Questions About the Bivalent COVID-19 Booster Vaccine


In September, The New England Journal of Medicine (NEJM) published a new Moderna-sponsored study on the efficacy of the initial bivalent vaccine targeting BA.1 in comparison to the original monovalent booster.

The primary focus of the study—antibody titers—shows seemingly positive results. In all groups (Omicron being of greatest interest), the bivalent shot created higher antibody levels than the monovalent booster shot.

Based on this finding, the authors conclude, “The bivalent omicron-containing vaccine mRNA-1273.214 elicited neutralizing antibody responses against omicron that were superior to those with mRNA-1273.”

Not so fast. There are a number of serious concerns from the study.

First, there was no statistically significant difference in incidence of COVID-19 cases in either arm. In fact, the bivalent group had a higher number of COVID-19 cases compared to the original booster. As Dr. Tracy Beth Hoeg noted, in the group without natural immunity, the bivalent arm had three times as many cases as the monovalent arm.

The demonstrated superior antibody levels and seeming ineffectiveness against infection may appear contradictory, but the two metrics are loosely connected. There’s no clear understanding of what levels of antibodies are needed to confer SARS-CoV-2 immunity.

Even though the nebulous endpoint of increased antibody titers was used in the initial Moderna and Pfizer trials, both the Food and Drug Administration and Centers for Disease Control and Prevention explicitly recommend against testing antibodies to determine immunity post-vaccination. Moreover, Pfizer has conceded there is “no established correlate of protection” between antibody levels and immunity. Needless to say, reams of real-world data also show the unreliability of broadly deploying vaccines based on antibody studies.

More alarming than unknown bivalent effectiveness is the mounting evidence of “immune imprinting”—a concern initially flagged by the European Union regulators. As vaccine proponent Eric Topol highlights in his unusually sober-minded analysis of the bivalent shots, there is a “disturbing trend of much lower antibody induction vs Omicron compared to that mounted against the ancestral (original) strain.”

Topol writes, “[I]t’s certainly a concern that there are not much higher levels of neutralizing antibodies, with this metric considered as a surrogate marker for protection vs severe Covid.”

Another major problem of the study was its assessment of “safety”—one of its “primary objectives.” No “evident safety concerns” were found, but again, the sample size of the study was in the hundreds. The most documented serious adverse event—heart inflammation—occurs, at most, at a rate of 1 in 1,800 in young males. The bivalent arm of the study contained a mere 437 participants (of which 179 were men).

However, that doesn’t seem to be the case. While a few are starting to wake up, the most influential vaccine promoters continue to plunge into collective psychosis. President Joe Biden appears to have accidentally declared an end to the pandemic, but unvaccinated foreigners are still barred from entering, and, most egregiously, a number of elite universities have announced mandatory bivalent vaccines for all undergraduate students.

Let us hope the evidence against mass administration of mRNA vaccines becomes incontrovertible to the point that vaccine zealots don’t have a modicum of defense.
