially easing some worries over the vaccine's side-effects.

Data published in the Lancet medical journal found that the estimated rate of thrombosis with thrombocytopenia syndrome (TTS) after the second dose of the vaccine was 2.3 per million in those inoculated, comparable to the typical rate seen in those who have not been vaccinated, AstraZeneca said https://www.astrazeneca.com/content/astraz/media-centre/press-releases/2021/vaxzevria-showed-no-increased-incidence-of-thrombosis-with-thrombocytopenia-after-second-dose.html.
