Iowans: Save a life. Get the shot.

The four pillars of medical ethics are lack malevolence, benefit exceeds risk, equality, and patient consent. It is with ease one can note the COVID-19 vaccines were designed without malicious intent, benefits far exceeds the rare; however, real side effects, and it is available to all who are eligible and desire to receive it.

Patient consent is the pillar which is most challenged and with good reason. Each patient has unique biology and medical care must be individualized. Your physician can help navigate concerns and separate fact from fiction.

The unwelcomed delta variant has decreased the efficacy of the vaccine; however, the vaccine continues to prevent morbidity and mortality. The suffering created by the virus has burdened many families and has challenged medical resources. Contingencies and careful planning have been employed to ensure patients receive high quality care when it is needed.

Unfortunately, these endeavors require deferring medical care, which leads to poor health in the future. A fully vaccinated community will lessen the burden on our community’s shared public resources and safeguard the continued provision of routine/preventive care. The vaccine will prevent death, which will limit the number of widowers and orphans produced by the contagion.

After review and reflection on the measurable and unmeasurable factors, I continue to recommend vaccination to patients with unbridled enthusiasm.

You have been asked to sacrifice, with observable courage, so much in the last year. And it is accompanied by that observation of courage, that “once more unto the breach” is called upon you, to receive the COVID-19 vaccine. Do it for you. Do it for others.

Our battle is not over. More lives must and can be saved.
