In the present study the effect of the locally produced genetic adjuvant of ginea pig specific CpG-motif-containing oligodeoxynucleotide (CpG-ODN) in an inactivated FMD virus vaccine was evaluated. Boosting the ginea pigs with FMD vaccine along with CpG-ODN adjuvant produced relatively higher ratio (5-fold) of FMDV-specific IgG2a / IgG1 than those vaccinated in the absence of CpG-ODN. The neutr...

newcastle disease (nd) is one of the most serious illnesses of chickens. live vaccines are widely used to prevent chicken from the disease all over the world. to access the effective and potentiate nd vaccine, a homogenous subpopulation from lasota strain was selected following cultivation of the virus on primary chicken embryofibroblast (cef) cells. pathogenicity indices and molecular characte...

Background: Bioinformatic approaches for designing vaccines have become a promising alternative to conventional methods. We herein designed a multi-epitope-based vaccine against colorectal cancer (CRC). Methods: Used peptides in the CRC vaccines were retrieved from databases of PubMed, Web of Science, Google Scholar, and Clinical trials. The adjuvants of Mycobacterial heparin-binding hemagglut...

A leading statistician has written to health secretary Matt Hancock urging him investigate the effects of extending gap between first and second dose Pfizer BioNTech covid-19 vaccine.1 Sheila Bird, former programme leader at Medical Research Council Biostatistics Unit University Cambridge a member Royal Statistical Society’s taskforce, said that while deviating from recommended dosing interval...

Novel efficient vaccines are needed to control tuberculosis (TB), a major cause of morbidity and mortality worldwide. Several TB vaccine candidates are currently in clinical and preclinical development. They fall into two categories, the one of candidates designed as a replacement of the Bacille Calmette Guérin (BCG) to be administered to infants and the one of sub-unit vaccines designed as boo...

The immune responses (serum anti-porcine epidemic diarrhea virus [PEDV] immunoglobulin G [IgG] and milk antiviral neutralizing antibodies) induced by various combinations of two PEDV immunization modalities (vaccine and oral immunization) were examined in unrelated swine production units in different locations. Anti-PEDV antibodies were undetectable in serum and milk of the control group (non-v...

There is no vaccine to prevent dengue fever, a mosquito-borne viral disease, caused by four serotypes of dengue viruses. In this study, which has been prompted by the emergence of dengue virus envelope domain III as a promising sub-unit vaccine candidate, we have examined the possibility of developing a chimeric bivalent antigen with the potential to elicit neutralizing antibodies against two s...

Recombinant, replication-competent rabies virus (RV) vaccine strain-based vectors were developed expressing HIV type I (HIV-1) envelope glycoprotein (gp160) from both a laboratory-adapted (CXCR4-tropic) and a primary (dual-tropic) HIV-1 isolate. An additional transcription stop/start unit within the RV genome was used to express HIV-1 gp160 in addition to the other RV proteins. The HIV-1 gp160 ...

This study was undertaken to audit staff varicella policy for UK paediatric centres, and to estimate the cost-effectiveness of implementing a staff varicella vaccine policy. A telephone survey of 22 hospitals was performed to determine the policy regarding varicella immune status among healthcare workers (HCWs). All hospitals surveyed except one recorded immune status of informed HCWs, and had ...

An analysis was undertaken to measure age-specific vaccine effectiveness (VE) of 2010/11 trivalent seasonal influenza vaccine (TIV) and monovalent 2009 pandemic influenza vaccine (PIV) administered in 2009/2010. The test-negative case-control study design was employed based on patients consulting primary care. Overall TIV effectiveness, adjusted for age and month, against confirmed influenza A(...
