This warning came from Dr. William Makis, a Canadian physician with a triple specialization in radiology, oncology and immunology and the author of over 100 peer-reviewed medical articles. Makis provided two cases of babies who passed away due to being breastfed by mothers fully vaccinated against COVID-19.

One case involved a 36-year-old mother from New Mexico, who wrote about how her eight-week-old baby died on July 2021.

"He became very sick with a high fever on June 21, about two weeks after I got the first Pfizer vaccine," she wrote. "He was treated for two weeks with IV antibiotics for a supposed bacterial infection, however they never found any bacteria."

"After the 14-day course of antibiotics, he was home for one week, but exhibited strange symptoms," she continued, noting how her child had a swollen eyelid, strange rashes and was regularly vomiting.

"I took him back to the hospital on July 15, where he presented with what they called an atypical Kawasaki disease. He passed away shortly thereafter from clots in his severely inflamed arteries," she concluded.

Makis presented another case, that of a five-month old baby who died on March 20, 2021, just three days after the infant's mother received her second dose of Pfizer's mRNA vaccine.
