Antibodies Respond Differently to Severe Versus Mild COVID-19. Researchers at Stanford Medicine found that COVID-19 antibodies preferentially target different parts of the SARS-CoV-2 virus in mild COVID-19 cases than they do in severe cases. People with severe COVID-19 have low proportions of antibodies that target the spike protein.

All that the agency has is preliminary data from pre-clinical and early clinical studies suggesting the vaccine triggers the production of antibodies and T-cells that target the virus. After vaccination, the surface spike protein is produced, priming the immune system to attack the SARS-CoV-2 virus if it later infects the body.

likely emerged through the genetic recombination of the Omicron BA.2.10.1 subvariants, where the two infected the same individual and swapped genetic material to create a new hybrid subvariant. This is concerning, as high-income countries are offering multiple boosters and throwing away unused vaccines.
J&J’s vaccine works by using an adenovirus as vector to deliver the genetic code of the Spike protein found on the coronavirus to the body. This causes the body to make the Spike protein, then produce antibodies against it that confer protection if virus infection occurs after the vaccination.
