4%) was autoimmunized. Anti-Mia was the most common antibody (n = 14, 46.7%) among alloantibodies, followed by anti-E (n = 7, 23.3%). There was a significant association between pregnancy history with the development of antibodies whereas, no significant association was found between sociodemographic background, stage of CKD, hemodialysis status, underlying medical illness, and number of packed cell transfusions with the development of RBC antibodies.

One-eighth of our patient cohort had RBC alloimmunization, and the risk was increased in patients with a history of pregnancy. We propose Rhesus RBC phenotyping and to supply blood match Rhesus antigen in CKD patients, especially patients of reproductive age.

We sought to assess the prevalence of hepatitis B virus (HBV) seroprotection among vaccinated children in the Assiut governorate, Egypt, and assess a booster dose immune memory response among non-seroprotected children.

Using a multistage cluster sample, 566 children were recruited from three clusters one urban and two rural. Children were aged from nine months to 16 years old. All participants received the full three doses of the compulsory HBV vaccine during infancy. check details Serum hepatitis B surface antigen (HBsAg), total anti-hepatitis B core (anti-HBc) antibodies, and quantitative detection of anti-HBs were measured using enzyme-linked immunosorbent assay. Repeatedly positive samples for HBsAg/anti-HBc were submitted for quantitative HBV DNA detection using real-time polymerase chain reaction. Non-seroprotective participants (anti-HBs < 10 IU/L) were given a booster dose of HBV vaccine. Two weeks later, a blood sample was taken from each child to assess an anamnestic response.

The seroprotection rate ware-booster undetectable anti-HBs titers may be unable to develop anamnestic response, and a second vaccination series might be necessary for HBV protection for these children.
Older age of children was the only significant predictor for HBV non-seroprotection. High anamnestic response rate signifies the presence of immune memory with long-term protection despite the waning of anti-HBs over time. However, some children with pre-booster undetectable anti-HBs titers may be unable to develop anamnestic response, and a second vaccination series might be necessary for HBV protection for these children.Chikungunya virus (CHIKV), which causes a febrile illness characterized by severe and prolonged polyarthralgia/polyarthritis, is responsible for a global disease burden of millions of cases each year with autochthonous transmission in over 100 countries and territories worldwide. There is currently no approved treatment or vaccine for CHIKV. One live-attenuated vaccine (LAV) developed by the United States Army progressed to Phase II human clinical trials but was withdrawn when 8% of volunteers developed joint pain associated with vaccination. Attenuation of the Army's CHIKV LAV strain 181 clone 25 (CHIKV-181/25) relies on two mutations in the envelope 2 (E2) glycoprotein responsible for cell binding and entry, making it particularly prone to reversion, a common concern for replication-competent vaccines. High error rates associated with RNA virus replication have posed a challenge for LAV development where stable incorporation of attenuating elements is necessary for establishing safety in pre-clinical models. Herein, we incorporate two replicase mutations into CHIKV-181/25 which modulate CHIKV replication fidelity combined with additional attenuating features that cannot be eliminated by point mutation. The mutations were stably incorporated in the LAV and did not increase virulence in mice. Two fidelity-variant CHIKV LAVs generated neutralizing antibodies and were protective from CHIKV disease in adult mice. Unexpectedly, our fidelity-variant candidates were more mutable than CHIKV-181/25 and exhibited restricted replication in mice and Aedes mosquitoes, a possible consequence of hypermutation. Our data demonstrate safety and efficacy but highlight a further need to evaluate fidelity-altering phenotypes before use as a LAV given the potential for virulent reversion.The 'D614G' mutation (Aspartate-to-Glycine change at position 614) of the SARS-CoV-2 spike protein has been speculated to adversely affect the efficacy of most vaccines and countermeasures that target this glycoprotein, necessitating frequent vaccine matching. Virus neutralisation assays were performed using sera from ferrets which received two doses of the INO-4800 COVID-19 vaccine, and Australian virus isolates (VIC01, SA01 and VIC31) which either possess or lack this mutation but are otherwise comparable. Through this approach, supported by biomolecular modelling of this mutation and the commonly-associated P314L mutation in the RNA-dependent RNA polymerase, we have shown that there is no experimental evidence to support this speculation. We additionally demonstrate that the putative elastase cleavage site introduced by the D614G mutation is unlikely to be accessible to proteases.One-third of world's population is predicted to be infected with tuberculosis (TB). The resurgence of this deadly disease has been inflamed by comorbidity with human immunodeficiency virus (HIV). The risk of TB in people living with HIV (PLWH) is 15-22 times higher than people without HIV. Development of a single vaccine to combat both diseases is an ardent but tenable ambition. Studies have focused on the induction of specific humoral and cellular immune responses against HIV-1 following recombinant BCG (rBCG) expressing HIV-1 antigens. Recent advances in the TB vaccines led to the development of promising candidates such as MTBVAC, the BCG revaccination approach, H4IC31, H56IC31, M72/AS01 and more recently, intravenous (IV) BCG. Modification of these vaccine candidates against TB/HIV coinfection could reveal key correlates of protection in a representative animal model. This review discusses the (i) potential TB vaccine candidates that can be exploited for use as a dual vaccine against TB/HIV copandemic (ii) progress made in the realm of TB/HIV dual vaccine candidates in small animal model, NHP model, and human clinical trials (iii) the failures and promising targets for a successful vaccine strategy while delineating the correlates of vaccine-induced protection.
