Cryptosporidiosis is caused by the C. parvum protozoa and can result in lethargy and poor growth rates in neonatal ruminants, in addition to long periods of persistent diarrhea. Medgene’s cryptosporidiosis vaccine can be given to cows and heifers prior to calving, providing protection to calves through their colostrum. It is also the only crypto vaccine for cattle in the U.S. and is expected to be available this month.
