Gene-based vaccination–quo vadis?
Sucharit Bhakdi MD, Karina Reiss PhD, and Michael Palmer MD
Introduction of any foreign substance into the body can never be entirely devoid of risks, however, so the prime question to be addressed is whether the benefit can be expected to outweigh the risks. Therefore, the pathogen must be dangerous—an infection with it is associated with a high morbidity and mortality rate, and
vaccination will generate robust immunological protection against severe disease.
I usually Google your vaunted "experts", only to find they have No Credentials in the subjects you claim they are experts in. SOoo Done with that, it will be just more of the same old same old, IMO you would quote Yosemite Sam if he happened to make a remark that fitted your bizarro "thinking"
'Professor Sucharit Bhakdi MD is a retired Professor Emeritus of Medical Microbiology and Immunology, Former Chair, Institute of Medical Microbiology and Hygiene, Johannes Gutenberg University of Mainz.

Karina Reiss Ph.D.
Karina Reiss was born in Germany and studied biology at the University of Kiel where she received her PhD in 2001. She became assistant professor in 2006 and associate professor in 2008 at the University of Kiel. She has published over sixty articles in the fields of cell biology, biochemistry, inflammation, and infection, which have gained international recognition and received prestigious honors and awards.
'Dr. Michael Palmer is an Associate Professor of Biochemistry at the University of Waterloo (Canada) teaching Pharmacology and Toxicology. Dr. Palmer's advanced research in biochemistry focuses on the interaction of peptides and proteins with biological membranes. One current area of interest is the action mode of lipopeptide antibiotic daptomycin, as well as the mechanism of bacterial resistance to it.'
Bizarro thought....
'These requisites were fulfilled in the historic successes of vaccine development against smallpox, tetanus, diphtheria and poliomyelitis. The euphoria created by these scientific milestones caused one decisive fact to be overlooked, however. In all four cases, the agents were transported to their destination in the bloodstream.
It is essential to realize that this is the exception and not the rule. Most viral pathogens cause self-limiting infections of the respiratory or the gastrointestinal tract. Severe damage to internal organs caused by their spread via the bloodstream occurs infrequently, and infections are generally not associated with high death rates. Because of their ubiquity, a high level of background immunity to such viruses is already present in the general population. For these simple reasons, a genuine need for development of vaccines against most viral pathogens does not exist.'
'Immunity to respiratory viruses: systemic versus mucosal immunity
We now turn to an important fact regarding the protection of the respiratory tract against infections: it is mediated by cells of the immune system which reside within and beneath our respiratory mucous membranes, and these cells function quite independently from those immune cells which protect our internal organs.
A key aspect of this functional separation between mucosal and systemic immunity concerns the nature of antibodies produced by plasma cells located directly beneath the mucous membranes. These antibodies—secretory immunoglobulin A (sIgA)—are secreted across the mucous membranes to their surface. They are thus on site to meet airborne viruses, and they may be able to prevent them from binding and infecting the cells within those mucous membranes. The same mode of protection pertains to the digestive tract as well.
In contrast, IgG and circulating IgA are the main antibodies found in the bloodstream. They cannot prevent the entry of viruses into the cells that line the airways or the gut, and they may at best counteract their spread if they gain entry to the circulation. Crucially, vaccines that are injected into the muscle—i.e., the interior of the body—will only induce IgG and circulating IgA, but not secretory IgA. The antibodies induced by such vaccines therefore cannot and will not effectively protect the cells of the respiratory tract against infection by airborne viruses. This realization is neither contentious nor new. As long as 30 years ago, McGhee et al. concluded:
It is surprising that despite our current level of understanding of the common mucosal immune system, almost all current vaccines are given to humans by the parenteral route [i.e. by injection]. Systemic immunization is essentially ineffective for induction of mucosal immune responses. Since the majority of infectious microorganisms are encountered through mucosal surface areas, it is logical to consider the induction of protective antibodies and T cell responses in mucosal tissues.'
The failure of intramuscular injection to induce secretory IgA has been confirmed in a study on Middle East Respiratory Syndrome (MERS). Like COVID-19, this disease is caused by a coronavirus, and the experimental vaccine used in the study was gene-based, like all of the major vaccines currently deployed against COVID-19. More recently, another study has shown that the mRNA COVID-vaccines also do not stimulate substantive production of secretory IgA. For this simple reason, one cannot expect that vaccination will inhibit airway infection. Indeed, the utter failure of the vaccines to prevent SARS-CoV-2 infection is today solidly documented.
It is general knowledge that secretory IgA antibodies (sIgA) are produced in response to naturally occurring airway infections. The mucous membranes of healthy individuals are consequently coated with antibodies directed against common respiratory viruses. However, the capacity of these antibodies to prevent infections is limited. The outcome of an encounter with a virus is not “black or white”—numbers are all-important. A wall of protective antibodies may ward off a small-scale attack, but it will be breached at higher viral loads. This is why infections with airborne viruses occur repeatedly throughout life, a fact that will not even be altered by the use of intranasal vaccines in order to stimulate sIgA-production, even though intranasal vaccine application does induce stronger mucosal immune responses than does intramuscular injection.
