As the world start to reopen with more and more people getting vaccinated for COVID-19, there actually looms a possibility for one more wave of COVID-19. Worse, this wave might even worse than those seen so far in the western world, at least, where there’s been lots of resources devoted to controlling the pandemic. This is because while the vaccine is highly effective at 95%, for the best case scenario, that still leaves one in twenty people at risk in what might eventually be a bit of a “free for all” scenario for spread with people being a lot closer, without masks, in large group, etc. Five percent of any population is a lot of people! Do the math for your city, state, province, country, whatever.
