While there is a lot of talk about a vaccine saving us, much of that talk isn’t supported by scientific evidence. Some key points:
- Most vaccine candidates are not designed to prevent the spread of coronavirus. The virus would still spread even if it causes less serious disease.
- There are mixed indications about whether or not a highly-effective vaccine for the coronavirus will emerge.
- There are now highly credible reports of re-infection cases. It is unlikely that herd immunity is possible. As far as a vaccine goes, it is likely that a vaccine would need to be frequently re-applied so that immunity does not fade.
