My trip to Argentina took a big turn when I got denied boarding the Emirates flight with final destination of Hyderabad. Apparently Hyderabad airport does not have a quarantine facility for travelers who do not have a valid Yellow fever vaccination certificate. It is interesting that Yellow fever is not even common in Argentina, which I got to know from the healthcare provider that gave me the vaccine and an international certificate proving it.
In any case, I am going to spend two more nights in Buenos Aires. I was able to catch a glimpse of Buenos Aires ATP tournament earlier.
