The Cochise County Board of Health convened on January 21, 2025, to discuss critical public health issues, focusing primarily on vaccine preventable diseases and the evolving landscape of viral infections. The meeting began with an overview of respiratory syncytial virus (RSV), highlighting its bimodal distribution affecting both young infants and older adults. Concerns were raised about increasing severe infections and hospitalizations among older adults, prompting discussions on the importance of vaccines.

The meeting then transitioned to a detailed explanation of the differences between viruses and bacteria. It was emphasized that while bacteria are single-celled organisms capable of independent reproduction, viruses require a host to replicate. This distinction is crucial for understanding treatment options, as bacterial infections are typically treated with antibiotics, whereas viral infections are managed with antiviral medications and vaccines.

A historical perspective on vaccines was provided, tracing back to Edward Jenner's work in the late 18th century with cowpox and smallpox. This foundational knowledge set the stage for discussions on the various types of vaccines available today, including live virus, killed virus, and mRNA vaccines. The latter, notably used in COVID-19 vaccines by Pfizer and Moderna, utilize messenger RNA to instruct cells to produce proteins similar to those found on the virus, thereby training the immune system without introducing the actual virus.

The meeting concluded with a focus on the upcoming 2024 COVID-19 vaccine, which is expected to target the JN1 lineage and KP2 strain, identified as potentially the most damaging variant circulating at that time. The Board of Health underscored the importance of vaccination in mitigating the impact of these evolving viral threats, particularly as new variants continue to emerge.

Overall, the meeting highlighted the ongoing challenges in public health related to infectious diseases and the critical role of vaccination in protecting vulnerable populations.
