I've heard that herd immunity would require around 70% vaccine uptake. In the US, 77% of the population is 18 or older. Thus, your argument is really quite weak...even if what you describe were true, it would only affect about 7% of the population versus current age guidelines. However, what you are saying isn't true either. Nobody ever designated certain people to receive the vaccine and others to receive herd protection. We are simply rolling the vaccines out to more vulnerable cohorts first. Also, if this news is true it simply means that we need to vaccinate in the third world, where people cannot work from home and weaknesses in health infrastructure and education exacerbate transmission (and as a result, mutation). That may be good for pharmaceutical companies, or it may be a situation where the logistical costs are higher but companies are pressured to reduce pricing or release IP for public use.
