Sinopharm vaccine … how it works … side effects

SINOPHARM’S BBIBP-CorV works by teaching the immune system to make antibodies against the SARS-CoV-2 coronavirus.

The antibodies attach to viral proteins, such as the so-called spike proteins that stud its surface.

Because the coronaviruses in BBIBP-CorV are dead, they can be injected into the arm without causing COVID-19.
