Local New research explores antibody response following complete Sinopharm vaccination

A latest study Dr. Chandima Jeewandara has found that among persons who have been administered the Sinopharm vaccine, the antibody response declined in all age groups, especially in those above 60 years, while the T cell responses persisted.

The research, which has not been peer-reviewed yet, investigated the persistence of immune responses in Sri Lankans who were administered the Sinophram vaccine.

Dr. Jeewandara is the Director of Operations and Clinical Services at the Allergy, Immunology, and Cell Biology Unit of the Sri Jayewardenepura University.

His findings show that the presence of the COVID-19 specific total antibodies as well as T cells were detected in the individuals sampled after 12 weeks from the second dose of the vaccine.

It has been concluded that antibody responses declined in all age groups, especially in those above the age of 60 years, while T cell responses persisted.

The effect of immunity waning on hospitalization and severe disease should be assessed by long-term efficacy studies.
