Children ages 5-11 who received two doses of Pfizer’s mRNA COVID-19 vaccine had heightened levels of a type of antibody suggestive of an altered immune system response one year after vaccination, a new peer-reviewed study revealed.
Brian Hooker, Ph.D., chief scientific officer at Children’s Health Defense (CHD), told The Defender the study’s findings are very concerning because elevated IgG4 may be indicative of IgG4-related disease — a “multi-organ, fibro-inflammatory condition that usually involves the pancreas, kidneys or salivary glands but could involve any other organ.”
“Seventy to 80% of those with the disease have elevated IgG4,” Hooker said. “Although IgG4-related disease is treatable, the underlying autoimmune conditions are often chronic and will require a lifetime of treatment.”
