In this study, we investigated the antibody response in five-time intervals following the COVISHEILD first, second, and booster doses vaccination in previously infected and previously non-infected individuals. Methods: The study was a cross-sectional prospective study that took place at the Bangladesh Institute of Tropical and Infectious Diseases (BITID), Fouzderhat, Chittagong, in 46 individuals who received the COVISHEILD vaccine from February 2021 to January 2022. Blood samples were collected from vaccine recipients at five different time points (Baseline: Day 0 before 1st vaccine dose, 3 weeks, 2 months (before 2nd dose), 6 months, and 1 year after a booster dose) to measure the levels of S-RDB IgG antibodies using the EUROIMMUN Anti-S-Rose Disease Bioinfection assay test kits (Lübeck, Germany). Results: The study reveals that individuals with prior SARS-CoV-2 infection showed a significant increase in antibody levels after receiving the first vaccine dose, reaching 145.51 units at 3 weeks post-vaccination. This response remained stable at 117.6 units at 3 months and slightly declined to 103.26 units at 6 months, indicating a sustained immune response. For previously non-infected individuals, vaccination induced a strong immune response, with antibody levels of 159.62 units at 3 weeks, increasing to 150 units at 3 months, and then slightly declining to 87.84 units at 6 months. Despite the decline, antibody levels at 6 months and 1 year were notably higher than the pre-vaccination baseline of 0 units, indicating the development of a durable immune response following vaccination. In the <40 years age group, individuals with prior SARS-CoV-2 infection showed a substantial boost in antibody levels after receiving the first vaccine dose, reaching 198.61 units at 3 weeks post-vaccination. The response remained stable at 122.22 units at 3 months and declined to 73.7 units at 6 months, followed by a rise to 263.85 units at 1 year. Conclusion: Our findings highlight that tailoring vaccination approaches based on gender differences and considering vaccination in both previously and non-infected individuals will aid in optimizing immune responses and combatting the COVID-19 epidemic effectively.","PeriodicalId":330981,"journal":{"name":"Journal of Vaccines and Immunology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127741376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, tumors can thrive and avoid detection by the immune system, leading to the progression of the disease. Gaining a comprehensive understanding of these immune-related challenges is essential for the development of effective cancer treatments, including immunotherapies, which aim to enhance the immune response against cancer. In addition to conventional treatments, dietary interventions have shown potential in supporting cancer patients by improving their immune function through nutritional support, influencing the gut microbiome, boosting the immune system, and other means. It is crucial to note that these dietary interventions should be tailored to each individual cancer patient, considering their specific requirements, preferences, and tolerances. This review seeks to underscore the significance of implementing well-adapted and appropriate dietary approaches to enhance the anticancer immunity of cancer patients.","PeriodicalId":330981,"journal":{"name":"Journal of Vaccines and Immunology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123626416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Percutaneous closure is the most frequent management modality with excellent immediate and long-term results (two modes of closure: using coil or Occluder). The surgery remains reserved for complex anatomies or associated with other surgical congenital anomalies. Case presentation: We detail in this document the two methods of percutaneous closure step by step illustrated by pediatric cases. The first case concerns a 7 years old girl of 17 kg weight with a history of heart murmur that presented in the TTE a PDA estimated at 1mm with LV dilation. The second case concerns a 12 years old girl of 30 kg weight with also a history of heart murmur that presented on TTE a PDA of 4.5mm with LV dilation. Therapeutic intervention: In the first case, we perform a closure with coil 5/5 by a unique femoral arterial approach as a standardized attitude in our center avoiding additional venous access. For the second case, we opted for closure with prosthesis N° 6/8 by a double femoral approach (arterial and venous access). Outcomes: The follow-up was favorable for both patients, with total sealing of the defect immediately after the procedures that persist during the 6 months of control. Conclusion: The closure of PDA in children is a challenging procedure whose safety requires a good pre-and per-procedural evaluation allowing the right choice of the method and size of the closing device. The respect of the different closure stages and the critical per procedural ultrasound and angiographic control reduce the rate of complications making this technique accessible and safe. In our series of 108 PDA closures by Coil in children, the unique femoral arterial approach is the standardized attitude in the first line in all patients avoiding additional venous access, which allows the Coil release in the basic technique while the arterial access allows opacification and measurement of the channel. The unique arterial approach has reduced the risk of local complications at the puncture site and the duration of the procedure without difference in closure efficiency and embolization risk. In our series of 92 PDA closures by Occluder in children the double femoral approach is the standardized attitude for all patients, the venous access allows the device release while the arterial access allows opacification/ measurement of the channel and control device deployment.","PeriodicalId":330981,"journal":{"name":"Journal of Vaccines and Immunology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116605417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Feng, Yin Emily, Giwa Elizabeth","doi":"10.17352/jvi.000055","DOIUrl":"https://doi.org/10.17352/jvi.000055","url":null,"abstract":"Background: According to the Centers for Disease Control and Prevention (CDC), globally there is an estimated 200,000 cases of Yellow Fever Virus yearly, causing 30,000 deaths annually, with 90% of cases occurring in Africa. Where about 20% to 50% of people who get infected and develop severe symptoms from the yellow fever virus die. WHO report showed that Ghana was among 27 African countries with a high risk of yellow fever outbreak at any time. In response, there was a need to amplify the immunization campaign against yellow fever. Ghana in collaboration with WHO, GAVI, the Vaccine Alliance, and UNICEF began a sub-national campaign to vaccinate approximately 5.3 million people against yellow fever targeting people between ages 10 and 60 years from November 28 to December 4, 2018. 459 Adverse Events Following the Immunization (AEFI) in Ghana were reported from 28th November 2018 to 1st January 2019. The yellow fever vaccine is regarded as one of the safest, but with few adverse events. Therefore, there is a need to assess the severity of the reported adverse events following immunization in the 2018 sub-national yellow fever immunization program in Ghana. Objective: To study the Seriousness of adverse events following yellow fever vaccination in Ghana. Methodology: A retrospective review of AEFI data through a surveillance system during a Yellow Fever vaccination campaign in Ghana. The data comprised suspected 459 adverse events following the immunization (AEFI). The reported AEFI from 28th November 2018 to 1st January 2019 was used for this study as secondary data. A total of 5.3 million people were vaccinated. All vaccine recipients were between the ages of 10 years to 60 years. Data were analyzed using frequencies and descriptive statistics in STATA version 15. Findings and discussions: The study showed 459 (0.00086%) per 5.3 million recipients reported adverse events. The AEFI occurred mostly among females and persons aged 30-39 years. Out of the 459 recipients with adverse events, 432 (99.3%) recovered, and 3 (0.7%) died. The most common adverse event per region, sex, and age group is fever. The study also revealed AEFIs may have contributed to the death of 3 (0.000056%) per 5.3 million recipients. However, a causality assessment done by the Vaccine Safety Review Committee of independent experts showed no causality between the reported AEFI (deaths) and the YF vaccination. This indicates that the benefits of the vaccination outweigh the risk of adverse events or fatalities. Conclusion: In conclusion, it was found that the benefits of the Yellow Fever Vaccination (YFV 17D) outweigh the risk of adverse events or fatalities. Reported Adverse Events following the 2018 sub-national yellow fever vaccination per 5.3 million recipients were 459 representing 0.0086%. There was no causality between reported deaths 3 (0.000056%) and the YF immunization.

Thus, a booster dose was anticipated with hopes of inducing an immune response in formerly non-respondent individuals. We have vaccinated 394 patients with hematological cancer with the third dose of the mRNA BNT 162b2 COMIRNATY vaccine. Our results show promise, especially for increasing protective antibody levels in patients who retain valid antibody titers. We also identify problematic populations such as chronic lymphocytic leukemia, which still represent a major challenge for prophylaxis and protection against a severe course of COVID-19.

Depending on the signals received from different intrinsic or extrinsic factors, the macrophage polarity is determined. These cells are distributed in every tissue of the body and are also found as circulating cells in the bloodstream called ‘monocytes’. Natural products may be one extrinsic factor to modulate macrophage polarization. It is important to understand the mechanism by which natural products drive the polarization of macrophages. Based on recent advancements in the understanding of immunology, macrophages are classified as classically activated and alternatively activated, also designated as M1 and M2 macrophages respectively. The resident brain macrophages (microglia) get activated under stress and attain the M1 macrophage phenotype which is related to inflammatory mechanisms leading to neurodegeneration while treatment with plant-derived natural compounds drives the M1 microglia towards the M2 type which prevents the inflammatory response and protects the neurons. Understanding the mechanism of polarization of macrophages by natural compounds will be useful in treating different types of inflammatory diseases including Alzheimer’s and Parkinson’s. In this review, we summarized the current understanding of macrophage polarization using plant-derived natural compounds and their ability to regulate the pathophysiology of the tissues.","PeriodicalId":330981,"journal":{"name":"Journal of Vaccines and Immunology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130908219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
