Dr Sultan added that the prime minister has isolated himself at home after the test report.

"PM Imran Khan has tested positive for Covid-19 and is self-isolating at home"

Khan had received the first jab of the COVID-19 vaccine two days earlier. He was yet to take the 2nd dose. According to the experts, the vaccine is only effective after both doses are administered.

Federal Minister for Planning and Development Asad Umar took to Twitter to address concerns raised about the efficiency of the vaccine after the premier tested positive. In his tweet, Asad said:

"May Allah protect him and give him shifa. Some people questioning the efficacy of vaccination since he was vaccinated Thursday evening. The symptoms take a few days before manifesting. Hence, it is certain that PM had been infected PRIOR to vaccination. So please do vaccinate."

Ministry of National Health Services also issued a statement on Twitter to clarify the ambiguity:

"Prime Minister Imran Khan was not fully vaccinated when he contracted the virus. He only got the 1st dose and merely 2 days ago which is too soon for ANY vaccine to become effective. Anti-bodies develop 2-3 weeks after the 2nd dose of 2-dose COVID vaccines. #VaccinesWork"
