The world now has a new Covid-19 vaccine in its arsenal, and at a fraction of the cost per dose.

Unlike the three vaccines approved in the U.S. – Pfizer and Moderna’s mRNA vaccines and Johnson & Johnson’s viral vector vaccine, which provide the body instructions on how to produce the spike protein – the new CORBEVAX vaccine delivers the spike protein to the body directly. Like those other approved COVID-19 mRNA vaccines, CORBEVAX also requires two doses.

But this vaccine can be produced at a much larger scale because appropriate manufacturing facilities are already available. Also key to global access is that CORBEVAX can be stored in a regular refrigerator. Therefore, it is possible to produce millions of doses rapidly and distribute them relatively easily.

Another major difference is that the CORBEVAX vaccine was developed with global vaccine access in mind. The goal was to make a low-cost, easy-to-produce-and-transport vaccine using a well-tested and safe method.
