Jokes aside, there's a long way to go before this line of research leads to a product anywhere near as effective as vaccination.
Quoting from the OP:
- "CBD is quite hydrophobic and forms large micellar structures that are trapped and broken down in the liver, thereby limiting the amount of drug available to other tissues after oral administration."
- "other means of CBD administration such as vaping and smoking raise concerns about potential lung damage"
- "The purity of CBD and, in particular, the composition of the materials labelled as CBD are also important, especially in light of our findings suggesting that other cannabinoids such as THC might act to counter CBD antiviral efficacy"
- "The necessary human in vivo concentration and optimal route and formulation remain to be defined"
