Drawing on a national database of over four million people, researchers in New Zealand have found a strong association between Pfizer’s mRNA Covid shot and kidney injuries.
In the three weeks after a mRNA jab, the risk of acute kidney injury rose 60 percent, the researchers found. They reported almost 1,800 extra cases – the equivalent of over 100,000 extra cases of kidney injury in the United States.
The finding was posted as a “preprint” in The Lancet’s database on Friday, Jan. 20. It is the third signal from a large government-managed database linking the Pfizer’s mRNA shots to serious side effects in only the last six weeks.
The authors did not define “acute kidney injury,” a term that can cover anything from relatively benign changes on laboratory tests to a serious loss of renal function.
Still, the finding is yet another signal of the potential cardiovascular risks of the mRNAs. The kidneys essentially function as filters for the blood, and renal injuries often result from reduced blood flow to the kidneys.
The researchers also found elevated rates of heart inflammation, blood clots, and platelet damage in the weeks after one or both of the shots. In all, they found a statistical link between the Pfizer shot for four of the 12 conditions they examined.
The finding is particularly strong because the researchers did not have to depend on voluntary reporting. Instead, they compared New Zealand’s national health records to its national database of people over five who received the vaccine. Just over 4 million New Zealanders, including 95 percent of adults and teenagers, received the shots, providing a large pool to track.
The researchers then compared the number of “adverse events” they found to historical background rates.
In addition, New Zealand had relatively low rates of Covid for most of the period during which people received the Pfizer jabs, so Covid itself cannot be blamed for the excess injuries.
