Development of COVID-19 vaccine policy - United States, 2020-2023.

COVID-19 vaccines represent a great scientific and public health achievement in the face of overwhelming pressures from a global pandemic, preventing millions of hospitalizations and deaths due to COVID-19 vaccines in the United States. Over 675 million doses of COVID-19 vaccines have been administered in the United States, and over 80% of the U.S. population has had at least 1 dose of a COVID-19 vaccine. Over the course of the COVID-19 pandemic in the United States, over one million people died from COVID-19, and over six million were hospitalized. It has been estimated that COVID-19 vaccines prevented more than 18 million additional hospitalizations and more than 3 million additional deaths due to COVID-19 in the United States. From the beginning of the COVID-19 pandemic in 2020 through June 2023, ACIP had 35 COVID-19 focused meetings and 24 votes for COVID-19 vaccine recommendations. ACIP had the critical task of rapidly and thoroughly reviewing emerging and evolving data on COVID-19 epidemiology and vaccines, as well as making comprehensive population-based recommendations for vaccine policy and considerations for implementation through a transparent and evidence-based framework. Safe and effective COVID-19 vaccines, recommended through transparent policy discussions with ACIP, remain the best tool we have to prevent serious illness, hospitalization and death from COVID-19.

COVID-19 vaccine inquiries regarding children ages 5-11 years received by NIP-INFO.

We describe COVID-19 immunization inquiries regarding children age 5-11 years received by NIP-INFO, the Centers for Disease Control and Prevention's (CDC's) e-mail immunization inquiry service for health care professionals, at the launch of vaccination efforts for this age group, using descriptive qualitative analysis. From November 2 through November 30, 2021, NIP-INFO responded to 154 questions regarding COVID-19 vaccination for 5-11-year-old children. The most common questions related to formulation and dosage (39.6%), vaccination schedule (14.3%), CDC's educational materials for health care professionals (9.1%), and vaccine safety (8.4%); 16.2% of questions across all inquiry categories related to a vaccination error. We discuss CDC guidance related to the most common inquiries to inform further pediatric COVID-19 vaccination efforts, including future vaccination of younger pediatric age groups, which will be important to help to curb this pandemic.

Frequency and Cost of Vaccinations Administered Outside Minimum and Maximum Recommended Ages-2014 Data From 6 Sentinel Sites of Immunization Information Systems.

OBJECTIVE: To quantify vaccinations administered outside minimum and maximum recommended ages and to determine attendant costs of revaccination by analyzing immunization information system (IIS) records. STUDY DESIGN: We analyzed deidentified records of doses administered during 2014 to persons aged <18 years within 6 IIS sentinel sites (10% of the US population). We quantified doses administered outside of recommended ages according to the Advisory Committee on Immunization Practices childhood immunization schedule and prescribing information in package inserts, and calculated revaccination costs. To minimize misreporting bias, we analyzed publicly funded doses for which reported lot numbers and vaccine types were consistent. RESULTS: Among 3 394 047 doses with maximum age recommendations, 9755 (0.3%) were given after the maximum age. One type of maximum age violation required revaccination: 1344 (0.7%) of 194 934 doses of the 0.25-mL prefilled syringe formulation of quadrivalent inactivated influenza vaccine (Fluzone Quadrivalent, Sanofi Pasteur, Swiftwater, PA) were administered at age ≥36 months (revaccination cost, $111 964). We identified a total of 7 529 165 childhood, adolescent, and lifespan doses with minimum age recommendations, 9542 of which (0.1%) were administered before the minimum age. The most common among these violations were quadrivalent injectable influenza vaccines (3835, or 0.7% of 526 110 doses administered before age 36 months) and Kinrix (GlaxoSmithKline Biologicals, Rixensart, Belgium; DTaP-IPV) (2509, or 1.2% of 208 218 doses administered before age 48 months). The cost of revaccination for minimum age violations (where recommended) was $179 179. CONCLUSION: Administration of vaccines outside recommended minimum and maximum ages is rare, reflecting a general adherence to recommendations. Error rates were higher for several vaccines, some requiring revaccination. Vaccine schedule complexity and confusion among similar products might contribute to errors. Minimization of errors reduces wastage, excess cost, and inconvenience for parents and patients.

Notes from the Field: Injection Safety and Vaccine Administration Errors at an Employee Influenza Vaccination Clinic--New Jersey, 2015.

On September 30, 2015, the New Jersey Department of Health (NJDOH) was notified by an out-of-state health services company that an experienced nurse had reused syringes for multiple persons earlier that day. This occurred at an employee influenza vaccination clinic on the premises of a New Jersey business that had contracted with the health services company to provide influenza vaccinations to its employees. The employees were to receive vaccine from manufacturer-prefilled, single-dose syringes. However, the nurse contracted by the health services company brought three multiple-dose vials of vaccine that were intended for another event. The nurse reported using two syringes she found among her supplies to administer vaccine to 67 employees of the New Jersey business. She reported wiping the syringes with alcohol and using a new needle for each of the 67 persons. One of the vaccine recipients witnessed and questioned the syringe reuse, and brought it to the attention of managers at the business who, in turn, reported the practice to the health services company contracted to provide the influenza vaccinations.

The role of schools in strengthening delivery of new adolescent vaccinations.

Schools offer an opportunity to deliver new vaccines to adolescents who may not receive them in their medical home. However, school budgets and health priorities are set at the local level; consequently resources devoted to health-related activities vary widely. Partnering with schools requires soliciting buy-in from stakeholders at district and school levels and providing added value to schools. With appropriate resources and partnerships, schools could carry out vaccination-related activities from educating students, parents, and communities to developing policies supporting vaccination, providing vaccines, or serving as the site at which partners administer vaccines. Activities will vary among schools, but every school has the potential to use some strategies that promote adolescent vaccination.
