On April 27, a news that Pfizer’s mRNA vaccine may cause autoimmune hepatitis caused concern.
The Paper reported that a study recently published in the Journal of Hepatology showed that a new coronavirus mRNA vaccine jointly developed by Pfizer and BioNTech may cause a rare form of autoimmune hepatitis. The Journal of Hepatology is the number one academic journal in the field of gastroenterology and liver, with an impact factor of 25.083 in 2021.
It is not the first time that the novel coronavirus mRNA vaccine causes hepatitis. In April 2021, a similar situation was reported for the Moderna vaccine.
But the information that Pfizer’s vaccine causes hepatitis was widely spread because public opinion linked it to the recent emergence of “hepatitis in children of unknown etiology” in many countries.
On April 23, the World Health Organization reported that nearly 200 cases of childhood hepatitis of unknown etiology have been found in more than ten countries including the United Kingdom, Spain, and the United States, and at least one The patient died. Researchers have initially detected new coronaviruses and adenoviruses in related cases, but the roles of these two viruses in the pathogenesis are not clear.
Prior to the unexplained hepatitis incident, on April 11, CFOs Frank Damerio and David Merrill of Pfizer and Moderna, the world’s leading mRNA vaccine manufacturers On the same day, he announced his resignation, all of which were “at retirement age”.
Pfizer’s Damerio, who joined the company in 2007 and led Pfizer’s acquisitions of companies including Wyeth Pharmaceuticals, reportedly plans to retire in 2021; Moderna’s Merrill is 87 , just joined Moderna for two years.
The scientific community generally agrees that mRNA vaccines are not associated with “hepatitis of unknown etiology”. The British Health Security Agency has stated that none of the children with hepatitis has been vaccinated against the new crown;
