If we were as vulnerable to virus as many believe, humanity would not have survived as long as we have. Other than antibodies, we have developed other defenses over the eons. This article:
https://www.bath.ac.uk/announcements/we-are-mutating-sars-cov-2-but-it-is-evolving-back/ describes how humans weaken a virus over time. Indeed, along with good quarentining (preventing the survival of more fit mutations), the SARS virus was taken down in this manner. Antibody stimulating vaccines are good; but, attacking that one thing which makes the virus our enemy, its RNA, is better.
