Experimental CoViD-19 vaccines

 Scientists don't always know what they're doing - especially when they are experimenting and anything could happen! 

Take the new messenger RNA vaccine (or mRNA for short), developed in record time for the novel 2019 coronavirus disease (CoViD-19 for short). Normally vaccines go through years and years of testing to make sure they are truly safe, but these have been pushed through "because this is an emergency". Regarding CoViD-19, vaccines, and natural immunity vs vaccine-induced immunity:

What if.. 

1. Immunity induced from covid vaccines is short-lived? 
2. It isn't as good or long-lasting as natural immunity? 
3. They only work on strains that are already 'old hat'? 
4. They facilitate (or even cause) the virus to mutate into even deadlier strains? 
5. They interfere with our ability to develop natural immunity? 
6. And from that they make those jabbed dependent on vaccines? 
7. They cause hidden long-term detrimental effects on health? 

Possible answers:

1. We know that already. There's already talk of 'boosters'. 
2. Recovered cases are showing stronger resistance to reinfection. 
3. They are suspected of being only half effective on Delta already. 
4. Quite possible - even likely. 
5. We already know that the body is fooled by induced antibodies that everything is going ok and thinks it doesn't need to produce more of its own accord. 
6. Only the test of time will reveal the answer to that. 
7. Only the test of time will reveal the answer to that. 

The problem is two-fold. We risk death from CoViD-19 by not being vaccinated because some of us are genetically prone to respiratory failure, and although the majority (around 80%) only suffer mild symptoms or none at all, it's hit and miss whether we are going to die from it. 

By remaining unvaccinated we are taking that gamble. Yet the rewards for taking a chance are potentially huge - like any gamble. If we contract CoViD-19 and get over it with few side effects we will have strong antibodies that may even protect us from new mutant strains. Not only are they better than artificially induced ones, but they will last longer, possibly even a lifetime. 

Yet there is also a gamble in getting vaccinated. It's quite possible that in a hundred years the only people left on the planet will be descendants of unvaccinated people with strong immunity who have survived the pandemic – and all those vaccinated over and over again have ended up with no immunity and no defences, thus falling victim to mutant strains. 

I say this, not as a scientist, not as a conspiracy theorist, not even as a sci-fi fan - but as a pragmatist who wonders about the possible dangers of scientific experimentation on the majority of the world's population all at once. This may turn out to be the scariest movie ever!
