With the difficulty in access to PPSV23 as the new pneumonia vaccine is now standard (non polysaccharide vaccine), have you used MPSV4 (meningococcal) vaccine for evaluation of response to polysaccharide vaccine?
Have you used this for adults, children, or both?
Answer from: at Academic Institution
No, but there is good data on using Typhim Vi vaccine, which is also polysaccharide and MCW has a good lab to evaluation for polysaccharide vaccine response.
