Sharjah 24 – Reuters: Novavax Inc said on Monday, June 14 that its new COVID-19 vaccine was more than 90% effective against a variety of coronavirus variants.
The company says its vaccine is most effective against the original coronavirus strain, as well as the Alpha strain that was first detected in the UK.
The vaccine is a more conventional type of mixture than those currently available.
Novavax does not use mRNA, unlike mRNA vaccines like that of Pfizer and Moderna, which contain a piece of genetic code, called RNA, that prompts the body to create an immune response against the virus.
Novavax differs from this in that it uses the traditional approach of injecting purified pieces of the virus to spur an immune response more directly.
It contains an actual version of the virus' spike protein that has been treated so it cannot cause disease, but can still trigger the immune system.
The body can then make antibodies against the spike proteins that cover the coronavirus and which enable the virus to penetrate human cell membranes.
