So yeah my question again - why are these vaccines quoted from the link you provided not the main ones we talk about? The ones most likely to work correctly from my basic logic. I also notice they are made by sinopharm and sinovac which I assume are chinese groups due to the Sino. So was there some reason we could not or would not make a vaccine in this straight forward way because they already did or something? I actually want to talk about these before myself speculating on reasons we have focused on the pfiezer and moderna MRNA vaccines.
1) WHOLE VIRUS VACCINE
Vaccines include: Sinopharm, Sinovac
Number of doses required: 2 doses, intramuscular
Other licensed vaccines that use this type of technology: Hepatitis A, polio, rabies (all inactivated type)
What to know: The whole virus vaccine uses a weakened or deactivated form of the pathogen that causes COVID-19 to trigger protective immunity to it.
The two vaccines mentioned above – Sinopharm and Sinovac – both use inactivated pathogens, therefore they cannot infect cells and replicate, but can trigger an immune response.
Benefits: According to Gavi, the Vaccine Alliance (GAVI), the advantages of an inactivated whole virus vaccine include the fact its technology is well established, it is suitable for people with compromised immune systems, and it’s relatively simple to manufacture.
Challenges: Booster shots may be required.
