Hyderabad: Senior citizens who have taken both doses of Covisheild vaccine in six to eight weeks are worried if they have immunity against Covid-19 after the revision of duration by the Union health ministry to 12 to 16 weeks.
The new guideline has got many of them calling their doctors to check whether they have the required immunity or would require one more dose of the vaccine. Many of them are worried whether they are protected as they ventured out to super markets, bazaars and neighbourhoods for shopping and walks. It is only the last few days of lockdown that they have not moved out but were socially active after vaccination.
Dr Rahul Agarwal, general physician and internal medicine specialist at Medicover Hospitals says, "In a pandemic caused by novel and unknown viruses, there will be changes in vaccination protocol after real world evidence. It is inconvenient but we have to bear it. Senior citizens, healthcare and frontline workers have received both doses of vaccine. Those working closely with Covid-19 patients have shown reasonably good immunity after two doses. Senior citizens must not worry. They must follow safety protocols despite vaccination as that is important and not give up."
Wearing masks, sanitisation and social distancing must be followed even if both doses are administered, urged the doctors....
