From the Guidelines

mRNA vaccines do not cause cell gene mutation or autoimmune disease. These vaccines work by delivering messenger RNA that instructs cells to produce a specific viral protein (like the SARS-CoV-2 spike protein), triggering an immune response without altering the cell's DNA. The mRNA never enters the cell nucleus where DNA is stored, making genetic mutation impossible. Additionally, the mRNA degrades naturally within days after vaccination. While some people experience temporary side effects as the immune system responds to the vaccine, extensive clinical trials and real-world data from hundreds of millions of administered doses have not shown any link between mRNA vaccines and the development of autoimmune conditions, as supported by recent studies 1.

The technology has been studied for decades before COVID-19, with a strong safety profile. The benefits of vaccination in preventing serious illness and death from infectious diseases far outweigh the theoretical risks, which have not materialized in scientific observation. For example, a study published in 2022 found that mRNA vaccines are safe and effective in patients with cancer, and that the efficacy of mRNA vaccines in patients with solid tumors and hematological malignancies is 83% and 72%, respectively 1. Another study found that mRNA vaccines are safe to administer to patients with inflammatory bowel diseases, and that the influence of IBD medications on the decision and timing for SARS-CoV-2 vaccination should be considered 1.

Anyone with specific concerns about vaccines should consult with their healthcare provider for personalized advice. It is essential to note that the safety profile of mRNA vaccines in special populations, such as patients with rheumatologic and autoimmune diseases, has been extensively studied, and the benefits of vaccination outweigh the risks, as recommended by the American College of Rheumatology 1.

Some key considerations for vaccination in special populations include:

  • Patients with rheumatologic and autoimmune diseases should receive mRNA vaccines, unless contraindicated, and the decision to vaccinate should be made individually, considering the underlying disease and treatment 1.
  • Patients with cancer should receive mRNA vaccines, and the timing of vaccination should be carefully considered, taking into account the type of cancer and treatment 1.
  • Patients with inflammatory bowel diseases should receive mRNA vaccines, and the influence of IBD medications on the decision and timing for SARS-CoV-2 vaccination should be considered 1.

In summary, mRNA vaccines are safe and effective in preventing serious illness and death from infectious diseases, and do not cause cell gene mutation or autoimmune disease. The benefits of vaccination outweigh the theoretical risks, which have not materialized in scientific observation.

From the Research

mRNA Vaccines and Autoimmune Disease

  • The study 2 found that mRNA vaccines decouple SARS-CoV-2 immunity from autoantibody responses observed during acute COVID-19, suggesting that mRNA vaccines do not promote the development of autoantibodies.
  • Another study 3 found that the BNT162b2 mRNA COVID-19 vaccine and booster are associated with better COVID-19 outcomes in patients with autoimmune rheumatic diseases, with no increased risk of autoimmune reactions.

mRNA Vaccines and Cell Gene Mutation

  • There is no direct evidence in the provided studies to suggest that mRNA vaccines cause cell gene mutation.
  • However, the study 4 mentions that mRNA vaccines have the potential for low-cost manufacture and safe administration, implying that they are designed to be safe and non-toxic.

Safety and Efficacy of mRNA Vaccines

  • The study 5 found that mRNA vaccines have shown more than 90% protective efficacy against symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection alongside tolerable safety profiles in pivotal phase III clinical trials.
  • The study 6 reviews the recent development of mRNA vaccines and therapies, highlighting their potential for conquering fast-spreading infections and other clinical applications, with a focus on safety and efficacy.

mRNA Vaccines in Patients with Autoimmune Diseases

  • The study 2 found that autoimmune patients on certain modes of immunosuppression had impaired virus-specific antibody responses post-vaccination, but autoantibody dynamics were remarkably stable in all vaccinated patients.
  • The study 3 found that patients with autoimmune rheumatic diseases who received the BNT162b2 mRNA COVID-19 vaccine and booster had better COVID-19 outcomes, with no increased risk of autoimmune reactions.
