Wilson MD Assistant Professor of Medicine Allergy and Immunology University of Virginia Dr. Wilson[/caption] 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.

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.

What are the main findings? Response: Military clinicians, especially those in the Defense Health Agency Immunization Healthcare Division, first became aware of a few cases of myocarditis following COVID-19 vaccination in early Feb 2021.  These cases included young men who presented with chest pain a few days after 2nd dose of mRNA (Pfizer or Moderna) vaccine.  As more young people became eligible for 2nd doses of vaccine, more cases were identified.  By late April, the military had identified 23 cases of myocarditis, with remarkably similar presentations, after COVID-19 vaccination.  This case series is described in the current issue of JAMA Cardiology.

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.

MedicalResearch.com Interview with: Isaac See, MD Centers for Disease Control and Prevention COVID-19 Response Team Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: On February 27, 2021 the U.S. Food and Drug Administration (FDA) granted emergency use authorization for the Janssen/Johnson & Johnson (J&J) COVID-19 Vaccine in people 18 years of age or older in the United States.  The Janssen/J&J COVID-19 Vaccine uses a replication-deficient (i.e., cannot cause infections) human adenovirus vector.  In mid-March, the European Medicines Agency announced that they had conducted a preliminary investigation of cases of blood clots and low counts of blood cells called platelets in patients who had recently received the Oxford/AstraZeneca COVID-19 Vaccine, which uses a replication-deficient chimpanzee adenovirus vector.  This syndrome of blood clots and low platelet counts has been called thrombosis with thrombocytopenia syndrome, or TTS.  The European investigation showed that over 70% of their cases specifically involved blood clots in particular veins inside the brain, a condition caused cerebral venous sinus thrombosis (CVST), in addition to low platelet counts (thrombocytopenia is the medical term for low platelet counts). CVST is already a rare condition, and CVST with thrombocytopenia is even rarer.  By April 12, 2021, approximately 7 million doses of the Janssen/J&J COVID-19 Vaccine had been given in the United States, and six cases of CVST and thrombocytopenia after receipt of the Janssen/J&J COVID-19 Vaccine had been reported to the U.S. Vaccine Adverse Event Reporting System (VAERS), which is the U.S. national vaccine safety monitoring system.  The next day (April 13, 2021) CDC and FDA recommended a pause in use of the vaccine recommended to allow for further investigation of these events.  On April 23, 2021 data about the first 12 cases reported after authorization of the Janssen/J&J COVID-19 Vaccine were presented at an emergency meeting of the Advisory Committee on Immunization Practices (ACIP) to decide what to recommend regarding the Janssen COVID-19 vaccine.  The ACIP concluded that the benefits of resuming Janssen COVID-19 vaccination among persons aged 18 years or older outweighed the risks and reaffirmed its interim recommendation under the FDA’s Emergency Use Authorization.  The FDA’s Emergency Use Authorization includes a new warning for rare clotting events among women aged 18 to 49 years. Our report provides clinical details about these first reported 12 U.S. cases of CVST and thrombocytopenia following receipt of the Janssen COVID-19 Vaccine.

MedicalResearch.com Interview with: Laura M. Bogart, PhD Senior Behavioral Scientist RAND Corporation Santa Monica, CA 90407-2138 MedicalResearch.com: What is the background for this study? Response: Recent media polls continue to show that Black Americans are less likely to intend to get the COVID-19 vaccine than White Americans, and initial state data show a similar racial/ethnic disparity in vaccination rates. Initial uptake of the vaccine has been significantly affected by inequities in vaccine access and supply. In addition to these challenges, other factors contribute to hesitancy around vaccination, including self-perceived risk of infection, trust in the vaccine itself, trust in healthcare systems, healthcare providers, and policymakers who support the vaccine, and trust in the pharmaceutical industry and clinical research. In this study, we conducted a survey of a nationally representative sample of 207 Black Americans in late 2020, after initial COVID-19 vaccine effectiveness and safety data were released to the public. We also did in-depth interviews with a subsample of those surveyed who said that they would not get vaccinated. In addition, we engaged with a stakeholder advisory committee comprised of individuals who represent different subgroups and organizations in Black communities in the U.S., in order to discuss the results and make recommendations for policies to increase COVID-19 vaccination among Black Americans.

Response: When a safe and effective vaccine for COVID-19 reaches the market, the world will not change overnight.  Rather, government and public health individuals will have to develop a comprehensive plan to distribute the vaccine and to convince potentially wary Americans to take it. Our study examined the influence of both specific vaccine characteristics and the politics surrounding it on public willingness to vaccinate.  Both matter in important ways.  For example, efficacy is unsurprisingly a major driver of public opinion; Americans are more willing to take a vaccine that is more efficacious.

Response: Anal cancer is one of the six human papillomavirus associated cancers.  Rates of anal cancer are increasing in the US, but no prior study quantified the contemporary trends (i.e., increase in rates over time) in anal cancer incidence. It was unknown whether the rise is real or driven by increased screening in some high-risk populations. Incidence trends according to age and stage at diagnosis was also never comprehensively studied. Furthermore, it was unknown whether the rise in incidence has led to a rise in mortality. Our objective was to answer these questions.

MedicalResearch.com Interview with: Naomi E Aronson, MD, FIDA, FACP Professor and Director, Infectious Diseases Division Uniformed Services University of the Health Sciences Bethesda, MD  MedicalResearch.com: What is the background for this study? Response: BCG is a live attenuated mycobacteria vaccine used to prevent tuberculosis which has been reported to have associated nonspecific effects such as treatment of diabetes, bladder cancer, prevention of severe respiratory infections in children, and suppressed autoimmune responses. In earlier reports in the 1970s, results of epidemiologic studies were divided as to whether BCG vaccine was associated with subsequent rates of malignancy, specifically leukemia (protective) and non Hodgkins lymphoma (higher rates). To further evaluate these observations we studied cancer data collected in the 60 year follow up of a controlled trial of BCG in American Indian/ Alaska Native schoolchildren.

MedicalResearch.com Interview with: Ms. Cassandra Pingali Ms. Pingali worked on this paper while a a graduate student at Emory University, and completed it post-graduation. She is currently an ORISE fellow at Centers for Disease Control and Prevention Immunization Services Division MedicalResearch.com: What is the background for this study? Response: Despite high overall immunization coverage in the United States, we are currently experiencing the largest measles outbreak since measles was declared eliminated in 2000. In 2014, California grappled with a very large measles outbreak known as the “Disneyland” outbreak. Later investigation revealed that most of the affected children were unvaccinated against measles despite the availability of a safe and effective vaccine. In order to prevent future outbreaks, California officials wanted to improve their declining childhood vaccination coverage. California passed two laws and implemented an educational program for school staff to increase vaccination rates in the state. We felt it was important to take a systematic look at these interventions and examine if public health initiatives such as these are working to improve vaccination rates.

MedicalResearch.com Interview with: “Syringe and Vaccine” by NIAID is licensed under CC BY 2.0Ali Moghtaderi PhD MBA Assistant Research Professor and Avi Dor PhD Professor of Health Policy and Economics Milken Institute School of Public Health George Washington University MedicalResearch.com: What is the background for this study? Response: In this study, we investigate the effect of Human Papillomavirus (HPV) vaccination on participation in Pap test, which is one of the most effective cancer screening interventions. Cervical cancers are causally linked to HPV infections. The Pap test is a diagnostic procedure for early detection of cervical cancer. HPV vaccination provides partial protection against cervical cancer, and the Pap test is strongly recommended for women 21 to 65 years of age even after vaccination. If vaccination leads to a reduction in testing participation, it could contribute to greater incidence and severity of cervical cancer. Note that we focus on relatively older women (age 22 or older) who were not vaccinated at younger ages.

MedicalResearch.com Interview with: [caption id="attachment_45486" align="alignleft" width="80"]Anna Beavis, MD, MPH Assistant Professor The Kelly Gynecologic Oncology Service Department of Gynecology and Obstetrics Johns Hopkins Medicine Baltimore, MD 21287-128 Dr. Beavis[/caption] Anna Beavis, MD, MPH Assistant Professor The Kelly Gynecologic Oncology Service Department of Gynecology and Obstetrics Johns Hopkins Medicine Baltimore, MD 21287-128 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to look at reasons parents don’t vaccinate their children against HPV, including how those reasons have changed over time from 2010-2016 and how those reasons are different between boys and girls in the most recent data from 2016. We used a nationwide dataset which is publically available from the CDC (Centers for Disease Control) – the National Immunization Survey-Teen, or NIS-Teen - which surveys parents of teens ages 13-17 years old every year to determine rates of all recommended vaccinations. In parents who report that they don’t intend to vaccinate their child against HPV , the survey asks parents why. We found that from 2010 to 2016, the percentage of parents reporting concerns about their child not being sexually active yet went down significantly for both boys and girls. Also, in boys specifically, parents reported male gender as a less common reason for not vaccinating. For both boys and girls, we found that concerns about safety and side effects, necessity, and lack of knowledge about the vaccine were common reasons for not planning to vaccinate.  Also, 10% of parents of girls vs. 20% of parents of boys reporting never having a provider recommendation for the vaccine as their primary reason for not vaccinating. These results may reflect the growing public understanding of the HPV vaccine as a vaccine which is best given before exposure, so before initiation of sexual activity between the ages of 11 and 12, and that it is recommended for both boys and girls. Also, over 80% of people will have an HPV infection in their lifetime, so everyone should get vaccinated regardless of anticipated sexual activity. Additionally, providers should focus their counseling and recommendation on improving knowledge about the HPV vaccine, including its decade-long track record of safety and necessity.

MedicalResearch.com Interview with: "Vacuna influenza / Flu vaccine" by El Alvi is licensed under CC BY 2.0Kathryn M. Edwards, M.D. Sarah H. Sell and Cornelius Vanderbilt Chair in Pediatrics Professor of Pediatrics Vanderbilt University School of Medicine Dr. Edwards discusses the statement from the Infectious Diseases Society of America (IDSA) regarding the Centers for Disease Control and Prevention’s new data on child vaccine rates across the United States. MedicalResearch.com: What is the background for this study? What are the main findings? Response: To monitor the uptake of vaccines the CDC conducts a National Immunization Survey each year.  This survey is conducted by random-digit dialing (cell phones or landlines) of parents and guardians of children 19-35 months of age.  The interviewers ask the families who provides the vaccines for their children and if these providers can be contacted to inquire about the immunizations received.  The overall response rate to the telephone survey was 26% and immunization records were provided on 54% of the children where permission was granted.  Overall 15, 333 children had their immunization records reviewed. When comparing immunization rates for 2017 and 2016, the last two years of the study, several new findings were discovered. First the overall coverage rate for 3 doses of polio vaccine, one dose of MMR, 3 doses of Hepatitis b, and 1 dose of chickenpox vaccine was 90%, a high rate of coverage.  Children were less likely to be up to date on the hepatitis A vaccine (70%) and rotavirus vaccine (73%). Coverage was lower for children living in rural areas when compared with urban areas and children living in rural areas had higher percentages of no vaccine receipt at all (1.9%) compared with those living in urban areas (1%). There were more uninsured children in 2017 at 2.8% and these children had lower immunization rates.  In fact 7.1% of the children with no insurance were totally unimmunized when compared with 0.8% unimmunized in those with private insurance. Vaccine coverage varies by state and by vaccine.

Response: The 2 Phase 1 trials were randomized, double-blind, placebo-controlled, multi-center studies evaluating the safety, tolerability, and relevant bioactivity of Nexvax2 in HLA-DQ2.5+ patients with celiac disease. In one study, patients received three fixed doses of Nexvax2 or placebo once per week over a three-week period. In the other study, patients received 16 fixed doses of Nexvax2 or placebo twice per week over an eight-week period. Both studies evaluated a range of fixed, intradermal dose administrations in a series of ascending dose cohorts, which included a crossover, double-blind, placebo-controlled oral gluten challenge in the screening and post-treatment periods. The primary outcome measures were the number and percentage of adverse events in the treatment period.

Dr.  Mubdiul Ali Imtiaz[/caption] MedicalResearch.com Interview with: Mubdiul Ali Imtiaz, MD Department of Internal Medicine Rutgers University, New Jersey Medical School Newark, NJ 07103 Medical Research: What is the background for this study? Response: Resident physicians (RPs) were defined to be all individuals enrolled in a graduate medical education training program in a healthcare setting. There were 611 resident physicians enrolled in 47 post-graduate residency and fellowship programs at RU-NJMS during the 2013-2014 academic year. Influenza immunization was strongly recommended, but not mandatory for Resident physicians during 2013-2014. A link to the online survey using a standardized, anonymous, self-administered questionnaire was emailed by the program-chiefs to their respective RPs to collect demographic characteristics, influenza immunization status during the 2013-2014 and the previous season, and reasons for non-vaccination. Medical Research: What are the main findings? Response: The overall self-reported immunization rate of  Resident physicians in 2013-2014 was 76.7%. The immunization rate did not differ by the location of medical school attended (P= 0.55) or sex (P= 0.69). Among the respondents, 95.8% had influenza vaccination in the past and 83.1% received influenza vaccine during 2012-2013 flu season. History of influenza vaccination ever and in 2012-2013 were both significantly associated with receiving the vaccine during the 2013-2014 season (P<0.01 for both). The most common reason for not being vaccinated (38.6%) was “lack of time to get immunized” (see Figure 1). The most common cited motivating factors to be vaccinated during the next influenza season among the NVRPs were “making vaccinations in the workplace at convenient locations and times” (43.2%), “availability of mobile flu vaccination carts in hospital floors” (40.9%), and “establishing mandatory flu vaccination for employment” (36.4%).

Robert B Belshe, MD Division of Infectious Diseases, Allergy & Immunology Saint Louis University School of MedicineMedicalResearch.com Interview with: Robert B Belshe, MD  Division of Infectious Diseases, Allergy & Immunology Saint Louis University School of Medicine   Medical Research: What are the main findings of the study? Response: A vaccine that protects against an old strain of avian flu primes the immune system to mount a rapid response when a vaccine designed to protect against a related but different and new strain of avian flu is given a year later, according to Saint Louis University research findings reported in JAMA. In addition, when combined with an adjuvant, which is a chemical that stimulates the immune system to produce more antibodies, a lower dose of the new avian flu vaccine worked better in triggering an immune response than a stronger dose without adjuvant. That means the amount of vaccine against a new strain of bird flu can be stretched to protect more people if an adjuvant is added. Both findings represent important strategies researchers can continue to study to fight new strains of bird flu that people previously have not been exposed to, and consequently can rapidly turn into a pandemic outbreak and public health emergency, said Robert Belshe, M.D., professor of infectious diseases, allergy and immunology at Saint Louis University and the lead author of the article, which appeared in the Oct. 8, 2014 issue of JAMA.

Greenberg, M.D. Vice President, Scientific & Medical Affairs, and Chief Medical Officer Sanofi Pasteur US.   Medical Research: What are the main findings of the study? Dr. Greenberg: The New England Journal of Medicine published positive results from a randomized, double-blind, large-scale, multi-center efficacy trial, which found that Fluzone® High-Dose (Influenza Vaccine) was more efficacious in preventing influenza illness (“the flu”) in adults 65 years of age and older compared to standard-dose Fluzone vaccine. Fluzone High-Dose vaccine was found to be 24.2 percent (95% CI, 9.7 to 36.5) more effective in preventing influenza relative to standard-dose Fluzone vaccine for the primary endpoint (laboratory-confirmed influenza associated with typical clinical symptoms occurring at least 14 days post-vaccination caused by any viral type or subtype). In other words, investigators determined that participants in the Fluzone High-Dose vaccine group were less likely to get the flu than those in the standard-dose Fluzone vaccine group. The study safety data were consistent with previous Fluzone High-Dose vaccine studies.

Dingell VA Medical Center Associate Dean for Veterans Affairs & Professor of Surgery Wayne State University School of Medicine John D. Dingell VA Medical Center Chief of Staff Detroit, MI 48201 MedicalResearch: What are the main findings of the study? Dr. Gruber: We successfully addressed the problem of inadequate intracellular delivery of tumor- specific antigens (TSAs) to dendritic cells (DCs) by using synthetic cell-penetrating domains or peptides (CPPs) to create fusion tumor antigens (Ags) that readily penetrate through the plasma membrane. We demonstrated cloning and purification of the TSA melanoma-associated antigen 3 (MAGE-A3) in frame with CPP, producing enhanced cytosolic bioavailability in dendritic cells without altering cell functionality. Further, we showed that recombinant bacterial proteins can be easily engineered to purify large amounts of CPP-MAGE-A3. Use of full-length proteins circumvents the need to define HLA class I allele binding before vaccination and increases the number of epitopes recognized by CD8+ cytotoxic T lymphocytes (CTLs) when compared with peptide-pulsed dendritic cells. Finally, the use of proteins rather than plasmids or viral vectors for in vitro dendritic cell vaccine preparation avoids the practical and theoretical safety concerns regarding genomic modification.

Dr. Munoz: 1. Tdap vaccine was safe and well tolerated during pregnancy 2. Women who are pregnant have adequate responses to the Tdap vaccine, similar to those of women who are not pregnant. 3. Antibodies to pertussis are efficiently transferred to the fetus through the placenta so that babies of mothers who were vaccinated during pregnancy had significantly higher concentrations of antibody at birth and up to 2 months of age, when compared to infants of mothers who were vaccinated post-partum. 4. Higher antibody concentrations in the first two months of life are likely to provide protection against pertussis during this period of high vulnerability 5. Infants of mothers who were vaccinated during pregnancy had adequate responses to their routine pertussis vaccines at 2, 4, and 6 months of age, and had expected and adequate responses to their 4th dose of vaccine at 1 year of age. The absolute concentration of antibodies to some of the pertussis antigens might be modestly lower after the primary series of vaccines in some infants of mothers who were vaccinated during pregnancy, but this difference does not persist after the 4th dose.
