COVID-19 mRNA vaccines may weaken immune response to other infections, raising concerns about immune deficiency.

Study Raises Concerns ​Over Pfizer’s COVID-19 Vaccine and Immune Deficiencies

A ⁣recent study on the immune effects ⁤of Pfizer’s COVID-19 mRNA vaccine has scientists raising concerns over vaccine-acquired ‍immune deficiencies.

Vaccine-acquired immune‌ deficiency syndrome (VAIDS) is ⁢a new term coined by researchers and ‌health practitioners‍ since the ​COVID-19 vaccine rollout. Some experts believe ‌the COVID-19 vaccines may ​impair or‍ suppress immune responses.

While the study ​does not use the term VAIDS, the researchers found a general decrease‌ in⁢ cytokine ‌and chemokine responses to bacteria,⁤ fungi, and‍ non-COVID viruses in⁢ children after COVID-19 vaccination.

“Our​ findings suggest SARS-CoV-2 mRNA vaccination could ‌alter the⁢ immune response ‌to ⁢other pathogens, which cause‌ both ⁢vaccine-preventable and non-vaccine-preventable diseases,” the authors of the paper published⁤ in Frontiers in Immunology wrote.

This ​is particularly relevant⁣ in children as they​ have extensive exposure to microbes and receive multiple vaccines as part of routine ⁢childhood vaccination schedules.

The‍ researchers took blood⁢ samples⁢ of 29 children, both before and​ after​ two ‍Pfizer mRNA doses. They found that blood samples ⁤post-vaccination‍ had a lower cytokine response to non-COVID pathogens compared ⁤to pre-vaccination.⁢ This reduced immune response was particularly persistent for non-COVID viruses.

Immune responses to COVID-19 proteins remained high after vaccination.

Professor⁣ Retsef Levi, specializing in risk management and health systems at ⁤MIT,⁢ posted on X (formerly known as Twitter) that the study “adds to cumulative evidence suggesting adverse immune alteration” by ⁢COVID-19 vaccination.

Marc Veldhoen, an immunologist, challenged the study’s findings.

In an X⁤ thread, Mr. Veldhoen highlighted⁤ flaws⁣ in⁣ the study, including the lack of controls and⁣ larger sample size.

Accumulation of Studies ⁤Suggesting Decreased Immunity After Vaccination

The study is one of‍ many suggesting ‌declined immune ‌response after COVID-19 vaccination.

A preprint study in 16 adults inoculated with the Pfizer mRNA vaccines had⁢ similar ‍findings⁢ of a reduced innate immune response in participants exposed to pathogenic fungi. The same paper also found ⁢long-term changes in innate immune cells.

The Epoch ‍Times reported ⁢on a January‌ study out of Germany ⁣that showed multiple mRNA vaccinations‍ induce a “class switch”⁣ in ‌the type of antibodies ​formed against the spike protein and other COVID-19 proteins.

Boosted individuals have increased IgG subclass 4 ⁣(IgG4) antibodies, which are less effective than other subtypes of IgG antibodies.

“The development of more IgG4 than usual is⁢ unhealthy and riskier for people if they encounter the real‍ virus later, as COVID-
