India approves first DNA Covid vaccine
My very limited understanding tells me that the human body is a very complex system not fully understood.<p>I only have engineering analogies, but deploying bad software in a complex distributed system can appear fine until latent effects are discovered literally years later (e.g. all data in a specific column for a subset of users was overwritten for records within 6 months in 2008).<p>My understanding with some debilitating, fatal conditions are that the causes are not well known.<p>Fundamentally, it seems that most science is a result of abductive, deductive reasoning etc but ultimately, tinkering and observation i.e. if you don&#x27;t analyse something over 10 years, you don&#x27;t know its effect over 10 years.<p>By using a variety of different vaccines all over the world the expression of humanity is that we are spreading the risk among various vaccine types or contracting COVID itself.<p>So for a mostly self-interested individual in a rural area with a low chance of catching COVID, would it follow that the safest (but maybe selfish) bet is to wait many years?<p>Or is my premise or conclusion flawed, especially because I missing prerequisite knowledge?
