Volunteers wanted for research on mixing Covid vaccines

The Center of Excellence in Clinical Virology at Chulalongkorn University is looking for volunteers who have had two different types of Covid-19 vaccine, its chief announced on Thursday.

The institute has now opened registration for people who have received one each of the Sinovac and AstraZeneca jabs, Dr Yong Poovorawan, a top virologist leading the country’s Covid-19 situation, posted on Facebook.

Volunteers must wait at least a month after the second dose to be tested on their immune response. 

The announcement came after the doctor this week reported preliminary findings that mixing different brands can provoke a significantly stronger immune response compared with two doses of the same vaccine. (Read more here.) 

The Department of Disease Control ruled out mixing the two vaccines except in cases of a “severe allergic reaction.” Officials said there is not enough data to support mixing the vaccines as a standard measure to help cover supply shortages.

“The administration of vaccines would be much easier, faster, and efficient” if giving a different vaccine for the second dose was more widely accepted, Dr Yong said Sunday.

Those interested in volunteering for the study can register here.

The institute also put out a call for postdoctoral fellows or doctors specializing in virology and immunology to join their research programme on Covid-19. Interested researchers can call 02-256-4909, 02-256-4929, or email [email protected] or [email protected]
