Unpacking intersectional inequities in flu vaccination by sexuality, gender, and race-ethnicity in the United States.
This study examined influenza vaccination inequities at the intersection of sexuality, gender, and race-ethnicity using data from the 2013 to 2018 National Health Interview Survey (N = 166,908). It found that White gay men had the highest vaccination rate (56%), while Black bisexual women had the lowest rate (23%). Sexual minority women (Black or Hispanic) had lower vaccination rates than heterosexual women, but sexual minority men had higher or similar vaccination rates than heterosexual men. While economic enabling, noneconomic enabling, and need-based factors all help to explain a substantial portion of these gaps, they cannot explain all the disadvantages faced by Black lesbian, bisexual, heterosexual women, and Black heterosexual men.

Anti-spike antibody durability after SARS-CoV-2 vaccination in adolescent solid organ transplant recipients.
This study examined COVID-19 m-RNA vaccine antibody responses 6 months following the third vaccine dose (D3) of the BNT162b2 mRNA vaccination among adolescent solid organ transplant recipients (aSOTRs). The 34 participants were surveyed after they received the third dose of the vaccine and were sampled at 1-, 3-, and 6-months post-D3. All had positive anti-RBD antibody titers 6 months post-D3. Variations in titers occurred between 3 and 6 months post-D3, with 29% having decreased antibody levels at 6 months compared to 3 months and 7% reporting increased titers at 6 months. The remaining 18 had unchanged antibody titers compared to 3-month post-D3 levels. A total of 12% reported breakthrough infection within 6 months and 9% reported infection after 6-12 months following the third dose of the SARS-CoV-2 mRNA vaccine.

Impact of healthcare location concordance on receipt of preventive care among children whose parents have a substance use and/or mental health diagnosis.
This study examined the association of children with parents with >1 substance use and/or other mental health (SU/MH) diagnoses and parent-child clinic concordance with rates of well-child checks (WCCs) and childhood vaccinations. This retrospective cohort study used electronic health record data from the OCHIN network of community health organizations (CHOs) from 2010 to 2018. This included 280 CHOs across 17 states and 41,413 parents with >1 SU/MH diagnosis linked to 65,417 children ages 0 to 17 years, each with >1 visit to an OCHIN clinic during the study period. The authors found that among children utilizing the same clinic as their parent versus children using a different clinic (reference group), there were greater WCC rates in the first 15 months of life; no difference in WCC rates in ages 3 to 17; higher odds for vaccine completion before age 2; and lower odds for vaccine completion before age 18.

Latino adolescent-mother language concordance, neighborhood deprivation, and vaccinations in community health centers.
Researchers examined the association between adolescent-mother language concordance and neighborhood social deprivation with adolescent vaccination completion in order to understand social/family factors related to Latino adolescent vaccination. They used a multistate, EHR-based dataset of community health center patients to compare three Latino groups; their sample included over 56,000 adolescent-mother dyads. Their findings indicated that English-preferring adolescents with Spanish-preferring mothers had the highest completion rates. The researchers concluded that future studies could attempt to understand what advantage this language dyad may have in adolescent vaccination completion.

County-level barriers in the COVID-19 vaccine coverage index and their associations with willingness to receive the COVID-19 vaccine across racial/ethnic groups in the U.S.
This study examined whether county-level vaccination barriers varied across racial/ethnic groups in the U.S., if they were associated with willingness to receive the COVID-19 vaccine, and if they differed across racial/ethnic groups. Data was taken from the REACH-US study. County-level vaccination barriers were measured using the COVID-19 Vaccine Coverage Index. Results showed that American Indian/Alaska Native, African American, Hispanic/Latino, and Multiracial adults were more likely than White adults to live in counties with higher overall county-level vaccination barriers. Higher sociodemographic barriers were associated with less willingness to receive the COVID-19 vaccine. History of low vaccination was associated with less willingness to receive the COVID-19 vaccine among African American adults. The researchers concluded that future vaccination programs should include efforts accounting for structural barriers to preventive healthcare and their intersection with sociodemographic factors.

Safety and immunogenicity of live viral vaccines in a multicenter cohort of pediatric transplant recipients.
This study’s objective was to determine the safety and immunogenicity of live vaccines in pediatric liver and kidney transplant recipients. This cohort study included 281 children, of which 270 had received a liver transplant, 9 a kidney transplant, and 2 were liver-kidney transplant recipients. None of the children included had completed their primary measles-mumps-rubella (MMR) and varicella-zoster virus (VZV) vaccine series and/or had displayed nonprotective serum antibody levels at enrollment between January 1, 2002, and February 28, 2023. Safety data was collected after these transplant recipients had received 1 to 3 doses or MMR vaccine and/or 1 to 3 doses of VZV vaccine. The median time from transplant to enrollment was 6.3 years, with the median age at first posttransplant vaccine 8.9 years. The majority of children developed protective antibodies following vaccination (107 of 149 varicella, 130 of 152 measles, 100 of 120 mumps, and 124 of 125 rubella). One year post vaccination, the majority of children who initially mounted protective antibodies maintained this protection (34 of 44 varicella, 45 of 49 measles, 35 of 42 mumps, 51 of 54 rubella). Five children developed varicella, all of which resolved within 1 week, and there were no cases of measles or rubella and no episodes or graft rejection within 1 month of vaccination. There was also no association between antibody response and immunosuppression level at the time of vaccination.

The benefits and costs of U.S. employer COVID-19 vaccine mandates.
This study examined the benefits and costs of U.S. employer COVID-19 mandates for federal employees and contractors and for some healthcare and private sector workers if there had not been major challenges in court that halted or delayed the mandates. The authors estimated the direct costs and health-related benefits that would have accrued if these vaccination requirements had been implemented as intended. Compared with the January 2022 vaccination rates, they found that the mandates could have led to 15 million additional vaccinated individuals, increasing the overall proportion of the fully vaccinated U.S. population from 64% to 68%. They examined scenarios involving the emergence of a novel, more transmissible variant, against which vaccination and previous infection offer moderate protection, and found that the estimated net benefits are potentially large. They estimated that they reach almost $20,000 per additional vaccinated individual, with more than 20,000 total deaths averted over the 6-month period assessed. For other scenarios involving a fading pandemic, existing vaccination-acquired or infection-acquired immunity provides sufficient protection, and the mandates' benefits are unlikely to exceed their costs. They believe that mandates may be most useful when the consequences of inaction are catastrophic. However, they did not compare the effects of mandates with alternative policies for increasing vaccination rates or for promoting other protective measures, which may receive stronger public support and be less likely to be overturned by litigation.

Immunization of solid organ transplant candidates and recipients: a 2022 update.
The authors discussed the dissemination and implementation of up-to-date vaccine recommendations to aid primary care providers and multi-disciplinary transplant team members taking care of solid organ transplant patients. Key recommendations included: All age-appropriate vaccines should be administered pretransplant; nonimmune liver and kidney transplant recipients on low-dose immunosuppression can be given live vaccines posttransplant under careful medical observation; immunizations should be a prioritized part of pre- and posttransplant care.

Racial and ethnic disparities in excess deaths after COVID-19 vaccine deployment among persons with kidney failure.
COVID-19 resulted in clear racial/ethnic disparities in excess deaths among persons with kidney failure. It is not clear whether or how these disparities changed throughout the pandemic, especially after the deployment of COVID-19 vaccines. The purpose of this study was to examine disparities in excess mortality for the Medicare population with kidney failure from March 2020, through December 2021. The study found that there were 686,719 patients with kidney failure in January 2020. Researchers reported an increase in excess deaths beginning March 1, 2020, with a peak in January 2021. From March 1, 2020, through January 30, 2021, and there were substantial disparities in excess deaths across racial/ethnic groups. The number of excess deaths was 5582, 4303, and 2679 for non-Hispanic White, non-Hispanic Black, and Hispanic patients, respectively. The percent excess deaths was 31.9% for Hispanic patients, 27.5% for non-Hispanic Black patients, and 16.4% for non-Hispanic White patients. After the wide distribution of COVID-19 vaccines since the end of January 2021, the lowest percent excess deaths was observed among Hispanic patients, followed by Black patients, and White patients.

Pediatric hematology and oncology physician and nurse practitioner views of the HPV vaccine and barriers to administration.
This study’s goal was to examine provider views regarding HPV vaccination for pediatric survivors of cancer and pediatric patients with sickle cell disease. The authors conducted qualitative interviews with 20 pediatric hematology/oncology physicians and nurse practitioners. They found that 90% of interviewees support HPV vaccination in their population. The number of providers who reported that they counsel about HPV or provide HPV vaccination was 45%, even in stem cell and sickle cell clinics, where other childhood vaccines are commonly provided. Clinicians identified provider-level, clinic-level, and system-level barriers to giving the HPV vaccination, that included but was not limited to time/flow constraints, lack of resources, and continued education regarding the HPV vaccine.

Impact of the COVID-19 vaccination mandate on the primary care workforce and differences between rural and urban settings to inform future policy decision-making.
The purpose of this cross-sectional study was to determine how vaccine mandates affect the healthcare workforce. Between October 28, 2021- November 18, 2021, following implementation of a COVID-19 vaccination mandate for healthcare personnel, the researchers conducted a survey of Oregon primary care clinic staff. The survey included 19 questions that assessed the clinic-level effects of the vaccination mandate. Study outcomes included job loss among staff, receipt of an approved vaccination waiver, new vaccination among staff, and the perceived significance of the policy on clinic staffing. Staff from 80 clinics across 28 counties completed surveys, representing 38 rural and 42 urban clinics. The study found that clinics reported job loss (46%), use of vaccination waivers (51%), and newly vaccinated staff (60%). Significantly more rural clinics (compared to urban) used medical and/or religious vaccination waivers (71% vs 33%) and reported significant impact on clinic staffing (45% vs 21%). There was also a non-significant trend toward more job loss for rural compared to urban clinics (53% vs. 41%). Qualitative analysis revealed a decrease in clinic morale and mixed opinions of the vaccination mandate.

Effectiveness and feasibility of three types of parent reminders to increase adolescent human papillomavirus (HPV) vaccination.
Efforts to boost human papillomavirus (HPV) vaccination rates among adolescents have seen moderate success with the use of parent notifications. Nonetheless, there is limited research on the comparative efficacy and practicality of various HPV reminder methods in settings with restricted resources. The purpose of this quasi-experimental study (2016-2017) assessed the impact of three types of parent reminders (written correspondence, automated phone calls, and SMS messages) on HPV vaccine uptake for the subsequent dose among 12-year-olds at a prominent Federally Qualified Health Center in Los Angeles County. The researchers matched six clinics into three groups, randomly allocating one clinic from each group to either intervention or control. The intervention clinics were randomly assigned one of the three reminder methods. The researchers determined the rates of vaccine uptake for the next dose and analyzed intervention outcomes using logistic regression models. The proportion of successfully delivered reminders for each method was used as a measure of feasibility. The study included 877 12-year-olds due for an HPV vaccine dose (47% female, more than 85% Latino). The study found that after a 4-month follow-up, 23% of those in the intervention group received an HPV vaccine dose, compared to just 12% in the control group. Overall, receiving any reminder led to higher rates of the next-required HPV vaccine compared to standard care (p = 0.046). Notable improvements were seen with SMS reminders (p = 0.036) and among boys (p = 0.006). Automated phone calls proved to be the least feasible method. Text message reminders are both effective and practical in encouraging HPV vaccination.

Clinical phenotypes of immediate first-dose reactions to mRNA COVID-19: a multicenter latent class analysis.
The objectives of this retrospective study were to define distinct clinical phenotypes of immediate reactions after dose 1 of mRNA COVID-19 vaccination, and to assess the relation of clinical phenotype to mRNA COVID-19 vaccine second dose tolerance. Researchers identified 265 patients who experienced dose-1 immediate reactions with 3 phenotype clusters: limited or predominantly cutaneous, sensory, or systemic. Of these, 223 patients received a second dose and 200 tolerated the second dose; sensory cluster (numbness or tingling) was associated with a higher likelihood of second dose intolerance, but this finding did not persist when accounting for objective signs.

Engaging same-day peer ambassadors to increase coronavirus disease 2019 vaccination among people experiencing unsheltered homelessness in Los Angeles County: a hybrid feasibility-evaluation study.
This study’s goal was to evaluate the feasibility and acceptability of engaging unhoused peer ambassadors (PAs) in COVID-19 vaccination efforts to reach people experiencing unsheltered homelessness in Los Angeles County. A total of 117 PAs were enrolled at 103 events, participating for an average of 2 hours. Findings showed that 197 additional people were vaccinated over 167 PA hours, accounting for >25% of all vaccines given at these events, indicating that recruiting same-day unhoused PAs is a feasible, acceptable, and preliminarily effective technique to increase COVID-19 vaccination in unsheltered settings.

Impact of a multi-level, multi-component, system intervention on HPV vaccination in a federally qualified health center.
This paper evaluates the effectiveness of a multi-component, system-level intervention to improve human papillomavirus (HPV) vaccination rates in Federally Qualified Health Center (FQHC) clinics. The eight participating clinics were randomly assigned to study condition (four intervention, four usual care) that serve a primarily low-income Latino population. The intervention included parent reminders for HPV vaccine series completion, provider training, clinic-level audit and feedback, and workflow modifications to reduce missed opportunities for vaccination. The authors compared HPV vaccination rates among patients, ages 11 to 17 during a 12-month preintervention period and a 15-month intervention period. There was a greater increase in vaccination completion rates among boys, but not girls.

Antibody response to three SARS-CoV-2 mRNA vaccines in adolescent solid organ transplant recipients.
The purpose of this observational cohort study was to assess whether a third SARS-CoV-2 vaccine would improve immunogenicity in adolescent solid organ transplant recipients (SOTRs), and to report the antibody response and safety of a third mRNA vaccine dose (D3) in adolescent SOTRs. Forty-two participants received three BNT162b2 doses and one received three mRNA-1273 doses. Participants were 6-13 years from transplant (median 10 [IQR]), and heart transplant was the most common procedure, in 41.9% of the participants. 9.3% of participants reported pre-D1 SARS-CoV-2 infections and 9.3% reported breakthrough infections. The study found that 88.4% of adolescent SOTRs had positive antibody responses 1 month post-D3, an increase from 63–73% post-D2. 54.5% of participants with prior negative responses seroconverted and 100% with positive responses increased or remained at maximum titer. Titers remained stable 3 months post-D3. There were no vaccine-related adverse events and four breakthrough infections. The researchers concluded that although this was a convenience sample, the results suggest there is an antibody response benefit to a third SARS-CoV-2 vaccine in adolescent SOTRs.

Influenza vaccination in Massachusetts jails: a mixed-methods analysis.
The objectives of this study were to survey health administrators in Massachusetts county jails about institutional influenza vaccine policies and practices and estimate influenza vaccination rates in Massachusetts jails from 2013 to 2020. Findings showed that influenza vaccination rates in Massachusetts jails were low, and delivery practices in jails varied. The authors noted that lack of influenza vaccinations in jails is a gap in health care that needs to be prioritized, especially considering the current COVID-19 pandemic. They suggested that further investigations for effective and equitable vaccination in this population should involve people who are incarcerated and people who make influenza vaccine policies in jails.

Rapid progress in our understanding of COVID-19 vaccine allergy: a cause for optimism, not hesitancy.
This paper is a review of current understanding of COVID-19 vaccine allergy. Rapid progress has been made over the past several years in large part due to important research efforts from individuals in the allergy community. Better data has shown safety of repeat vaccination despite an initial reaction. The review ran from December 2020 through early 2022.

Adolescents with vulvar ulcers: COVID-19 disease, COVID-19 vaccines, and the value of case reports.
The author indicates that there are too few cases reporting aphthosis after COVID disease or COVID-19 vaccination to infer a statistical association, but that case reports are a valuable source of rich details about conditions that are difficult to study with more rigorous designs and can be synthesized to help guide medical care. She recommends that it is time for a high-quality systematic review of vulvar aphthosis in order for clinicians to incorporate the existing evidence into decision-making and best care for patients.

The purpose of this systematic review and meta-analysis of case studies and case reports was to assess the risk of severe immediate allergic reactions to a second dose of SARS-CoV-2 mRNA vaccine in people who experienced an immediate allergic reaction to the first dose. The researchers evaluated the World Health Organization Global Coronavirus database, Web of Science, MEDLINE, and Embase from the date of inception through October 4th, 2021. The main outcomes and measures were a risk of severe immediate allergic reaction and repeated severe immediate allergic reactions with a second vaccine dose. The study found that among 22 studies of SARS-CoV-2 mRNA vaccines, 1366 individuals had immediate allergic reactions to their first vaccination. Of these, 87.8% were women with a mean age of 46.1 years. Six patients developed severe immediate allergic reactions after their second vaccination, 232 developed mild symptoms, and 1360 tolerated the dose. Among 78 persons with severe immediate allergic reactions to their first SARS-CoV-2 mRNA vaccination, 4 people had a second severe immediate reaction, and 15 had non-severe symptoms. There were no deaths. The study concluded that in a supervised setting equipped to manage severe allergic reactions, revaccination of individuals with an immediate allergic reaction to a first SARS-CoV-2 mRNA vaccine dose can be safe.

Parent intentions to vaccinate children with autism spectrum disorder against COVID-19.
This study’s purpose was to investigate associations between parent vaccine confidence and intentions to have their child with autism vaccinated with the COVID-19 vaccine. A cross-sectional, web-based survey of 332 parents of children with autism spectrum disorder who were members of an integrated healthcare system in Southern California was conducted from May to July 2021. Approximately 35% of parents were going to vaccinate their child against COVID-19. Positive vaccine beliefs, healthcare provider trust, or parent vaccination status were associated with intention to vaccinate.

Antibody response to 2-dose SARS-CoV-2 mRNA vaccination in pediatric solid organ transplant recipients.
While many adult solid organ transplant recipients (SOTRs) have impaired antibody response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, pediatric SOTRs’ response has not been assessed. In this article, the researchers reported the immunogenicity and safety of BNT162b2 mRNA vaccination in pediatric SOTRs.

Increasing HPV vaccination among low-income, ethnic minority adolescents: effects of a multicomponent system intervention through a county health department hotline.
The human papillomavirus (HPV) vaccine has cancer prevention benefits, yet low uptake. The purpose of the study was to evaluate an intervention intended to improve vaccine uptake in low-income, ethnic minority adolescents using a telephone hotline to seek county health department services. The researchers recruited participants through randomization of health department hotline callers who were caregivers of never-vaccinated adolescents aged 11-17. The intervention included multi-lingual print and telephone education and personalized referral to a low cost or free provider of vaccines. Participants completed baseline, 3-month, and 9-month telephone surveys. The study found that by the end of the 9-month follow up period, the HPV vaccination rates had increased, however there were no differences between the intervention (45%) and control (42%) groups. The researchers also observed significant improvements in perceived HPV knowledge, perceived HPV risk, and barriers to vaccination. The study concluded that the county hotline intervention did not produce a greater increase in HPV vaccine rates in the intervention group than the group without the intervention. The study authors recommend that future studies should evaluate interventions which are more intensive and address accessing and using services in complex, safety net settings. The authors also noted that because 44% of unvaccinated adolescents in both the intervention and control groups received at least one dose of the vaccine during the study period, investigators of future studies should be aware of the potential priming effects of participation in the study, which may impact the results of interventions.

mRNA COVID-19 vaccine safety in patients with previous immediate hypersensitivity to pegaspargase.
The authors sought to understand the safety of PEG2000-containing mRNA COVID vaccines in patients who reported a label of immediate pegaspargase hypersensitivity. They found that all 19 studied patients tolerated their first dose of Pfizer-BioNTech SARS-CoV-2 vaccine with no symptoms. Subsequently, all 19 patients tolerated their second doses uneventfully as well.

A risk prediction model to identify newborns at risk for missing early childhood vaccinations.
Approximately 30% of US children aged 24 months have not received all recommended vaccines. This retrospective cohort study aimed to develop a prediction model to identify newborns at high risk for missing early childhood vaccines. The investigators concluded that their prediction model using information readily available in birth hospitalization records consistently identified newborns at high risk for undervaccination.
