This is speculation. I might as well speculate that a vaccine that does not prevent infection or spread, but also puts selective pressure on the virus to escape vaccine immunity, is likely to lead to a vaccine-escape mutation when administered to a large population. This mutation then poses a risk to those who would need the vaccine that has now become ineffective.
The fact that we currently see mutations coming out populations that aren't vaccinated is a number's game. Most of the world population is not vaccinated. Vaccinating the last 30% in developed nations will not change that.
- logicalmonster 5y agoSpeaking of speculation, I would strongly speculate that the vaccine will greatly increase the spread of illness. If the vaccines dull the symptoms to the point that vaccinated people don't readily know that they're sick, then vaccinated people aren't going to be staying home when they're carriers. In contrast, it seems far likelier that unvaccinated people will feel ill and stay home.
- munk-a 5y agoThat is a very real danger with constant medication and vaccination - however the observed effect has been the opposite. The lowered impact of sickness leads to shorter periods of contagiousness which has lowered the spread rate. The vaccine is effectively lowering the r-value. A large proportion of unvaccinated persons is strongly correlated with higher case rates.
- incrudible 5y ago> the observed effect has been the opposite Did you really observe that? There's many highly vaccinated countries that have seen spikes with extremely high r-values.
