True for the US, sure, because of its healthcare capacity and financial resources (rapid development and deployment of potent mRNA vaccines). Peru has likely lost near 1% of its entire population due to Covid (200k deaths, 32m population, guaranteed vast undercount due to local conditions). They'll recover from that no doubt, and the population will ultimately acquire widespread immunity with or without vaccines (which would bring down the rate of deaths), however it's definitely not a tiny percentage of the population to lose so quickly.
It's going to be an incredible rolling challenge to handle the bottom ~3-4 billion people getting Covid vaccinations every year to prevent millions of people from dying annually. And that's assuming the mass propogation of Covid to all humans and a lot of animals isn't going to eventually unleash super deadly strains.
The Guardian had an interview last week or the week before with someone who appeared to know what they were talking about. They made the point that there are dozens of known respiratory viruses already, and that although they constantly mutate and pose new challenges, we have not seen them ever mutate into "super deadly" strains.
I take some comfort from that (even though it is clearly not a sure thing).
The problem with COVID-19 has never been the risk it poses for you as an individual, but the public health aspects. It is highly infectious; some number of cases require hospitalization; if too many people require that at the same time, the public health implications are substantial, much broader than COVID-19 itself, and potentially lethal.
Ergo, we have a civic responsibility to take steps to reduce the chance of this happening, and the simplest way to do that is vaccination and masks.
