![]() ![]() Still, recent studies have confirmed these cases to be extremely rare and mostly benign.Īdditionally, an FDA document on recommending the vaccine for children ages 5-11 was taken out of context by these actors to justify their anti-vaccination stance. One of the many theories researchers are considering, according to the report, is the possibility that the spike protein, which is produced by the body after receiving the vaccine, might share similarities with ones found in the heart muscle, tricking the immune system into attacking the heart muscle. Yet these disinformation actors baselessly claimed the vaccine itself sends spike protein into a recipient’s “cell nuclei” and “suppresses DNA repair engine.” This narrative is misleading because “mRNA never enters the nucleus of the cell where our DNA (genetic material) is located, so it cannot change or influence our genes,” reads a CDC fact sheet.Ī recent Wall Street Journal report on scientists looking into how the mRNA-based vaccines could trigger myocarditis, pericarditis or other heart inflammation symptoms in a small number of recipients also drew attention from vaccine and pandemic skeptics. Natural News, InfoWars and other well-known disinformation actors intentionally misinterpreted a recently published paper on a potential mechanism of how full-length spike protein found on the coronavirus could diminish a person’s DNA repair system - especially in older people - and obstruct their adaptive immunity. ![]() Vaccine skeptics and deniers have weaponized this medical term to deter people from trusting Covid-19 vaccines, which have been proven effective and safe. Tutu Professor of Public Health and Human Rights and director of the Center for Public Health and Human Rights at the Johns Hopkins Bloomberg School of Public Health.Vaccine misinformation concerning the coronavirus spike protein has again picked up in recent days. It’s a new era for vaccine technology and production, and a testament to scientific progress and decades of research.Ĭhris Beyrer, MD, MPH ’91, is the Desmond M. Moderna is exploring applications of the technology to protect against HIV. Pfizer’s COVID-19 vaccine is the first mRNA product to achieve full FDA approval in the U.S.Īlready, vaccine manufacturers are developing mRNA vaccines to protect against other respiratory viruses such as the flu. With COVID, this technology got its moment and has proven to be extremely safe and effective. Thanks to decades of research and innovation, mRNA vaccine technology was ready. Some of those vaccines used traditional methods involving adenovirus as the spike protein delivery system-such as the Johnson & Johnson vector vaccine. Remember, the COVID-19 pandemic spurred manufacturers to develop dozens of potential vaccines against SARS-CoV-2 and brought tremendous increases in funding. The first mRNA vaccines using these fatty envelopes were developed against the deadly Ebola virus, but since that virus is only found in a limited number of African countries, it had no commercial development in the U.S. ![]() So, what happened once they figured out this technology? Once inside the cell, the mRNA message could be translated into proteins, like the spike protein of SARS-CoV-2, and the immune system would then be primed to recognize the foreign protein. The solution to this problem came from advances in nanotechnology: the development of fatty droplets (lipid nanoparticles) that wrapped the mRNA like a bubble, which allowed entry into the cells. The biggest challenge was that mRNA would be taken up by the body and quickly degraded before it could “deliver” its message-the RNA transcript-and be read into proteins in the cells. The early years of mRNA research were marked by a lot of enthusiasm for the technology but some difficult technical challenges that took a great deal of innovation to overcome. There’s a big gap between when the first mRNA flu vaccine was tested in mice in the 1990s and when the first mRNA vaccines for rabies were tested in humans in 2013. ![]()
