In the title of the article, the word “Vaccination” should be “Immunization.” The correct title is: Economic Analysis of Immunization Strategies for PRRS Control. The correct citation is: Linhares DCL, Johnson C, Morrison RB (2015) Economic Analysis of Immunization Strategies for PRRS Control. PLoS ONE 10(12): e0144265. doi:10.1371/journal.pone.0144265

There is an error in the seventh sentence of the Abstract. The correct sentence is: Preventive vaccination of sow herds was beneficial when the frequency of PRRSv infection was at least every 1 year and 9 months.

There are errors in Figs 3–5. Please see the corrected Figs 3–5 below.

(A). Effect of attenuated-PRRSv impact on pig growth performance on break-even of preventative vaccination, considering sow herd-level impact of 1 PSY. (B) Effect of attenuated-PRRSv impact on reduction of pigs weaned/sow/year on break-even of preventative vaccination, assuming no impact of attenuated PRRSv on growth performance.

(A) Impact of margin over variable cost (MOVC) and production cost attributable to PRRSv on advantage to have prior PRRSv-immunity. (B) Impact of MOVC and PSY on advantage to have prior PRRSv-immunity.
