Respiratory Vaccines

I've switched modified live respiratory vaccines this year on my feeder calves. I'm having more sickness than usual. Just wondering what others have seen for comparisons and good or bad experiences. Thanks

I assume you mean switched to modified live and not just changed ML brands.
Could you provide more information?

Purchased or home raised calves? Age at vaccination? Vaccinate 2-3 weeks before anticipated stress.
Buying calves and vaccinating day of arrival when they are already stressed is not recommended and in my opinion
might be increasing your rate of shipping fever.
