It’s vaccine season, and an excellent opportunity to prevent or reduce the impact of viruses such as COVID-19, influenza and measles. Making good choices could be even more difficult than during the COVID-19 pandemic because our public health circumstances have worsened dramatically. Infectious diseases and vaccines evolve, sometimes rapidly, so the best advice can change over time. Doing so can keep you motivated and focused during a public health crisis. Your personal choices and flexibility are your best tools to avoid a virus, survive if infected, and even perhaps even grow stronger.
