We've barely made a dent in Adult and have focused on it for 5 years. While doing that, GSK has significantly grown Rotarix, Havrix, Engerix, and Pediarix. I'm not saying give up on adult but don't put all your time in adult. There was no good reason to become multi specialty in 2011. They could have left the folks alone calling on Pediatrics and the adult immunization professionals to call on primary care. When Merck tried to add to the adult portfolio by licensing agreements the products they picked up sucked or had bad AE (Afluria, Td).
The only good idea that leadership came up with was having reps call on Pharmacies too which is where most of the adult growth had been coming from. The idea that a primary care doctor is going to vaccinate like a pediatrician ain't going to happen anytime soon. You have to get that mindset change starting in the medical schools. Good luck with that.
Also during these 5 years we have had layoffs amongst Vaccine Customer Reps, CTL's (which I don't care), the initiation and elimination of the Pharmacy Vaccine Reps and the reduction of the National Adult Vaccine Account Managers. If they would have kept existing reps focused on Pediatrics and reps focused on Primary Care/Pharmacy, we wouldn't be having layoffs every 2 years. However, Merck wants to keep having layoffs because it helps the stock price. Merck also knows access is almost gone and big IDS groups don't want to deal with reps who can't do anything to lower prices or add any real value to an IDS group (handing out patient ed and offering immunization initiatives for a 2 to 3% discount doesn't cut it when Merck raises the prices by 7% or more) which is why all of these CTL's are grabbing these account manager positions. Get ready for more call centers phone reps, more contract reps and less full time door to door sales reps.
It gets harder each year to stay loyal to Merck because they continue to find ways to push folks out, especially those with the old pensions that really start to grow after 15 years. For those of us in that 15 year or up group, watch your back. We are dwindling.
