If he's already had it for 6 days, then you have already been exposed. You will either get the chicken pox yourself in about another week or may get lucky and not get it at all. Only time will tell. I had my child vaccinated for it here in Qatar, but at my insistance they had to order it and ship it in for me---took about 6 months. This was a couple of years ago now, however, so many they keep it in stock now. Dial 180 (directory assistance) and ask for the number for Abu Hamour vaccination center. Call them and ask them if you can get the innoculation.
