No new cases of a rare and severe blood clots following vaccination with AstraZeneca’s COVID shot have been reported in Britain in recent weeks after a decision to restrict its use in under-40s, British scientists said on Wednesday. Vaccine-induced immune thrombocytopenia and thrombosis (VITT) is a combination of blot clots and low platelet levels which has been labelled as a rare side effect of the viral vector COVID vaccines made by AstraZeneca and Johnson & Johnson. “We haven’t seen new cases for the last four weeks or so and this has been a tremendous relief,” she told reporters. Multiple clots were found in around one-third of cases, and almost all those hospitalised with the condition experienced it between five to 30 days after a first dose of AstraZeneca vaccine. J&J’s single-shot vaccine is not being rolled out in Britain.
