Abbott's Ross the best marketing machine in the pediatric field. They are a leader in infant formula. And they have the most successful pediatric product: Survanta for premature newborns respiratory distress syndrome. "Small incidence of paralysis" not with any of the DTP vaccines, not even the old whole cell, maybe they are talking about the Hypotonia-hyporesponsive episodes clearly a complication of the old whole cell vaccines, less with the current DTaPs and none so far with Certiva. This is a clear advantage to Certiva. Every pediatrician nightmare is a vaccine side-effect of this kind. Forget the "small incidence". For example, with the oral polio vaccine the incidence of permanent paralysis is 1 in 700,000 for the first dose. The debate ended with the use of the enhanced intramuscular (IPV)vaccine for the first two doses. When it comes to normal infants becoming affected by a vaccine the dominant view is that small is not sufficient, due to the almost compulsory nature of vaccine programs. The use of combination vaccines is a temporary disadvantage for NVX, in the last two doses of the regimen, this is compared to DTaP-HIB combination. But the DTaP-IPV from NVX already in Europe (at least in Denmark) could lesser the disadvantage. Especially, that the combination DTaP-HIB is so far proven very poor responses in less than 6 month/old infants. If DTaP-IPV proves itself a better immune stimulator, then NVX could win the battle. They do have the chance, since HIB is a very complex product, IPV is less so and give better response than HIB on its own. Here NVX has a good fighting chance. Both DTaP-HIB and DTaP-IPv could be use to decrease one shot to the infants at the same schedule of 2 and 4 mo of age. Certiva is recommended for 3 mo, 5 mo, 1 year in Sweden, this avoid the 6mo old DTaP. It could be an advantage or not. This is a point that Sturza stresses, but NVX has a fighting chance. Sturza claims that the effectiveness of Certiva is 71% vs the competitors 80% to 85%. This is easily dismiss, first compared to the old whole cell vaccines 50% to 60% in the best preparations (some were cero %, could you believe it? but real truth) it is very good. 2nd the difference with the current DTaPs is not relevant. 3rd the Sweden-Danish experience is top rate quality, so clinically and epidemiologically Sturza's efficacy argument is moot. Recently, Abbott got a supplier agreement with Columbia Health Care, the biggest and richest hospital chain in America, I am sure Certiva will be market to this private provider. Columbia do not have the same strength in the outpatient clinics markets, but it is introducing itself as their avenue of expansion. The market value of NVX is hefty. But accumulation is clearly ongoing. I am still not a long, not a short.
