The grieving wife of a leading Florida doctor has told DailyMail.com how her ‘perfect’ husband died from a mystery blood disorder - just days after getting the Pfizer Covid-19 vaccine. Heidi Neckelmann says obstetrician Gregory Michael, 56 - her ‘best friend’ and partner of 28 years – was active, healthy and had no pre-existing conditions before getting the jab on December 18. However he died from a stroke Sunday morning after suddenly developing a rare autoimmune illness that causes the body to destroy its own platelets, the tiny fragments that help blood to clot. Distraught Heidi, 58, thinks the groundbreaking Pfizer-BioNtech vaccine may have somehow been the trigger. ‘In my mind his death was 100 percent linked to the vaccine. There is no other explanation,’ she told DailyMail.com, fighting back tears. ‘He was in very good health. He didn’t smoke, he drank alcohol once in a while but only socially. He worked out, we had kayaks, he was a deep sea fisherman. ‘They tested him for everything you can imagine afterwards, even cancer, and there was absolutely nothing else wrong with him.’ Pfizer told DailyMail.com Wednesday that it was aware of Dr. Michael's ‘highly unusual’ death and was investigating further. However a spokesman cautioned: ‘We don’t believe at this time that there is any direct connection to the vaccine.’ Dad-of-one Gregory suffered no immediate reaction to the injection but three days later he was taking a shower and noticed petechiae - spots of red that indicate bleeding beneath the skin - on his feet and hands. When he checked himself into Mount Sinai Medical Center in Miami Beach, the hospital where he works and had the groundbreaking vaccine, medics discovered he was suffering from an acute lack of platelets. ‘All the blood results came back normal except for the platelets which came back as zero,’ Heidi said. ‘At first they thought it must be a mistake. So they did the test again and this time did a manual count which is supposed to be more accurate. This time it showed just one platelet. ‘He felt 100 percent, he was normal, energetic, happy. But they said you cannot go home, this is incredibly dangerous, you could suffer a brain bleed and die.’ Normally doctors would expect a range of between 150,000 to 450,000 platelets per microliter of blood. Their primary function is to help the blood clot and prevent bleeding. Heidi says doctors tried frantically to reverse what they diagnosed as an acute immune disorder known as ITP - idiopathic thrombocytopenic purpura. In people with ITP, also known as severe thrombocytopenia, the immune system mistakes platelets for foreign objects and instructs the spleen to destroy them. It can be acute or chronic, lasting six months or more, striking on its own or in conjunction with other autoimmune conditions, certain cancers or during pregnancy. Kids can get ITP after a viral infection such as the flu or mumps, while in adults, triggers can include HIV, hepatitis or H. pylori, a type of bacteria that causes stomach ulcers. Gregory’s wife insists, however, that had
