Mass vaccination (75-90% of the population) is essential to achieve herd immunity, stop the circulation of the virus, and limit the emergence of resistant variants.

The idea that vaccination is a key tool for reducing viral circulation and protecting public health is widely supported by epidemiological data (observational public health data). The link between high vaccine coverage and reduced pressure on healthcare systems is well established by multiple global observational studies. Regarding variants, scientific literature confirms that viral replication in non-immunized individuals promotes the appearance of mutations, although viral evolution remains complex and multifactorial. The 75-90% figure cited for herd immunity was a theoretical estimate consistent with knowledge of initial strains, although the evolution of the virus has made this objective more difficult to maintain permanently. In summary, the discourse reflects the scientific consensus of the time regarding the importance of vaccination for limiting pandemic dynamics.
