mRNA vaccines for COVID-19 

The use of messenger RNA (mRNA) in medical interventions has been researched for the last 20 years, including in vaccines hoping to fight diseases such as cancer, rabies, Ebola and Zika fever, which means the research technology was ready to be applied to this new disease, COVID-19. With the authorisation of two mRNA vaccines for emergency use to fight COVID-19 and more vaccine candidates in development, we can build protection against the virus in our communities if enough people are vaccinated.
