Direct and crowding-out effects of a Hepatitis B vaccination campaign
Econ Hum Biol. 2023 Jul 23;51:101279. doi: 10.1016/j.ehb.2023.101279. Online ahead of print.ABSTRACTWe evaluate the direct and spillover causal effects of a Hepatitis B (HB) vaccination campaign in French schools on the vaccination adherence of the targeted pupils. Using a regression discontinuity design, we show that this campaign created an exogenous shock on vaccination behavior, increasing the HB vaccination rate for children aged 11 and above. At the same time, we show a drop in the measles, mumps, and rubella (MMR) vaccination rate of the targeted pupils and an increase in the parental belief that measles is a benign...

The Head of the Global Vaccine Group Gavi Is Resigning. Here ’s What He Learned During the Pandemic
The COVID-19 pandemic was a crucible for the public health world, and perhaps none were tested more than Gavi, the global nonprofit that makes vaccines its business. Faced with ensuring that the COVID-19 vaccines reached as many people in the developing world as possible, the organization created a new entity, COVAX, that served as the conduit for purchasing and distributing vaccines for the lowest-resource countries in the world.
Dr. Seth Berkley, who has headed the organization for years, is stepping down in August when his current term ends.
In a conversation with TIME, Berkley reflects on his tenure and what he, Gavi, ...

Is a ‘polyepidemic’ humanity’s next big threat? Childhood vaccine crusader shares concerns for future
By the start of 2011, the year epidemiologist Seth Berkley became CEO of Gavi, the Vaccine Alliance, the ambitious nonprofit had over its 11-year history supported the immunization of 288 million children in poor countries. But it also had a $3.7 billion funding gap between its plans and donor financial pledges. Making matters worse, an internal battle raged about how much it should invest in strengthening health systems versus more technological solutions, such as new or improved vaccines, favored by its main funder, the Bill & Melinda Gates Foundation. “It was a crisis,” Berkley says.
Berkley plans to step d...

Fight Aging! Newsletter, February 13th 2023
This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed.
The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

Vaccines based on the replication-deficient simian adenoviral vector ChAdOx1: Standardized template with key considerations for a risk/benefit assessment
Vaccine. 2022 Jun 14:S0264-410X(22)00755-1. doi: 10.1016/j.vaccine.2022.06.008. Online ahead of print.ABSTRACTReplication-deficient adenoviral vectors have been under investigation as a platform technology for vaccine development for several years and have recently been successfully deployed as an effective COVID-19 counter measure. A replication-deficient adenoviral vector based on the simian adenovirus type Y25 and named ChAdOx1 has been evaluated in several clinical trials since 2012. The Brighton Collaboration Benefit-Risk Assessment of VAccines by TechnolOgy (BRAVATO) was formed to evaluate the safety and other key fe...

Evaluation of Immune and Vaccine Competence in Steroid-Sensitive Nephrotic Syndrome Pediatric Patients
In conclusion, SSNS children at disease onset pre-immunosuppressive therapy showed a competent immune and vaccine response against tetanus and HBV, which can be correctly evaluated by quantification of antigen-specific memory B cells rather than by measuring serum IgG levels. This approach allows early identification of the impairment of immune and vaccine competence, which may derive from protracted use of different immunosuppressive drugs during disease course.

Data on the Prevalence of Liver Fibrosis in Middle Age
https://www.fightaging.org/archives/2020/11/data-on-the-prevalence-of-liver-fibrosis-in-middle-age/
Fibrosis is a consequence of age-related disarray in tissue maintenance processes, leading to the deposition of scar-like collagen that disrupts tissue structure and function. It is an ultimately fatal issue for which there are only poor treatment options a...

Viruses, Vol. 11, Pages 627: Identification, Pathogenicity of Novel Fowl Adenovirus Serotype 4 SDJN0105 in Shandong, China and Immunoprotective Evaluation of the Newly Developed Inactivated Oil-emulsion FAdV-4 Vaccine
In this study, we isolated a novel FAdV-4 strain SDJN0105 from a broiler farm with HHS disease in Shandong Province. Pathogenicity was evaluated by the observation of clinical symptoms, necropsy changes, and pathological tissue sections after oral and intramuscular (IM) infection of Specific pathogen free (SPF) chickens. The chickens infected by IM injection all died within three days, and chickens infected via the oculonasal route died within five days post-infection (dpi). Histopathological examination revealed that the pathology was confined to heart, liver, spleen, lung, kidney, and particularly the liver. Irrespective...

Household transmission and disease transmissibility of a large HAV outbreak in Lazio, Italy, 2016–2017
Publication date: Available online 13 June 2019Source: EpidemicsAuthor(s): Giorgio GuzzettaAbstractA major outbreak of Hepatitis A Virus (HAV) has swept through Europe between mid-2016 and 2017, mainly within the community of men who have sex with men (MSM). Over the same period, about 1,000 outbreak-related cases of acute Hepatitis A (AHA) were recorded in Lazio region, Italy.We calibrated a Bayesian model to reconstruct likely transmission events within all 44 households where multiple infections were recorded, representing a total of 103 cases from the HAV outbreak in Lazio. Based on information on the observed times of...
