Bioluminescence imaging (BLI) was used to follow dissemination of recombinant vaccinia virus (VACV) expressing luciferase (IHD-J-Luc) in BALB/c nu/nu mice treated post-challenge with monoclonal antibodies (MAbs) against L1 and B5 VACV proteins in a model of Progressive Vaccinia (PV). Areas Under the flux Curve (AUC) were calculated for viral loads in multiple organs in individual mice. Following scarification with 10 pfu, IHD-J-Luc VACV undergoes fast replication at the injection site and disseminates rapidly to the inguinal lymph nodes followed by spleen, liver, and axillary lymph nodes within 2-3 days and before primary lesions are visible at the site of scarification.

Post-vaccinial non-viral folliculitis has been recognized in the past decade as a new adverse cutaneous reaction to smallpox vaccination. Contrary to more serious smallpox vaccine reactions, post-vaccinial non-viral folliculitis has a benign course and resolves spontaneously within approximately 7 days. We describe additional histopathologic findings associated with post-vaccinial non-viral folliculitis, which has only been described once previously.

Objective: To evaluate the safety and efficacy of a human adenovirus-5 vaccine for protecting weaned pigs against swine influenza virus subtype H3N2 infection when administered via 2 injection methods.
Animals: 76 pigs.
Procedure: 6 groups of weaned pigs received a 10-fold serial dilution of recombinant adenovirus expressing H3 hemagglutinin and a constant amount of recombinant adenovirus expressing nucleoprotein, either via a needle-free injection device or by traditional IM injection.

Background: Numerous literature reports describe clinical efficacy of intramuscular vaccinia immune globulin (VIG) for complications of smallpox vaccination, prophylaxis of individuals with contraindications to vaccination, and prevention of smallpox among close contacts of patients with smallpox.
Methods: We reviewed the literature regarding VIG treatment and prophylaxis of smallpox vaccine complications and the use of VIG as a preventative measure for close contacts of patients with smallpox.
Results: Data regarding intramuscular administration of VIG for treatment of smallpox vaccine complications occurred in 16 articles, none of which reported formal controlled trials.
