TWiV explains a cohort study of over one million Danish children which shows no evidence supporting an increased risk for autoimmune, atopic or allergic, or neurodevelopmental disorders associated with early childhood exposure to vaccines with aluminum-base adjuvants, and a study of antibodies induced by mRNA-1273 and NVX-CoV2373 COVID-19 vaccines which show that polyclonal antibodies against a single site on the spike N-terminal domain show immunodominance, high diversity, and limited cross-reactivity, indicating the need to direct antibody responses away from this site.
