s should seek to identify pro-equity strategies being implemented across additional countries, and to assess the extent to which these strategies have improved immunization coverage and equity.
Findings from this mapping can be useful in addressing equity gaps, reaching partially immunized, and 'zero-dose' vaccinated children, and valuable resource for countries planning to implement pro-equity strategies, especially as immunization stakeholders reimagine immunization delivery in light of COVID-19, and as Gavi finalizes its fifth organizational strategy. Future efforts should seek to identify pro-equity strategies being implemented across additional countries, and to assess the extent to which these strategies have improved immunization coverage and equity.Salmonella Enteritidis (SE) is a major cause of foodborne diseases in humans being frequently related to the consumption of poultry products. Therefore, guaranteeing early immunity to chicks is an important tool to prevent the colonization and infection by this pathogen. The present study evaluated the effectiveness of a candidate recombinant vaccine against SE. Thirty female and five male broiler breeders that were ten weeks-old were divided into 3 groups unvaccinated (UV), vaccinated with recombinant vaccine candidate (VAC) and vaccinated with commercial bacterin (BAC). Samples of serum and embryonated egg were collected at seven and twelve weeks after the booster dose to quantify the transfer rate of IgY to egg yolks and offspring. this website Subsequently, forty day-old offspring were divided into two groups (UV and VAC) and challenged on the following day with 107 CFU/chick of SE. Samples of serum, intestine, liver, and cecal content were harvested. Throughout the experiment period, significantly higher levels of IgY were observed in the egg yolk and also in the serum of broiler breeders and offspring of the VAC group in comparison to the UV group. In addition, increased transfer rates of IgY were observed in the VAC group when compared to the BAC group. Furthermore, higher villus-crypt ratios were found out in duodenum, jejunum and ileum at four days post-infection in the offspring from the VAC group. A high challenge dose of SE (107 CFU per chick) was used and despite the stronger humoral immune response provoked by the candidate vaccine, there were no statistical differences in the recovery of viable SE cells from the offspring cecal contents. Therefore, the effect of vaccination to improve intestinal quality may affect the development of the chickens and consequently increase the resistance to lower SE challenge doses.
Safe and effective vaccines against Coronavirus Disease 2019 (COVID-19) provide the best opportunity to control the pandemic. Having safe and efficacious vaccines available is only half the equation; people must also take them. We describe a study to identify COVID-19 vaccine attitudes, values and intentions immediately preceding authorization of COVID-19 vaccines in the US.

A national panel survey was conducted to measure intent to receive COVID-19 vaccines as well as disease and vaccine attitudes, values and trust in local, state and federal public health authorities.

Greater than 80% of respondents reported confidence they could adhere to COVID recommendations such as mask wearing, social distancing and hand washing. The majority of respondents (70%) reported believing that current drugs were somewhat or very good at treating COVID-19 infection. Vaccine intent fell into three groups Intenders (50%), Wait and Learn (40%), and Unlikelys (10%). Intent to get vaccinated was substantially lower among Afries; most others (40%) are uncertain. Levels of immunity associated with community protection will not be achieved without reaching those who are currently uncertain. Characterizing COVID-19 vaccine attitudes and intentions and ascertaining values and trust in local, state, and federal public health authorities that impact vaccine decision-making are essential.Rapid development of vaccines for COVID-19 has relied on the application of existing vaccine technologies. This work examines the maturity of ten technologies employed in candidate vaccines (as of July 2020) and NIH funding for published research on these technologies from 2000-2019. These technologies vary from established platforms, which have been used successfully in approved products, to emerging technologies with no prior clinical validation. A robust body of published research on vaccine technologies was supported by 16,358 fiscal years of NIH funding totaling $17.2 billion from 2000-2019. During this period, NIH funding for published vaccine research against specific pandemic threats such as coronavirus, Zika, Ebola, and dengue was not sustained. NIH funding contributed substantially to the advance of technologies available for rapid development of COVID-19 vaccines, suggesting the importance of sustained public sector funding for foundational technologies in the rapid response to emerging public health threats.Several vaccines have been used to control Marek's disease (MD) in chickens. However, the emergence of new strains of Marek's disease virus (MDV) imposes a threat to vaccine efficacy. Therefore, the current study was carried out to investigate whether concurrent administration of probiotics with the herpesvirus of turkeys (HVT) vaccine enhances its protective efficacy against MDV infection. In this regard, a cocktail comprised of four Lactobacillus species was administered with HVT to chicken embryos at embryonic day 18 (ED18) and/or from day 1 to day 4 post-hatch. The results revealed that the administration of a probiotic Lactobacillus with HVT at ED18 followed by oral gavage with the same lactobacilli cocktail to newly hatched chicks for the first 4 days post-hatch increased the expression of major histocompatibility complex (MHC) II on macrophages and B cells in spleen and decreased the number of CD4+CD25+ T regulatory cells in the spleen. Subsequently, chicks were infected with MDV. The chickens that received in ovo HVT and lactobacilli or HVT had higher expression of IFN-α at 21dpi in the spleen compared to the chickens that were challenged with MDV. Also, the expression of IFN-β in cecal tonsils at 10dpi was higher in the groups that received in ovo HVT and lactobacilli and oral lactobacilli compared to the group that received in ovo HVT alone. Moreover, the expression of tumor growth factor (TGF)-β4 at 4 days post-infection was reduced in the group that received both HVT and probiotics at ED18. Additionally, concurrent probiotics administration reduced tumor incidence by half when compared to HVT vaccine alone indicating enhancing effect of lactobacilli with HVT vaccine on host immune responses. In conclusion, these findings suggest the potential use of probiotic lactobacilli as adjuvants with the HVT vaccine against MDV infection in chickens.
