Isn't it only if an effective vaccine is created?
For instance, what if it becomes like the flu? Vaccine exists, but flu still does the rounds.
Additionally, with some reinfections happening, what does that mean? Why didn't the people who had covid-19 a first time have immunity?
- mantap 7y agoIt is expected to be more stable than influenza. So regional eradication is conceivable in the long term and it's likely to eventually become one of those diseases that is limited to poorer/harder to reach parts of the world. But that is certainly years away. For now we all have zero immunity. The relapses are a bit of a mystery but it's not uncommon with viruses e.g. various herpes viruses.
- ehsankia 7y agoThe problem with flu isn't tha the vaccine itself isn't effective, it actually protects you from the strains it's designed to just fine, it's just that the influenza virus is unstable and mutates, leading to new versions that you no longer are protected against. So yes, it depends on how stable COVID-19 is as mentioned below.
- jfoster 7y agoAware of this. It does depend on that, and so will the effectiveness of any vaccine.
