approval, said Vice Director of Clinical
Research Unit of Pasteur Institute of Ho Chi Minh city Nguyen Trong Toan.

According to Dr. Toan, the was first researched by the National
Health Research Institute (NHRI) of Taiwan (China), then continued to be
transferred and developed through clinical trials.

From 2019 to 2021, the third clinical trial was conducted on
3,049 children aged two months to six years in Vietnam and Taiwan, with the number
of accounting for 80%.

In Vietnam, children in six districts of the Mekong Delta
provinces of Tien Giang and Dong Thap were selected for clinical trials because
these localities recorded high rates of HFMD.

The trial in Vietnam had to take longer than scheduled due
to the impact of COVID-19, Toan said.

Findings show that the protective efficacy of the vaccine in
helping defend against the EV71 strain – the most dangerous virus strain that
causes HFMD with a high risk of death, is 96.8%. During the study period, there
were no cases of HFMD recorded among the children who received the vaccine.

Researchers have not detected any post-vaccination anaphylaxis.

Based on the clinical trial results, the production unit
submitted a dossier to the Ministry of Health for approval, Toan said.
