Early research goes back to 1989, first human trials were around 2000, Moderna started development in 2010, and the first human trials against infectious disease was 2013, plus several other viruses in the mid 2010s.
I haven't found decent information on what those trials find after a year, 3 years, 5 years, 10+ years... I'm sure a lot of it is a matter of figuring out why a vaccine adversely effects a small portion of people, and seeing those effects right away.... versus people suddenly dropping dead 5 years later or developing some other disease that can be linked to the vaccine, etc.
It's something I've been curious about with previous research and trials, if it's just being super diligent or if they routinely learn new things years later.
