The National Command and Operation Centre (NCOC) has revised the guidelines for the two-dose Chinese vaccines, increasing the gap between the doses to six weeks.
The two-dose SinoVac and Sinopharm vaccines were initially given with a four-week gap which has now been increased to six weeks.
Commenting on the development, Special Assistant to Prime Minister on Health Dr Faisal Sultan in an interview said that plenty of Sinovac doses were available in the country, while more were coming.
When asked whether the change is to overcome the shortage, the SAPM said, “It would provide some flexibility in timing. Will help in some situations.”
Meanwhile, it is reported that shortage of vaccines was the main reason behind enhancing the gap between the two doses and claimed: “that instead of decreasing efficacy, a delayed second dose could provide immunity.”
“The delayed second dose gives better immune response in general. China has successfully experienced that,” the official claimed.
Pakistan faced a shortage of vaccines last week and vaccination had to to be stopped in various cities till a fresh shipment of 1.5 million doses of Sinovac arrived Sunday.
