I dunno about Sinovac since I called to ask only about Sinopharm. The reason I called is also because MOH's messaging is very confusing. On first look, cannot use non-MRNA as booster but after I call, they confirmed can use.

I think they purposely do this so that people will take mRNA shots.

During the initial launch of Sinopharm, MOH does not approved the mixing of mRNA and nonRNA vaccines. Is only after sometime, then they 
approved.  However, private clinics said it is up to individuals to opt for Sinopharm as a booster if they wish to. It will still be considered as
fully vaccinated.  If the 4th booster jab must be a mRNA vaccine, I wud not want to opt for it.
