P.S. : If it turns out the Moderna corp's vaccine that can be kept in a regular freezer is confirmed 94.5% effective, we do have a shot at eliminating that virus with vax campaings.

At a 95% effectiveness and ~75% vaccination coverage, it's almost a win in the box.

The Pfizer vaccine ( 90%+ effective preliminary results ) needing -70C? I don't see ot happening in the third world. It's already a logistical difficulty in rich countries.

Since I'm not at risk I am not getting a vaccine without a rock'-solid plan for effective total elimination. Vaccinate at-risk people : problem solved.

Low-risk people are at less risk from this than the regular flu, and it might be better for kids to grow-up getting periodic exposure to it so their immune system develops a good response to it over the long term, if we cannot eliminate it totally.
