Moderna claims 94% efficacy for COVID-19 vaccine, will ask FDA for emergency use authorization today

Moderna is developing three new mRNA-based vaccines for seasonal flu, HIV and Nipah virus

Moderna, the biotech firm behind one of many two mRNA-based vaccines at the moment being rolled out globally to stem the tide of COVID-19, has introduced that it’s going to purse improvement applications round three new vaccine candidates in 2021. These embrace potential vaccines for HIV, seasonal flu and the Nipah virus. Moderna’s improvement and scientific trial of its COVID-19 vaccine is among the many quickest in historical past, and to this point its outcomes have been very promising, buoying hopes for the efficacy of different preventative remedies being generated utilizing this know-how which is new to human scientific use.

An mRNA vaccine differs from typical, historic vaccines as a result of it includes offering an individual with only a set of directions on learn how to construct particular proteins that can set off a physique’s pure defenses. The mRNA directions, that are momentary and don’t have an effect on an individual’s precise DNA, merely immediate the physique’s cells to supply proteins that mirror these utilized by a virus to connect to and infect cells.
