VACCINE MAKER: Another vaccine maker using the mRNA platform is Moderna, a Massachusetts-based biotech company, now also in advanced Phase-3 trials of its COVID-19 vaccine. Though yet unproven, mRNA vaccines had been under development since the 1990s. It essentially "trains" the human body to produce the antibodies necessary to fight the real virus when a person gets infected. As a vaccine development platform, mRNA is a relatively quick and inexpensive way to mass produce vaccines, and is theorically safer too, as it doesn't use live or killed versions of the virus used in traditional vaccine platforms. mRNA-based vaccines could make a huge impact due to their shorter manufacturing times and potential efficacy.
