Research has shown that COVID-19 mRNA vaccines reduce bacteria belonging to the genus Bifidobacteria, a common and beneficial gut bacteria. Vaccination against COVID is also linked to reduced gut biodiversity.
The works of the gastroenterologist Dra. Sabine Hazan, CEO of ProgenaBiome, a microbiome genomics research laboratory, found that after vaccination against COVID-19, people’s bifidobacteria levels can decrease as much as 90 percent. Some of their unpublished data found that levels of bifidobacteria are negligible in vaccinated people.
Bifidobacteria are among the first microbes to colonize a baby’s gastrointestinal tract as it passes through the mother’s birth canal. They are believed to exert positive effects on the health of their host.
Bifidobacteria interact with the immune system and their presence is linked to improved immunity against pathogens and cancer.
Previous works of Dr. Hazan on hospitalized patients with COVID-19 proved that patients who had severe COVID-19 tended to have no or low levels of bifidobacteria, while those with higher reserves of bifidobacteria tended to develop asymptomatic infection.
In her research, she came across a pair of siblings enrolled in clinical trials of the COVID-19 vaccine.
“One sibling received a placebo and another received the vaccine. The only brother who received the vaccine was injured… and does not have Bifidobacteria bacteria. His brother, who got the placebo and didn’t get hurt, has this bifidobacterium,” he told The Epoch Times.
The importance of bifidobacteria
The loss of Bifidobacteria was discovered by comparing the diversity of the microbiome both before and after vaccination. In general, the loss is transient, while it can persist for more than nine months in more extreme cases.
There are also rare cases where the patient’s population of bifidobacteria increases. Dr. Hazan talked about one patient’s population of bifidobacteria that doubled a month after vaccination. However, six to nine months after vaccination, the patient’s bifidobacteria count had dropped to zero.
Dr. Hazan said it is not known why some people’s bifidobacteria levels rise after vaccination.
Bifidobacteria are a common probiotic and it is well established that humans can consume them to improve gut health. In fact, products containing Bifidobacteria account for trillions of dollars in market share of the probiotics market.
The absence of bifidobacteria microbes is linked to chronic diseases, such as diabetes, cancer and autoimmune diseases. Some studies have shown that administration of probiotic bifidobacteria can help improve diabetes conditions and help fight cancer.
Loss of other microbes after vaccination
Some patients may have other missing microbiomes after vaccination, and trying to trace what microbes the patient might have had before vaccination involves difficult forensic work, Dr. Hazan said.
A study Hong Kong researchers found that administration of the COVID-19 mRNA vaccine was directly linked to reduced gut biodiversity, resulting in a loss of at least 10 different microbes.
Although some vaccinated people saw an increase in certain bacteria, the vaccination reduced the overall diversity of the microbiome.
The authors also noted that the risks of common adverse reactions such as fever, headaches, pain at the injection sites, etc., may also be related to the bacteria in the gut. For example, patients with high bifidobacteria tend to be less inclined to develop adverse reactions to the vaccine.
A gut microbiome with low biodiversity is associated with poor health and aging. After birth, babies develop a very diverse gut microbiome. As they age, they lose this diversity as they develop diseases, take antibiotics and drugs, eat unhealthily, sleep less, and so on.
Bifidobacteria can make up up to 95 percent of a baby’s gut microbiome during infancy. It then declines and stabilizes at less than 10% in adulthood.
However, Dr. Hazan has seen cases of babies breastfed by vaccinated mothers who do not have bifidobacteria. The long-term consequences of this are unknown, especially since bifidobacteria are involved in building a person’s immune system.
Growing awareness of the importance of the gut microbiome in health has led some parents to freeze their baby’s first stool for a future fecal transplant, internist Dr. Yusuf Saleeby told The Epoch Times. As the baby grows and its microbiome is depleted, the fecal sample can be transplanted to correct the composition of the gut microbiome.
“If the child gets sick and there is dysbiosis, the parents can go back to the company.. and re-inoculate those microbes into the baby, to try to get back what the baby should have had,” he explained.
