Thailand to mix Sinovac, AstraZeneca COVID-19 vaccine doses

Lahore, 12th July: Thailand will start mixing the Chinese Sinovac vaccine with America’s AstraZeneca COVID-19 vaccine in the first of its attempts. 

According to reports, Thailand will use the AstraZeneca vaccine as a second dose for those who had already received Sinovac’s shot as their first dose.

In order to increase protection against different variants of COVID-19 and specifically the Delta variant, the authorities announced their decision on Monday.

COVID-19: Can mixing vaccines boost immune response?

A new Thai study mixing the Chinese vaccine Sinovac with a Western-developed shot of AstraZeneca raised doubts about the long-term protection of the two-dose course of the Sinovac vaccine.

Health Minister Anutin Charnvirakul told reporters that this has been done to improve protection against the Delta variant and build a high level of immunity against the disease. He added that the second dose of AstraZeneca would come three or four weeks after the first Sinovac shot.

Is it safe and effective to mix and match COVID-19 vaccines?

As yet there have been no studies conducted on mixing Sinovac and AstraZeneca. However, some countries are now trying to mix and match different vaccines or giving a third booster shot after concerns that new and more contagious variants may escape approved vaccines.

The announcement came a day after 618 medical workers out of 677,348 personnel who received two doses of the Sinovac vaccine in Thailand contracted coronavirus from April to July.

Meanwhile, representatives from both Sinovac and AstraZeneca refused to make comments on the matter.
