Those studies also explain why;
..Measles outbreaks have occurred in schools with vaccination rates over 98 % in all parts of the U.S. including areas that had reported no cases of measles for years. As measles immunization rates rise to high levels measles becomes a disease seen only in vaccinated persons. An outbreak of measles occurred in a school where 100 % of the children had been vaccinated. Measles mortality rates had declined by 97 % before measles vaccination was instituted; http://www.newswithviews.com/Howenstine/james.htm
In Zhejiang province in China, more than 99 percent of all the children have been vaccinated against measles with the MMR vaccine, but the disease still runs rampant! So much for vaccine-induced herd immunity;

..following live virus measles vaccination, measles virus RNA was detected in 10 of 12 children, as early as one day or as late as 14 days after vaccination; https://www.ncbi.nlm.nih.gov/pubmed/7494055
This report documents measles transmission from an individual with verified secondary vaccine failure..

What happened in Samoa is exactly what happened in Croatia with the more severe vaccine-strain measles infection, shedding and transmission (both post vaccination); .."This case report demonstrates that excretion of Schwarz measles virus occurs in vaccinees." https://www.eurosurveillance.org/content/10.2807/ese.15.35.19652-en
