AstraZeneca Vaccine : Why Separate Approval For Siam Bioscience?

The AstraZeneca vaccine had earlier received conditional approval for use in Malaysia. However, they were manufactured by Medimmune Phama B.V. in The Netherlands.

The Malaysia National Pharmaceutical Regulatory Agency (NPRA) has to vet and approve AstraZeneca vaccine doses manufactured by other factories.

Just like how AstraZeneca vaccine doses manufactured by SK Bioscience had to first vetted for conditional approval, the same goes for these vaccine doses manufactured by Siam Bioscience.


AstraZeneca Vaccine : A Quick Primer!

The AstraZeneca COVID-19 vaccine, codenamed AZD1222, is a viral vector vaccine.

It uses a chimpanzee adenovirus – ChAdOx1 – which has been modified to prevent replication, to introduce a DNA sequence of the SARS-CoV-2 spike protein.

Once injected, the vaccine enters the cell and “teaches” it to produce the SARS-CoV-2 spike proteins and express them on its surface.

These spike proteins triggers the immune response to create antibodies that will protect you against the real SARS-CoV-2 virus.
