some medical expert kept saying on radio 4 last night we needed people to be affected to build up long term resistance to corona virus, does that mean we can expect more variations of this flu in years to come, worse more dangerous versions and we need to have some kind of tolerance
SARS and MERS were apparently somewhat similar coronaviruses too. So even if you'd be immune to this, the next version of the virus is probably just different enough. But apparently herd immunity is the way to get through this pandemia indeed.
Samuli-
MERS has a case fatality rate of >40% and an R0 of ~0.4
SARS has a case fatality rate of 10% and an R0 of ~2.2At an estimated R0 of 1.8 an CSR of 1% this is somewhere near Cholera on this graph.

NO ITS NOT

For Herd Immunity to be effective you need at least 90%-95% of people to have immunity. Exposure to other coronaviruses will do nothing for you against this specific new coronavirus.
Without a vaccine then the only way to have immunity will be to have had this specific virus and survived. Given it has a case fatality rate of ~1% you'll only get to 90% herd immunity levels in the population once a good 700,000 people have died.
