From what we know, there are no long lasting effects after you get infected. From all we know until now, you get immunized after you win over your first infection. And since the birth deffects comes from the virus going through the placenta barrier and attacking the fetus brain, you can have healthy babies after you get immunized.
The problem is a bit more complex. With a mass influx of people comming to Brazil we could potentially spread the virus to other countries, with this we could see a massive increase of birth effects, like microcephaly, all over the world due to the increased range of action due to the new populations of vectors.
