What a waste of everyone's time. The Sci-Am article is subtitled "The shortcomings of the whooping cough vaccine may help explain the disease's resurgence." That says it all. Pertussis vaccines have always been problematical. What you are saying is that because you've had problems with a Yugo you'll not drive a Toyota.
The NVIC and Barbara Loe Fisher are hardly dependable sources, they're nutcases.
The articular by Hsieh YC, et al. in Vaccine. 2014 summarizes by stating, "Clinical significance of higher shedding viral loads in RV2 should be further observed." I don't know what point you were trying to make but the study does not seem to support any of your claims since it has been shown that the shedding of virus by recently vaccinated people is rarely causes complications in the vaccinated person and that vaccine strain viral shedding rarely causes disease in close contacts of the recently vaccinated. Can it cause problems? Maybe, rarely, in few cases. The anti-vaccine paranoids are big on weasel words especially, "may"and "can" as in, "you may be killed in a traffic accident on your way to the doctor," or "a fall can break a bone." They are spouting base canards of the first order.
Here are the only two mentions of shedding in the CDC article:
Sporadic nosocomial cases of mumps have occurred in long-term care facilities housing adolescents and young adults (122). However, mumps virus is less transmissible than measles and other respiratory viruses. The low level of mumps transmission in the community results in a low risk for introduction of the disease into health-care facilities. Because mumps is shed by infected persons before clinical symptoms become evident and because infected persons often remain asymptomatic, an effective routine MMR vaccination program for health-care workers is the best approach to prevent nosocomial transmission.
Measles can be severe and prolonged among immunocompromised persons, particularly those who have certain leukemias, lymphomas, or human immunodeficiency virus (HIV) infection. Among these persons, measles may occur without the typical rash and a patient may shed measles virus for several weeks after the acute illness (6,7). Measles Elimination
Note that neither supports your claims.
