The first mRNA vaccines using these fatty envelopes were developed against the deadly Ebola virus, but since that virus is only found in a limited number of African countries, it had no commercial development in the U.S.

THEN COVID-19 HIT … WHAT HAPPENED THEN?

Remember, the COVID-19 pandemic spurred manufacturers to develop dozens of potential vaccines against SARS-CoV-2 and brought tremendous increases in funding. Some of those vaccines used traditional methods involving adenovirus as the spike protein delivery system—such as the Johnson & Johnson vector vaccine.

Thanks to decades of research and innovation, mRNA vaccine technology was ready. With COVID, this technology got its moment and has proven to be extremely safe and effective. Pfizer’s COVID-19 vaccine is the first mRNA product to achieve full FDA approval in the U.S.
