I’m skeptical of the RNA vaccines too, but those aren’t valid comparisons. Flu vaccine has a lower efficacy because the virus can shuffle genetic information much easier than COVID and the lead time on developing the flu vaccine means they don’t always get the specific strain right. And “cancer” isn’t a single disease with a single cause - the mechanism of breast cancers are different than prostate cancer are different than leukemia, etc. It’s not possible to make a single vaccine for “cancer”.
Yes and no. The symptoms of “common cold” can be potentially caused by hundreds of different viruses - mostly rhinoviruses, although a certain portion is coronaviruses. Like cancer, there are so many different causative agents of common cold that you can’t make a one-hit vaccine to take out all of them. COVID-19 is an individual coronavirus strain, so you can make a vaccine that targets it specifically.
Hell, there’s already a black market for negative test results.
