Gunmen opened fire on a World Health Organization (WHO) vehicle in Pakistan's southern seaport of Karachi on July 17.
Officials said the shooting wounded a foreign doctor working on a polio immunization campaign and a local driver.
The shooting happened in the impoverished Soharb Ghoth neighborhood.
WHO says the two men are in stable condition in a private hospital.
The Geneva-based agency said there is no evidence to suggest that this was a targeted attack against polio eradication efforts or the WHO.
Pakistan is in the second day of a three-day campaign to vaccinate children under 5.
Taliban militants in northern Pakistan have banned the vaccination, saying it can't go forward until the United States stops drone strikes in Pakistan.
