Let us introduce ourselves. We are the doctors you trust with your health and the health of your family across every stage of life, from the first checkups in infancy and childhood, to health care during pregnancy and adulthood, through management of chronic illness and aging. We are family physicians, pediatricians, internal medicine physicians, OB-GYNs, and infectious disease experts. Our commitment is not to politics, but to the absolute well-being of our patients and populations, and to providing them with best evidence-based health care.

We have an urgent, united message: Immunizations work, they are very effective and safe, and they save lives. Vaccines are among the most rigorously studied and effective tools in public health. Through widespread immunization, we have eradicated debilitating and fatal diseases that once caused serious illness, hospitalization, and death for millions of people.

But today, that legacy is at serious risk.

Misinformation, politicization of commonsense public health efforts, and sudden changes to federal vaccine guidance is creating mass confusion and diminishing trust in public health. As we head into another fall season sure to be marked by cases of flu, Covid-19, and RSV as well as the alarming reappearance of measles and pertussis, the stakes could not be higher. These respiratory illnesses are not abstract threats. They are real and dangerous, particularly to infants, seniors, pregnant patients and those with underlying health conditions.
