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.

Vaccination typically involves at least two injections about 6 weeks apart. This drives which important process in adaptive immunity?Select one alternative:B cell replicationgene rearrangementT cell replicationaffinity maturation

Vaccines require the adaptive immune system to be stimulated to generate long-lasting immunity. Name one type of antigen-presenting cell responsible for initiating the adaptive immune response.

The formation of memory immune responses is the objective of vaccination. Immunological memory is predominantly the function of which of the following?

This particular vaccine is important because the natural infection doesnot confer lifelong immunity:

Select all major characteristics of B cells.Multiple select question.Mature in the thymusProduces memory cells with clonal expansionRecognize antigens presented by MHC moleculesCarry out antibody-mediated immunity
