Yes... can.

No, cannot. Same as Sinovac. MOH only recognises mRNA.

[Updated 13 Jan] Should persons who had completed the Sinovac-CoronaVac vaccine three dose primary series receive a booster?  What booster should they receive?

Persons who had received two or more doses of the Sinovac-CoronaVac* COVID-19 vaccines as part of a three-dose primary vaccination series are recommended to receive a booster dose of either the Pfizer-BioNTech / Comirnaty or Moderna mRNA vaccines, unless medically ineligible for the mRNA vaccine.

Such persons who received an mRNA vaccine as their third dose should receive the booster dose about five months thereafter. However, those who received the Sinovac-CoronaVac vaccine as their third vaccine dose should do so at three months thereafter, due to lower antibody levels generated by the third vaccine dose.

Persons who were fully vaccinated with other WHO EUL vaccines are also recommended to receive a booster dose of an mRNA vaccine about five months after completion of their primary series vaccination.

*Recommendations for Sinovac-Coronavac should similarly apply to Sinopharm
