Preliminary Results: Moderna Covid-19 Vaccine Is 94.5% Effective

05:57

Last Monday the world got some good news: an early review of the data showed that Pfizer’s Covid-19 vaccine was “more than 90% effective” in preventing the disease. The results pointed to other vaccines also being highly effective against the virus and this morning comes this news: Early Data Show Moderna’s Coronavirus Vaccine Is 94.5% Effective.

The drugmaker Moderna announced on Monday that its coronavirus vaccine was 94.5 percent effective, based on an early look at the results from its large, continuing study.

Researchers said the results were better than they had dared to imagine. But the vaccine will not be widely available for months, probably not until spring.

Despite the delivery timeline, this is such good news.

The companies’ products open the door to an entirely new way of creating vaccines — and creating them fast. Both use a synthetic version of coronavirus genetic material, called messenger RNA or mRNA, to program a person’s cells to churn out many copies of a fragment of the virus. That fragment sets off alarms in the immune system and stimulates it to attack, should the real virus try to invade. Although a number of vaccines using this technology are in development for other infections and cancers, none have yet been approved or marketed.

“The fact that two different vaccines made by two different companies with two different kinds of structures, in a new messenger RNA concept, both worked so effectively confirms the concept once and for all that this is a viable strategy not only for Covid but for future infectious disease threats,” said Dr. Barry R. Bloom, a professor of public health at Harvard.

Natalie E. Dean, a biostatistician at the University of Florida, said an important finding was that the vaccine appeared to prevent severe disease. Pfizer did not release information about disease severity when reporting its results.

Researchers say the positive results from Pfizer and Moderna bode well for other vaccines, because all of the candidates being tested aim at the same target - the so-called spike protein on the coronavirus that it uses to invade human cells.

It’s only a few more months — please please do what you can to stay safe and keep others safe (especially medical workers) until these vaccines can be rolled out.
