In this context, herd immunity describes a strategy proposed by a few countries (most notably by Prime Minister Boris Johnson of the UK), in which a country eliminates the disease by letting a large fraction of the population contract the disease and therefore become immune to it:
https://www.theguardian.com/world/2020/mar/13/herd-immunity-will-the-uks-coronavirus-strategy-workHerd immunity is a phrase normally used when large numbers of children have been vaccinated against a disease like measles, reducing the chances that others will get it. As a tactic in fighting a pandemic for which there is no vaccine, it is novel – and some say alarming.
It relies on people getting the disease – in this case Covid-19 – and becoming immune as a result. Generally it is thought that those who recover will be immune, at least for now, so they won’t get it twice.
But allowing the population to build up immunity in this way – rather than through widespread testing, tracking down the contacts of every case and isolating them, as many other countries in Asia and Europe have chosen to do – could increase the risk to the most vulnerable: older people with underlying health problems.
An analysis from Imperial College London suggests that such a strategy, even with the best efforts to mitigate the effects, such as quarantining the elderly and other susceptible populations would overwhelm hospitals with a surge of critically ill people eight times larger than the health system in the UK could deal with.
Sure, herd immunity would make a country safer, but achieving herd immunity (in the absence of a vaccine) requires getting 60-70% of the population infected, which would be very dangerous and deadly.
