Table 1 Summary of main quantitative data on the evaluation of the effect of vaccines on the transmission of pig pathogens
From: The use of vaccines to control pathogen spread in pig populations
References | Number of publications | Main effect | Agreement between studies | Study category | Comments | |
|---|---|---|---|---|---|---|
Aujeszky’s disease | 9 | Significant reduction of transmission | Good for experimental studies | Experimental and observational studies | Field studies indicate potential limitations of experimental estimations | |
Classical swine fever | 8 | Significant reduction of transmission | Good | Experimental studies | Variability of results according to vaccines, administration route and the delay between vaccination and challenge | |
Mycoplasma Hyopneumoniae | 2 | No effect on transmission | Good | Experimental and field studies | ||
Actinobacillus Pleuropneumoniae | [33] | 1 | Decrease of infectiousness only | / | Experimental study | Separate evaluation of susceptibility and infectiousness |
PRRSv | 3 | Significant reduction of transmission | Good | Experimental studies | Good results with vaccine and challenge strains belonging to the same genotype | |
Influenza | [36] | 1 | Significant reduction of transmission | / | Experimental study | Significant reduction of transmission even with an heterologous strain |
PCV2 | [5] | 1 | Significant reduction of transmission | / | Experimental study | Evaluation with a challenge strain heterologous (2b) to the vaccine strain (2a) |
