New Delhi: Grieving parents of a young woman who died after receiving the AstraZeneca Covid-19 vaccine have criticized the NHS for not acting on safety warnings associated with the jab. The BBC reported that Marina Waldron, 21, passed away in March 2021 after suffering a brain hemorrhage. Her parents, Max and Liz Waldron, claim that A&E doctors were unaware of the vaccines emerging side effects, despite repeated warnings. Astrazenecas is the same vaccine that was rebranded and was being sold in India as Covishield.Multiple hospital visits before fatal collapseMarina, who had just begun her film career, visited the hospital three times with severe headaches before collapsing. She was given the AstraZeneca vaccine on March 11, 2021, and started experiencing symptoms on March 22. Despite mentioning the vaccine, she was repeatedly sent home with migraine tablets. She died on March 31 after suffering a heart attack and brain hemorrhage at Southmead Hospital in Bristol.Similar tragedy strikes another familyAnother family has voiced concerns after their son, Oli Akram Hoque, died from similar complications days after Marina. Both families are calling for lessons to be learned from these tragic incidents. Oli, 26, died in April 2021 after suffering from cerebral venous sinus thrombosis following his AstraZeneca vaccine. His sister claims doctors ignored his symptoms despite warnings being issued in Europe about the vaccines risks.Coroners verdict and calls for actionDuring Marinas inquest, the coroner concluded her death was due to vaccine-induced immune thrombocytopenia and thrombosis—a rare but recognized complication of the AstraZeneca jab. Although the coroner did not fault the NHS for not diagnosing the condition earlier, the Waldron family believes that increased awareness and quicker diagnostic measures could have saved their daughter.Government, AstraZeneca respondA spokesperson for the Department of Health and Social Care expressed sympathy for the families, reiterating that the health system acted quickly to respond to rare cases of complications. AstraZeneca defended the vaccine, highlighting that it had been widely recognized by governments for helping to end the pandemic, saving millions of lives.
