Tested on rhesus macaques. Worked well for 44% of them.

It's a positive step, but still a fair way off for humans.

It doesn't need to be 100% effective in humans, it just needs to slow transmission enough such that the rate of incidence declines in the direction of eradication.

  • It will have the opposite effect, if people who get the vaccine start behaving as though they are 100% protected (which, many people will).

    • This is called moral hazard, and people love to worry about it. Usually though (the relevant example here is PrEP, or birth control) it's fine and enables people to live their lives with fewer risks to their, and others, wellbeing
