*VAXXITEK® HVT + IBD is indicated to aid in the prevention of infectious bursal disease and Marek’s disease.
Reduction of disease may allow flocks to perform better across key production parameters. 1-4, 7-8

This document summarizes the field experience of using Vaxxitek HVT+IBD vaccine in broilers in Copacol Parana, Brazil over 6 months and 450 flocks totaling 7.2 million birds. The experimental group received a single dose of Vaxxitek HVT+IBD in ovo, while the standard program used Marek's disease vaccine in ovo and two intermediate IBD vaccines by drinking water. Results showed the Vaxxitek group had lower mortality, slightly better feed conversion ratio, older age, lower condemnation rates, and higher body weight compared to the standard program. Vaxxitek provides benefits of improved production performance and lower condemnation rates.

Merial EMEA

Oakland Farm Eggs Ltd. is the largest producer of colony eggs in the UK, rearing over 2 million pullets per year. They were experiencing problems with variable chick quality, poor flock uniformity, high Marek's disease challenge, and severe IBD infections causing 30% mortality. They administered 4 live hot IBD vaccinations but saw variable egg production. In 2010, they started vaccinating flocks with Vaxxitek HVT+IBD which improved overall bird health, achieved good uniform body weights, and allowed removal of the 4 on-farm live IBD vaccinations. Data from 2012 showed improved bodyweights, uniformity and laying performance since adopting the Vaxxitek vaccination.

This document discusses subclinical infections of porcine circovirus type 2 (PCVD). It notes that subclinical infections, which do not produce evident clinical signs, are much more common than clinical infections associated with the virus. The document explores ways to diagnose and measure the impact of subclinical PCVD infections, including through experimental infections, vaccination studies, and analyzing effects on mortality, average daily gain, and viral load in natural infections. While challenges exist, results consistently show that subclinical PCVD infections cause detrimental effects on pig production parameters that can be quantified through vaccination studies.

Merial EMEA

1) This case report describes a 120-sow farm in Japan that implemented PCV2 vaccination of sows in 2008 and saw a reduction in post-weaning mortality without vaccinating piglets. 2) After sow vaccination, the farm's post-weaning mortality rate decreased substantially from around 20% to an average of 5.2% in 2012, though it fluctuated due to other disease issues. 3) Testing showed that PCV2 viral loads decreased after sow vaccination such that the virus was not detected in pigs of any age three years after vaccination began. Continued sow vaccination provided strong immunity and global protection across the farm.

Chapat et al.-orf1 et orf2 cmi with CIRCOVAC vaccination in sows

Merial EMEA

This study assessed the cell-mediated immune response against PCV2 ORF1 and ORF2 proteins in pigs vaccinated with an inactivated PCV2 vaccine. The results showed that vaccination induced gamma interferon production against both ORF1 and ORF2, primed pigs for interleukin-2 secretion after challenge, and stimulated antibody responses. In contrast, unvaccinated pigs only developed immune responses after challenge. The cellular immune response detected is expected to contribute to reduced PCV2 replication in vaccinated pigs. This highlights the importance of including both ORF1 and ORF2 in PCV2 vaccine design.

Merial EMEA

This document reviews 9 publications that compare the efficacy of CIRCOVAC, an inactivated PCV2 vaccine, to 3 competitor vaccines in reducing mortality and improving average daily weight gain in piglets. The studies found that CIRCOVAC was at least as effective as the competitor vaccines in decreasing mortality rates from weaning to slaughter by 3.16-8.5% and increasing average daily weight gain by 633-800 grams per day. In conclusion, CIRCOVAC vaccination in piglets performed as well or better than other PCV2 vaccines in improving production parameters.

This study reviewed literature on the effects of vaccinating piglets against porcine circovirus type 2 (PCV2) with CIRCOVAC®. Mortality rates from weaning to slaughter were consistently lower in vaccinated piglets compared to unvaccinated piglets. A linear regression model found a strong correlation between the reduction in mortality after vaccination and the baseline mortality rate in unvaccinated pigs. The regression estimated a basic mortality rate of 4.57% and that vaccination can be expected to reduce mortality by 88% above this basic rate.

Laboratory testing found trypanosomes in the pigs' blood and confirmed the presence of Trypanosoma evansi via PCR testing. Treatment with diminazine aceturate and isometamidium chloride resulted in clinical improvement and reduced mortality. The outbreak was likely caused by transmission of T. evansi from cattle and buffalo in nearby palm oil plantations by tabanid flies present on the pig farm.

This study evaluated 4 commercial ELISA test kits for detecting antibodies to classical swine fever (CSF) by testing them on 6 standard serum samples. Test kit B detected antibodies in all samples, including those from pigs infected less than 21 days. Test kits S and I failed to detect antibodies in samples from pigs infected less than 21 days. The sensitivities of the test kits ranged from 60% to 100%. The performance of the test kits may depend on factors like the antigen used and the cut-off points designed for screening versus detection of true positives. More studies are needed to evaluate the test kits' ability to detect antibodies in pigs vaccinated for CSF.

This study evaluated the protective effects of two PCV2 vaccines (Vaccine A and Vaccine B) against fetal PCV2 infection in pigs. Gilts were vaccinated with one of the vaccines or unvaccinated as controls. After artificial insemination with PCV2-spiked semen, fetuses, placentas, and amniotic fluid were tested for PCV2. Vaccine A significantly reduced PCV2 positivity in fetuses compared to unvaccinated controls, but Vaccine B increased PCV2 positivity in placentas and amniotic fluid. The results suggest Vaccine A may better protect against subclinical fetal PCV2 infection than Vaccine B.

Merial EMEA

This document describes two trials that tested a delayed type hypersensitivity (DTH) test to detect compliance with PCV2 vaccination. In the first trial, vaccinated pigs all showed a significant skin reaction to antigen injection, while 50% of unvaccinated pigs reacted. The reaction was strongest 20-24 hours after injection. Histology confirmed a type IV DTH response. The second trial found nearly all pigs vaccinated with CIRCOVAC reacted, while only 25% of those vaccinated with another PCV2 vaccine reacted. The DTH test shows potential as a practical way to check compliance with CIRCOVAC vaccination. Further studies are needed to improve specificity and standardize the technique in field conditions.
