|---|---|---|---|---|---|---|
| Aujeszky’s disease | [6, 7, 11, 12, 15, 21–24] | 9 | Significant reduction of transmission | Good for experimental studies | Experimental and observational studies | Field studies indicate potential limitations of experimental estimations |
| Classical swine fever | [10, 16, 25–30] | 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 | [31, 32] | 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 | [17, 34, 35] | 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) |
