Moderna is moving to the late stage trial of its COVID-influenza combination vaccine following positive results in preliminary trials, the company said, even as the brand’s COVID-19 vaccine raised multiple concerns about safety.
A combination vaccine is a mixture of individual vaccines. The mixing is done prior to administering it so that multiple vaccines can be delivered to the individual in a single injection. Moderna’s preliminary phase 1 and 2 trials of its mRNA-1083 combination vaccine against influenza and COVID-19 produced “positive interim results,” the company said in an Oct. 4 press release.
Moderna now plans to move on to the phase 3 late-stage trial of the vaccine.
The preliminary trials compared the mRNA-1083 combination vaccine against two influenza vaccines—Fluarix and Fluzone HD. Fluarix was administered to adults aged 50 to 64, while Fluzone HD is an enhanced influenza vaccine given to people aged 65 to 79.
For both groups, the combination vaccine was compared to the company’s Spikevax bivalent COVID-19 vaccine.
According to the drug manufacturer, the preliminary trials showed mRNA-1083 yielding antibody levels in blood similar to or greater than the two licensed influenza vaccines. It also yielded antibody levels similar to the firm’s COVID-19 vaccine.
The rate of adverse reactions for the mRNA-1083 was found to be “similar” to the Spikevax vaccine. A majority of adverse reactions were “grade 1 or 2 in severity.” Fewer than 4 percent of participants reported adverse reactions categorized to be grade 3 in severity.
“No new safety concerns were identified for mRNA-1083 compared to the standalone vaccines,” the company said.
The study published in the European Journal of Heart Failure analyzed the effect of Moderna’s mRNA-1273 COVID shot among health care workers in Switzerland.
It found that the vaccine was associated with “elevation of markers of myocardial injury” at the rate of about 1 in 35 individuals or 2.8 percent. In a generally healthy population, the rate would typically be about 1 percent, the researchers said.
Moderna’s Combo Vaccine Push
Moderna is planning to start the phase 3 trial of mRNA-1083 in adults aged 50 and above this year, aiming to get regulatory approval for the vaccine in 2025.“Combination vaccines offer an important opportunity to improve consumer and provider experience, increase compliance with public health recommendations, and deliver value for healthcare systems,” said Stephane Bancel, CEO of Moderna.
“We are excited to move combination respiratory vaccines into Phase 3 development and look forward to partnering with public health officials to address the significant seasonal threat posed to people by these viruses.”
Moderna estimates the U.S. influenza market to be 150 million doses annually, with the fall 2023 market estimated to be 50 million to 100 million doses.
The company anticipates that the market for COVID-19 vaccines will also “approach the influenza market” over time in the United States “given the burden of disease.”
COVID-19 Vaccine Dangers
While COVID-19 vaccines are being heavily promoted by governments and organizations across the world as critical to health care, numerous studies are pointing to a different picture, with one study blaming the vaccines for excess deaths.A Sept. 17 report published by Correlation calculated that there were 17 million COVID-19 vaccine-related deaths worldwide from 13.25 billion injections as of Sept. 2.
Researchers found that the overall risk of death due to COVID-19 vaccines is 1,000 times greater than previously reported in data from clinical trials, cause-of-death statistics from death certificates, and adverse event monitoring.
“COVID-19 vaccines and all of their progeny and future boosters are not safe for human use,” he said. Dr. McCullough stated that the spike protein from the COVID-19 vaccines is “proven” in 3,400 peer-reviewed manuscripts to cause four major domains of disease—cardiovascular, neurological disease, blood clots, and immunological abnormalities.
“Across Europe and across the United States, sports leagues were injecting young people who had no medical necessity, no clinical indication with these vaccines, and we have seen a montage of cardiac arrests in young individuals,” he said.
“I’m telling you as an expert cardiologist, these cardiac arrests are due to the COVID-19 vaccine until proven otherwise.”
