Vaccine Development Insights

Early efforts in vaccine development for reducing methane emissions from livestock are underway, particularly in New Zealand and the US. The challenge lies in the rumen's unique immune system, which requires innovative delivery methods for antibodies. Initial studies suggest that vaccinating mother cows could significantly lower methane emissions in their offspring by altering the rumen's microbial environment from an early age. Efficacy rates are still being evaluated, with hopes for improvements beyond 20%.
