Earlier this year, My sister and elderly mother had to go to hospital, both exactly three weeks to the day after the first booster - both with dangerously low white blood cell counts - Doctors baffled - after three days in hospital for my mother and a day / night for ny sister both released to GP care tio monitor the issue with paracetamol. During 9 months period of having the two primary doses mother developed rapid decline and diagnosed with alzheimers. No idea must be old age. Fck that noise, myself and my two young sons are pure blood.
