MedicalResearch.com Interview with: Manuel García Cenoz MD,  PhDInstituto de Salud Pública de Navarra - IdiSNA, Pamplona, SpainCIBER Epidemiología y Salud Pública, Madrid MedicalResearch.com: What is the background for this study? Response: Neisseria meningitidis is a major cause of severe disease in infants and children. After the introduction of serogroup C vaccines, serogroup B meningococcus has become the main cause of invasive meningococcal disease in Europe. The multicomponent protein-based meningococcal B vaccine (4CMenB, Bexsero, GSK) was licensed in the European Union in 2013. Its authorization was based on immunogenicity studies. Although some countries have introduced the 4CMenB vaccine into the publicly-funded infant immunization programs, the low incidence of the disease has limited the conduct of post-commercialization studies of effectiveness.Meningococcal B vaccine began to be used in Spain in children in 2014, recommended by the Spanish Association of Pediatrics, and paid by their families as it was not publicly-funded. We have conducted a nationwide study including all confirmed cases of invasive meningococcal disease in Spain between October 2015 and September 2019 in children aged two months to five years.

MedicalResearch.com Interview with: Dr. Didem Egemen PhD Statistician, Division of Cancer Epidemiology & Genetics National Cancer Institute MedicalResearch.com: What is the background for this study? Response: Persistent infection with human papillomavirus (HPV), a sexually transmitted disease, is the cause of virtually all cervical cancers. Various studies have reported high effectiveness of HPV vaccination in preventing HPV infection and cervical cancer, particularly when administered at early ages. In this study, we looked at the proportion of females eligible for vaccination (<26 years of age in 2006 when the vaccine was FDA approved) who were unvaccinated, vaccinated against HPV before sexual debut, and vaccinated after debut. Then we estimated the prevalence of HPV 16 and 18, the two HPV genotypes that cause most cervical cancers, in each subset. (more…)

MedicalResearch.com Interview with: Dr Emma Wall Senior Clinical Research Fellow, UCLH-Crick Legacy study Consultant Infectious Diseases UCLH MedicalResearch.com:  What is the background for this study?  Response: Since April 2022, both the UK and US have changed their COVID-19 isolation and testing policies. The impact these changes in the guidance and vaccination on community-acquired COVID-19 caused by recent SARS-CoV-2 variants of concern (VOC) has not been fully tested, including infections with BA.2. We aimed to characterise both symptoms and viral loads over the course of COVID-19 infection in otherwise-healthy, vaccinated, non-hospitalised adults, to assess whether current guidance remains justified. All participants were included in the UCLH-Crick Legacy study, a prospective, observational cohort study of otherwise healthy adults who have been taking part in regular workplace testing for SARS-CoV-2 in London We sent swabs by same-day courier every other day to all adults who reported a positive PCR or lateral flow test to the study team up to day 10 after the start of each infection. We confirmed which variant caused the infection by PCR and sequencing. All participants completed linked symptom diaries. We compared symptoms and changes in the amount of virus detected in the nose and throat during infection between study participants reporting COVID-19 caused by VOCs Delta and Omicron BA.1 and BA.2. We then analysed how many of our participants would meet current UK/US isolation guidelines. (more…)

MedicalResearch.com Interview with: Bianca V. Sanchez Department of Medical Education Geisinger Commonwealth School of Medicine Scranton, Pennsylvania MedicalResearch.com: What is the background for the study? Response: Hispanic populations have been disproportionately affected by the COVID-19 pandemic, as evident by their increased rate of infection with the virus, hospitalizations, and mortality. Previous literature has indicated that many of these individuals demonstrate increased rates of vaccine hesitancy, subsequently increasing their risk for infection. This study aimed to characterize the reasoning behind vaccine hesitancy in Hispanic populations in the hopes of addressing their concerns through targeted educational interventions. (more…)

MedicalResearch.com Interview with: Ronen Arbel, PhD Outcomes Research, Community Medical Services Division Clalit Health Service Tel Aviv, Israel Director, Maximizing Health Outcomes Research Lab Sapir College, Sderot, Israel.  MedicalResearch.com: What is the background for this study? Response: The emergence of the SARS-CoV-2 delta variant and reduced effectiveness over time of the BNT162b2 vaccine (Pfizer-BioNTech) led to a recent Coronavirus 2019 disease (Covid-19) resurgence in early vaccinated populations. The Israeli Ministry of Health was the first in the world to approve a third (booster) dose of BNT162b2 to cope with this resurgence. (more…)
Author Interviews, Brigham & Women's - Harvard, COVID -19 Coronavirus, NEJM, Vaccine Studies / 02.12.2021

MedicalResearch.com Interview with: Dr. Barbra Dickerman, PhD CAUSALab investigator and instructor Department of Epidemiology Harvard T.H. Chan School of Public Health  MedicalResearch.com: What is the background for this study? Response: Early randomized trials showed that the BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) vaccines were both remarkably effective at preventing symptomatic disease, when comparing each vaccine with no vaccine. However, head-to-head comparisons of these vaccines have been lacking, leaving open the question of which vaccine is more effective.  In this study, we analyzed the VA’s high-quality databases in a way that emulated the design of the hypothetical trial that would have answered this question. Specifically, we used the findings from the original trials to benchmark our methods and then extended them to provide novel evidence for the comparative effectiveness of these two vaccines in a real-world setting and across diverse subgroups and different time periods.

MedicalResearch.com Interview with: Holly Frost, MD Assistant Professor Pediatrics University of Colorado Anschutz School of Medicine Thersia Sebastian, MD Pediatrics, Denver Health  MedicalResearch.com: What is the background for this study? Response: Among children with acute otitis media (AOM) S.pneumoniae, H.influenzae, and M.catarrhalis are the predominant bacterial otopathogens. Historically, the gold standard for diagnosing otopathogens has been through middle ear fluid (MEF) culture. The challenge with MEF culture is that it is time-consuming and requires expert training often only done by specialists, thereby limiting its diagnostic utility to guide routine clinical care. Recent studies have shown that there is a high correlation between nasopharyngeal (NP) and MEF organisms during AOM. It is easier to collect NP swabs and less training is required. Thus, NP samples could serve as a surrogate for detection of otopathogens, potentially making identification of otopathogens practical and feasible in a typical practice environment compared to a MEF collection. Identification of otopathogens could be critical in treatment management of AOM, especially in the era of antimicrobial stewardship efforts to overall reduce unnecessary antibiotic use. Our goal was to compare the sensitivity and specificity of NP PCR to NP culture for common bacteria that cause ear infections.  (more…)

MedicalResearch.com Interview with: Kalyani Sonawane, PhD Assistant Professor of Management, Policy and Community Health UTHealth School of Public Health in Houston MedicalResearch.com: What is the background for this study? Response: Safety concern regarding the HPV vaccine is one of the most significant barriers to vaccination. Our objective was to determine how many US adolescents did not initiate the HPV vaccine during 2015-2018 because their parents had concerns regarding the vaccine’s safety. We also analyzed vaccine adverse event reporting data, in parallel, to understand if the public sentiment of HPV vaccine safety is in alignment with evidence from the vaccine safety surveillance system.  (more…)

MedicalResearch.com Interview with: Jeffrey M. Wilson MD Assistant Professor of Medicine Allergy and Immunology University of Virginia MedicalResearch.com: What is the background for this study? What are the main findings? Response: To date there have been few head-to-head studies evaluating the immune responses to COVID-19 vaccines. Here we measured IgG antibodies to the SARS-CoV-2 spike-RBD in adults who received full vaccination with either the Pfizer/BioNTech or Moderna vaccine. Our study is distinguished from many others because we developed a quantitative test with a read-out in standardized units (expressed as micrograms/mL). We found that antibody levels to the SARS-CoV-2 spike receptor-binding domain were lower in recipients of the Pfizer/BioNTech than Moderna vaccine. The difference in the antibody levels between vaccines was most evident in relatively older subjects. (more…)

Canaday, MD Associate Director of Research Geriatric Research, Education and Clinical Center (GRECC),  Cleveland VA Professor, Division of Infectious Disease, Case Western Reserve University Cleveland, Ohio MedicalResearch.com: What is the background for this study? Response: We were interested in following up on a prior study where we determined that nursing home residents, and in particular those that were given the Pfizer shot who never had COVID-19 in the past, had 4 fold less antibodies against the key Spike protein of the coronavirus than did the group of health care workers who were the other group studied. We wanted to see how those antibodies levels in these groups held up over 6 months.  (more…)

MedicalResearch.com Interview with: Kimberly G. Blumenthal, MD, MSc Massachusetts General Hospital The Mongan Institute Boston, MA 02114 Matthew S. Krantz, MD Division of Allergy, Pulmonary and Critical Care Medicine Department of Medicine, Vanderbilt University Medical Center, Nashville, Tennessee   MedicalResearch.com: What is the background for this study? Response: During the initial COVID-19 vaccine campaign with healthcare workers in December 2020, there was an unexpected higher than anticipated rate of immediate allergic reactions after Pfizer and Moderna mRNA vaccines.  This prompted both patient and provider concerns, particularly in those with underlying allergic histories, on the associated risks for immediate allergic reactions with the mRNA vaccines. Because of the significantly improved effectiveness of two doses of an mRNA vaccine compared to one dose, it was important to determine if those who experienced immediate allergic reaction symptoms after their first dose could go on to tolerate a second dose safely.    (more…)

Convener, Neurocritical care subsection Indian academy of Neurology  (IAN) MedicalResearch.com: What is the background for this study? Response:  Approximately 2-3 months after the vaccination programme commenced in India, we began to notice an uptick in the incidence of Guillain-Barré Syndrome (GBS) in our community. All the cases that presented to us during this period had almost the same clinical presentation. They presented within a few days ( usually within 1-2 weeks) of the first dose of the ChAdOx1-S/nCoV-19 vaccine. Most of the patients were women and it seemed to involve the middle aged to elderly age groups. As a result of this observation, we started to compile the clinical findings of these patients and collate them. (more…)

MedicalResearch.com Interview with: Michelle M. Chen, MD/MHS Clinical Lecturer Department of Otolaryngology-Head and Neck Surgery University of Michigan MedicalResearch.com: What is the background for this study? Response: HPV is the most common sexually transmitted infection in the United States and associated with several malignancies including oropharyngeal, cervical, vaginal, vulvar, penile, and anal cancers. In 2020, the FDA expanded the indications for HPV vaccination to include the prevention of oropharyngeal cancer, which is the most common HPV-associated malignancy and about 80% of oropharyngeal cancer patients are male. HPV vaccination rates are closely tracked for adolescents but less is known about vaccination rates for young adults. The goal of our study was to understand HPV vaccinations for young adult men and women, ages 18-21.  (more…)

MedicalResearch.com Interview with: Joel N. Blankson, MD, PhD Department of Infectious Diseases Associate Professor Cellular and Molecular Medicine Program Johns Hopkins MedicalResearch.com: What is the background for this study? Which vaccines did you evaluate? Response: Prior studies from several groups including our own have found T cell cross-recognition of peptides from SARS-CoV-2 and the common cold coronaviruses. We asked whether as a result of this cross-reactivity, immunization with the SARS-CoV-2 vaccine would also enhance T cell responses to the common cold coronaviruses. Prior studies also suggested that antibodies elicited from the mRNA vaccines had a reduced ability to neutralize the emerging variants of concern. Most of the study participants had received the Pfizer vaccine, but a few had received the Moderna vaccine.  (more…)

MedicalResearch.com Interview with: Michelle N. Meyer, PhD, JD Assistant Professor & Associate Director, Research Ethics, Center for Translational Bioethics & Health Care Policy Faculty Co-Director, Behavioral Insights Team, Steele Institute for Health Innovation Assistant Professor of Bioethics Geisinger Commonwealth School of Medicine Geisinger, PA MedicalResearch.com: What is the background for this study?   Response: Earlier research had found people are less likely to say they'll receive a COVID-19 vaccine offered to them under an Emergency Use Authorization (EUA) than one offered to them following full FDA approval. Earlier surveys had also found that only around 30% of health care workers intended to receive a COVID-19 vaccine. Because the public often looks to local health care workers for health advice, and in most prioritization schemes they were slated to be offered vaccines first, this was quite concerning for the prospect of achieving population immunity. Commenters had warned that if the FDA chose to make COVID-19 vaccines available under EUAs, that substantial efforts would need to be made to ensure trust. On Dec. 4, 2020, an announcement about anticipated vaccine availability was emailed to all 23,784 Geisinger employees, who were asked to indicate their intention to receive a vaccine when one was available to them and the reasons for any hesitation they might have.
