Another Study Confirms the Rise of IgG4 after the mRNA shots

Posted on by Jesse Santiano, M.D.

This article presents another study showing that the immune-tolerant IgG4 rises after COVID-29 mRNA injections. The International Society for Infectious Diseases published The Appearance of Anti-spike Receptor Binding Domain Immunoglobulin G4 Responses after Repetitive Immunization with Messenger RNA-based COVID-19 Vaccines in November 2023. The authors are from the Department of Microbiology & Immunology of the  Fukuoka…

mRNA COVID-19 Booster Shots Increase the Immunotolerant IgG4

Posted on by Jesse Santiano, M.D.

This article features the findings of a new preprint study: Third dose COVID-19 mRNA vaccine enhances IgG4 isotype switching and recognition of Omicron subvariants by memory B cells after mRNA but not adenovirus priming. It was published two days ago by BioRxiv. What is IgG4? Antibodies are one of the body’s first defenses against an…

The Devastating Effects of IgG4 after the mRNA COVID shots

Posted on by Jesse Santiano, M.D.

This article discusses the adverse health effects of the IgG4 that can develop after mRNA COVID-19 jabs. Ig stands for immunoglobulin, which is another name for antibodies. There are five major types of immunoglobulins. They are G, A, M, D, and E, designated as IgG, IgA, IgM, IgD, and IgE. They have different roles. IgAs are…

IgG4 is not increased in Long COVID Syndrome

Posted on by Jesse Santiano, M.D.

This article presents a new study showing that IgG4 is not elevated in Long COVID Syndrome.[1] Long COVID Syndrome The CDC defines Long COVID, Long Haul COVID, or Post COVID Syndrome as continuing COVID-19 symptoms after four weeks. It can last weeks, months, or even years after infection. Sometimes the symptoms can even go away…

13 Reasons Why COVID-19 Cases and Deaths May Increase Again

Posted on by Jesse Santiano, M.D.

Update Jan 12, 2023: I added another reason. SARS-CoV-2 variants of concern developed resistance to interferon as the pandemic progressed. Much new information came out recently about SARS-CoV-2, which causes COVID-19, the antivirals prescribed for it, and its “vaccines.” This article aims to increase awareness that SARS-CoV-2 reinfections can happen no matter if they have…

Three Studies Link High IgG4 to Severe COVID-19

Posted on by Jesse Santiano, M.D.

Previously, I published Pfizer mRNA shots Switch Antibodies to Non-Neutralizing IgG4. It featured research from Germany that showed that the IgG4 is produced by the memory B cells after two doses of Pfizer mRNA injection.  Immunoglobulin G4 is an antibody and is a subclass of IgG. IgGs are typically known to be active in fighting…

Pfizer mRNA shots Switch Antibodies to Non-Neutralizing IgG4

Posted on by Jesse Santiano, M.D.

A new peer-reviewed research showed that the Pfizer mRNA COVID shot could switch neutralizing antibodies to a non-inflammatory type, IgG4. The study may explain why vaccinated individuals have breakthrough infections and why Long COVID syndrome happens. Let’s start with a brief background that is relevant to the study Immunoglobulins Antibodies are also known as immunoglobulins….
