Herd Immunity, is it possible?

The idea of society achieving herd immunity from Covid-19 is a topic of intense interest. Herd immunity implies group protection to the disease. This happens because enough people get the illness and/or vaccines. The leading theory is that 60-80% of society needs to be infected/vaccinated to achieve herd. Full community immunity may be unachievable, instead covid will likely become endemic. This means that it’s a permanent fixture in our lives. The good news is endemic infections are usually less severe. Many even hypothesize that eventually covid could resemble the common cold since most of society will have had covid or the vaccine multiple times allowing for greater immunity to the illness.
