The Sinovac Booster Dose Can Activate Cellular Immunity Against Omicron Variant

According to preliminary findings from research undertaken by the Pontifical Catholic University of Chile (UC), a booster dose of the Covid-19 Sinovac vaccine may activate cellular immunity against the Omicron variant in individuals who previously received two doses of the same vaccine.

The research, coordinated by Millennium Institute on Immunology and Immunotherapy director Prof Dr Alexis M. Kalergis, sought to determine if the Sinovac vaccination booster dose-induced immunity was capable of recognising the Omicron variant.

In a statement made by Pharmaniaga on Saturday (Jan 1), Dr Alexis said that individuals who received the Covid-19 Sinovac vaccine booster dose had T-cell levels that were stimulated similarly as the original strain against the Omicron variant.

This shows that the vaccine contains antigens that are found in the Omicron variant. The results show that when T-lymphocytes come in contact with the Omicron variant, they are able to produce gamma interferon, which is capable of killing the dangerous virus," he said.

Meanwhile, Dr Susan Bueno, UC’s Academic and Scientific Director for the CoronaVac Scientific-Clinical Study in Chile, said that partial identification of these variants most likely contributed to the vaccine’s efficacy in the population, despite the variants’ prevalence in Chile.

Population data shows that the Covid-19 Sinovac vaccine has worked well so far to control the variants that have emerged," she said.

Additionally, the announcement said that researchers in Chile were undertaking a study on the antibody response to the novel variant in collaboration with the Catholic University, the University of Chile, the La Jolla Institute for Immunology in California (USA), and Sinovac in China.

The new Omicron (B.1.1.529) Covid-19 variant of concern (VoC), identified in South Africa and also detected in Europe and Asia, has sparked global concern due to the high number of mutations and reports that it may spread even faster and evade antibodies associated with previous virus infection or vaccination.

Sinovac Covid-19 booster doses have been licensed by Malaysia’s Drug Control Authority and are now accessible in select private healthcare centres.
