How close are we to having a covid-19 vaccine?

This Monday the Moderna company published preliminary data on its new vaccine against covid-19, ensuring that it is almost 95% effective.

The announcement comes days after Pfizer and the developers of the Russian Sputnik V vaccine released similar results.

Both Moderna and Pfizer develop RNA vaccines, a highly innovative and experimental approach that involves injecting part of the virus’s genetic code into the body.

Both companies indicated that they plan to apply for approval to use their vaccines in the coming weeks.
