Same with HIV...still no vaccine regardless to the billions of dollars thrown at it.
Hopefully, other companies are doing the other side of the coin...treatments to keep people from developing any illnesses that can kill. Just as important, the vaccine or treatment is available for free and doesn't cost +100 dollars to get.
Typically, its normal to see early positive results by the researchers but the optimism soon evaporates within months when they see that the vaccine and/or treatment are producing worst results in comparison to those that are infected but did not take a vaccine / treatment.

HIV and cancer are diseases that do not go away on their own while COVID19 does, so it is not a good comparison.
Also, now COVID19 is a global pandemic that is easily transmissible and kills an individual in a short period of time. Majority of the pharma/biotech firm are currently concentrating their effort to resolve this. Compare that to the number of firms working to research cancer or HIV cures.
