EXCERPT
Vaccines are one of the greatest global public health achievements. Vaccine recommendations have been critical to the global eradication of smallpox and the elimination of polio, measles, rubella, and congenital rubella syndrome in the US. They have also dramatically decreased cases of hepatitis, meningitis, mumps, pertussis (whooping cough), pneumonia, tetanus, and varicella (chickenpox), and prevented cancers caused by hepatitis B virus and human papillomaviruses.1 Recent scientific advancements enabled the accelerated development, production, and evaluation of COVID-19 vaccines, leveraging novel technologies that are estimated to have prevented approximately 1.6 million hospitalizations and 235 000 deaths in the US alone.2
