Solution
The process driven by the typical vaccination schedule involving at least two injections about 6 weeks apart is affinity maturation. This is a process in the adaptive immune system where B cells produce antibodies with increased "affinity" or binding strength to the antigen over time. The first injection introduces the antigen to the immune system, and the second injection (or any subsequent ones) provides a boost that helps to refine the immune response, leading to the production of higher-affinity antibodies.

Alterations in Immunization Schedules
However, numerous groups including ours have reported that neutralising titres in convalescent subjects are comparatively weak11,12,14,15,17 and appear to wane rapidly36,37,38. Here a simple two protein regime using licensure-friendly adjuvants was able to elicit superior binding and neutralising antibody responses. Prototypic vaccines induced strong GC activity in draining lymph nodes, driving maturation of S-specific B cells, and seeded memory T and B-cell responses in the blood. Overall, our study suggests that vaccination constitutes a more robust and reliable pathway to serological protection against SARS-CoV-2 than natural infection, similar to other pathogens such as human papillomavirus39,40.
