In the following year, SARS-CoV-2 triggered the Covid-19 pandemic.

As of March, 12 types of Covid-19 vaccines have been launched by 10 countries. The mRNA vaccine project was a by-product of 40 years of research, experience and knowhow from the SARS and MERS epidemics and a collaboration between bio startups and big pharma to fasten the mass production and marketing of the new vaccines.
