The vaccine does not “guarantee” protection from other variants, but it does have some, more for some variants and apparently less for others (delta). But, the same can be said about prior infection: it does not “guarantee” protection from other variants either. The paper here provides evidence that even though neither of them “guarantee” immunity for other variants or reinfection, prior infection provides more protection from COVID-19 than currently used vaccines.
