Thailand’s Department of Medical Sciences (DMS) has reported that combining Sinovac and AstraZeneca vaccines is highly efficacious in dealing with the Delta variant of COVID-19.
DMS Director-General Dr. Supakit Sirilak said that a Sinovac and AstraZeneca combination was the best, under the current circumstances, at speeding up immunity, citing lab test results from a study conducted in association with Siriraj Hospital.
He said blood samples from 125 participants, aged 18-60, who received a Sinovac shot and then an AstraZeneca jab, showed the quantitative level of immunity was an average of 716, compared with 117 among those who receive a full course of Sinovac and 207 for two AstraZeneca shots.
Dr. Supakit said the laboratory tests prove that combining Sinovac and AstraZeneca is appropriate. However, the test has not yet answered the question of efficacy duration, so further study is needed to determine when we should get the booster dose. (NNT)
