Coronavirus disease 2019 has become a widespread public health crisis across the globe, requiring multiple approaches to containment, treatment, and prevention. Vaccines are an important tool to prevent morbidity and mortality from this devastating virus. Ensuring direct administration of vaccines into target tissue helps provide an optimal immune response while decreasing unintended adverse effects. Point‐of‐care ultrasound can better assist clinicians to determine appropriate needle length and penetration level especially in special populations. Examples include patients who are obese, pregnant, or with refractory lymphedema, and those living in areas where needle supply is unstable or insufficient.
