No, but it might wipe out more people from industrialised countries.
There was a recent study on immunization take up rates and trust in immunisation around the world (I don't have the link to hand but IIRC it was released about a year ago) which showed that the single greatest belief in and adoption of immunisation was occurring in the developing world. The developed nations were actually experiencing a decline in trust and take up rates.
Why? There's a very simple answer to this. People in developing nations have seen the consequences of Measles, Polio, Chicken Pox et al. They've got relatives or friends who have died from these diseases and they see first hand that immunisations are saving lives.
In developed nations, immunisation has been around for several generations and as such, people in these nations haven't seen what these diseases can do. For all intents and purposes, the diseases don't exist. So, when a pseudo-scientist tells them that vaccinations can cause autism or some other scare mongering falsehood, they have a skewed risk analysis insofar as they weigh this potential risk of the vaccination against what they see as an almost zero risk of infection without vaccination, because in their experience it never happens.
In some developed countries, faith in vaccinations has fallen to as little as 60%. In the developing world is consistently in the 90% range.
Bottom line is that if you could make such a virus, it's likely to backfire and wipe out a different group to that which you're targeting.
