Pfizer Says Trials Show COVID Vaccine Is 90% Effective, But Questions Remain on Safety of Novel Tech
“Because there’s never been a licensed mRNA vaccine before, we really don’t know what injuries are going to look like.” — Mary Holland
Pfizer announced Monday preliminary analysis of its COVID-19 vaccine trials indicates the vaccine will be more than 90% effective. The news sent stocks soaring and had the media all but doing cartwheels.
But the New York Times pointed out that Pfizer’s data — delivered in a news release, not a peer-reviewed medical journal — “is not conclusive evidence that the vaccine is safe and effective, and the initial finding of more than 90 percent efficacy could change as the trial goes on.”
Jesse Goodman, professor of medicine and infectious diseases at Georgetown University, told the Times, “We need to see the actual data, and we’re going to need longer-term results.”
Fast Company reported on the development by reminding readers that the Pfizer vaccine, if approved, will be the first to use “an as-yet-unproven technology platform that relies on something called messenger RNA, usually shortened to mRNA.”
Moderna is also working on an mRNA COVID vaccine. In May, Children’s Health Defense reported that clinical trials for Moderna’s vaccine had a 20% “serious injury rate” in its high-dose group. Moderna told the New York Times this week it expects interim findings from its study this month.
Commenting on Pfizer’s latest vaccine news, Mary Holland, vice chair and general counsel for Children’s Health Defense, said:
“New vaccine technology will likely mean new kinds of vaccine injuries. Because there’s never been a licensed mRNA vaccine before, we really don’t know what injuries are going to look like. In that the vaccines were developed so quickly, with such short clinical trials, the long-term injuries are a complete unknown.”
What exactly is mRNA technology? Fast Company describes it this way:
“Like other vaccines, mRNA vaccines work by training the immune system to recognize a threat like a virus and begin producing antibodies to protect itself. But while traditional vaccines often use inactivated doses of the organisms that cause disease, mRNA vaccines are designed to make the body produce those proteins itself. Messenger RNA — a molecule that contains instructions for cells to make DNA — is injected into cells. In the case of COVID-19, mRNA vaccines provide instructions for cells to start producing the ‘spike’ protein of the new coronavirus, the protein that helps the virus get into cells. On its own, the spike protein isn’t harmful. But it triggers the immune system to begin a defensive response. As Bill Gates, who has supported companies like Moderna and BioNTech through the Gates Foundation, has described it, ‘you essentially turn your body into its own manufacturing unit.’”
Holland and others are concerned that the combination of novel technology, fast-track approvals and widespread panic that could trigger new vaccine mandates may lead to unprecedented types and numbers of injuries […]
