COVID-19 vaccine (Astrazeneca) and thromboembolic events with concurrent low platelet counts
I am writing to you following the CMO letter HSS(MD) 28/2021 (dated 8th April 2021) to outline the operational procedures which should be followed for any patient reporting symptoms suggestive of a blood clot more than 4 days and within 28 days from receiving a dose of Astrazeneca vaccine. The following symptoms suggest the need for urgent medical investigation:
new onset of severe headache, which is getting worse and does not respond to simple painkillers
an unusual headache which seems worse when lying down or bending over, or may be accompanied by blurred vision, nausea and vomiting, difficulty with speech, weakness, drowsiness or seizures
new unexplained pinprick bruising or bleeding
shortness of breath, chest pain, leg swelling
persistent abdominal pain
