Has the pneumococcal vax changed in the past years?
I was wondering if prevnar has changed in the past couple years. I adjust my kids schedules as the years go on and the technology changes. I remember with my last babies born in 2008 & 2009, prevnar wasn't considered the safest vaccine and at that time it protected against something like 7 out of 100 strains. Has the vaccine gotten better with safety and side effects? Does it protect against more strains now?
