Influence of respiratory disease experiences on Covid-19 vaccine acceptance
Introduction: Respiratory diseases, including influenza (flu) and respiratory syncytial virus, continue to be major health concerns globally. The onset of COVID-19 further compounded these issues, making it important to examine public attitudes toward vaccination and understanding of respiratory diseases. This study explores factors influencing decisions to receive the latest COVID-19 vaccine, focusing specifically on the role of prior respirator…
The Voices on Vax Campaign
We recommend using techniques to maximize engagement by the priority population, conducting in-person outreach, incorporating mixed methods data collection, and providing a mix of structured training and creative freedom to youth ambassadors
LetsTalkShots
Introduction Vaccine hesitancy is a global health threat undermining control of many vaccine-preventable diseases. Patient-level education has largely been ineffective in reducing vaccine concerns and increasing vaccine uptake. We built and evaluated a personalized vaccine risk communication website called LetsTalkShots in English, Spanish and French (Canadian) for vaccines across the lifespan. LetsTalkShots tailors lived experiences, credible so…
Evaluation of online videos to engage viewers and support decision-making for Covid-19 vaccination
Background Vaccine hesitancy has hampered the control of COVID-19 and other vaccine-preventable diseases. Methods We conducted a national internet-based, quasi-experimental study to evaluate COVID-19 vaccine informational videos. Participants received an informational animated video paired with the randomized assignment of (1) a credible source (differing race/ethnicity) and (2) sequencing of a personal narrative before or after the video address…
Trust in government, intention to vaccinate and Covid-19 vaccine hesitancy
BACKGROUND: There is widespread hesitancy towards COVID-19 vaccines in the United States, United Kingdom, and Australia. OBJECTIVE: To identify predictors of willingness to vaccinate against COVID-19 in five cities with varying COVID-19 incidence in the US, UK, and Australia. DESIGN: Online, cross-sectional survey of adults from Dynata's research panel in July-September 2020. PARTICIPANTS, SETTING: Adults aged 18 and over in Sydney, Melbourne, Lo…

Novel vaccine safety issues and areas that would benefit from further research
Vaccine licensure requires a very high safety standard and vaccines routinely used are very safe. Vaccine safety monitoring prelicensure and postlicensure enables continual assessment to ensure the benefits outweigh the risks and, when safety problems arise, they are quickly identified, characterised and further problems prevented when possible. We review five vaccine safety case studies: (1) dengue vaccine and enhanced dengue disease, (2) pandem…
Patient Decision Making Related to Maternal and Childhood Vaccines
Immunization is one of the most effective ways to prevent infectious diseases. However, vaccination rates are suboptimal in the United States. Obstetric providers are critical in influencing vaccine decision making among pregnant women, as trust between a patient and provider may facilitate willingness to accept vaccination. Little is known about how power between a patient and provider affects vaccine acceptance. This study explored pregnant wom…
Latent Class Analysis of Maternal Vaccine Attitudes and Beliefs
Background. Maternal vaccine coverage is suboptimal, and a substantial proportion of parents have concerns about vaccines. Most parents seek out vaccine information during and immediately after their first pregnancy. No study to our knowledge has analyzed survey data to identify homogeneous groups of pregnant women based on their vaccine attitudes and beliefs. Aims. To identify homogeneity among groups of pregnant women based on their vaccine att…
Shouting at each other into the void
In 2015, California passed Senate Bill 277 and became the third state in the United States to ban all nonmedical exemptions from school immunization requirements, effectively prohibiting religious and personal belief exemptions. This attracted grassroots opposition and considerable debate among vaccine hesitant factions online. This mixed-methods study used quantitative linguistic analysis, semantic network analysis, and content analysis techniqu…
California’s Senate Bill 277
Objectives. To understand the experiences of local health jurisdictions with Senate Bill 277 (SB277), the California law that eliminated nonmedical vaccine exemptions for public- and private-school entry. Methods. We conducted semistructured telephone interviews with health officers and local health department (LHD) staff in California between August and September 2017. Results. Two overall themes emerged: (1) vague legislative and regulatory lan…
Association Between Vaccine Refusal and Vaccine-Preventable Diseases in the United States
IMPORTANCE: Parents hesitant to vaccinate their children may delay routine immunizations or seek exemptions from state vaccine mandates. Recent outbreaks of vaccine-preventable diseases in the United States have drawn attention to this phenomenon. Improved understanding of the association between vaccine refusal and the epidemiology of these diseases is needed. OBJECTIVE: To review the published literature to evaluate the association between vacc…

Vaccine Refusal, Mandatory Immunization, and the Risks of Vaccine-Preventable Diseases
Vaccines are among the most effective prevention tools available to clinicians. However, the success of an immunization program depends on high rates of acceptance and coverage. There is evidence of an increase in vaccine refusal in the United States and of geographic clustering of refusals that results in outbreaks. Children with exemptions from school immunization requirements (a measure of vaccine refusal) are at increased risk for measles and…
Availability of Litigation as a Public Health Tool for Firearm Injury Prevention
The Protection of Lawful Commerce in Arms Act (PLCAA), enacted in 2005, grants the firearm industry broad immunity from liability. The PLCAA not only prevents most people from receiving compensation for their firearm-related injuries, it erodes litigation’s ability to serve its public health role of providing manufacturers with a financial incentive to make their products safer. When the viability of the vaccine industry was threatened in the 198…
Support for immunization registries among parents of vaccinated and unvaccinated school-aged children
Parental support for registries was relatively high. Parental support for immunization registries may increase with greater parental awareness of the risks of vaccine preventable diseases and utility of vaccination
Factors Associated With Refusal of Childhood Vaccines Among Parents of School-aged Children
BACKGROUND: The rate of nonmedical exemptions to school immunization requirements has been increasing, and children with exemptions have contributed to outbreaks of vaccine-preventable diseases. OBJECTIVES: To determine why parents claim nonmedical exemptions and to explore differences in perceptions of vaccines and vaccine information sources between parents of exempt and fully vaccinated children. DESIGN: Case-control study. SETTING: Colorado, …
Exemptions to School Immunization Requirements
Objectives. Our goal was to determine whether school-level variability in implementation of immunization requirements is associated with the likelihood of a child having received an exemption to school immunization requirements. Methods. We surveyed 1000 school immunization personnel in Colorado, Massachusetts, Missouri, and Washington. We explored associations between school implementation of immunization requirements and the likelihood of a chi…
Public Health and the Politics of School Immunization Requirements
Compulsory vaccination has contributed to the enormous success of US immunization programs. Movements to introduce broad “philosophical/personal beliefs” exemptions administered without adequate public health oversight threaten this success. Health professionals and child welfare advocates must address these developments in order to maintain the effectiveness of the nation’s mandatory school vaccination programs. We review recent events regarding…
Enhancing Public Confidence in Vaccines Through Independent Oversight of Postlicensure Vaccine Safety
The National Immunization Program of the Centers for Disease Control and Prevention is responsible for controlling infectious diseases through vaccination, but the program also plays a key role in postlicensure vaccine safety assessment. The time has come to separate postlicensure vaccine safety assessment from vaccine risk management as recommended by the National Research Council of the National Academy of Sciences. The National Transportation …
