Why don't we have a vaccine for SARS? MERS? HIV? These viruses have been around longer than SARS-CoV-2. A mini-thread to provide some perspective and even a little dose of optimism. We are not in the same situation here. 1/7

It’s been a long time since I’ve read my virology and epidemiology textbooks and I am certainly no expert, but if the drug companies can be convinced to keep working on a SARS-CoV-2 vaccine, the chances we can develop one is about 95% from what I can tell.
If we do fail to develop one, the most likely reason for that is not that it’s technologically impossible but that it’s not profitable.
