| Protocol | Test | Average Age of Waning of Anti-JEV Maternal Antibodies | Country | Reference |
|---|---|---|---|---|
| 80 piglets, 2–7 months old, from farms, bled monthly | HIA | >4 months old | Japan | [47] |
| 9 piglets, in mosquito traps, bled monthly | HIA | >1.5 months old | Japan | [47] |
| 2 cohorts of 15 piglets, 2 months old, bled every 10 days for 4 months | IgG ELISA | >3 months old | Cambodia, peri-urban | [74] |
