Unlike mRNA vaccines (Pfizer and Moderna) or viral-vector vaccines (AstraZeneca and J&J), Sinovac and Sinopharm biotechnology takes a more traditional route. The science is a whole lot more straightforward. Scientists grow the COVID19 virus in monkey liver cells. Then inactivate the virus by mixing it with a chemical (called beta-propiolactone). The chemical disables the virus by bonding to its genes and, thus, the virus can no longer replicate once injected. The vaccine, though, still looks and feels like COVID19 to our immune system, so it will trigger the memory immune response.
I'd love to see some updated info/analysis on Sinopharm. We have dear friends serving overseas (Indonesia) and if or when they have an opportunity to be vaccinated, it will most likely be with Sinopharm.
