This is likely a serious answer to a sarcastic question, but there are academic article databases that rank research on things like where they were published, how many times they were cited in a positive way in other articles. The quality of your research and positive cites can be a big factor in gaining tenure if you are at a research institution like a university. There's no Rivals/ESPN/MaxPreps/247 Sports style top ranking, but you generally know who is in the top tier based off of academic article rankings, grant money gained, and posts at important labs or research centers. It's not obvious to the average person, but if you are in the field you know who the top dogs are.Where are the vaccine expert rankings published and what are their criteria? Very interested to learn more about that process.
