Infant Mortality

With all of the research Prof. (James) McKenna has done regarding the sudden death of infants for no obvious reason (“Study Questions Custom of Having Babies Sleep Alone,” Feb. 25), he might have studied the case of vaccinations in Japan. After the Japanese raised the minimum age for vaccinations in children to 2 years, sudden infant death syndrome incidents in the under-2-year-old population dropped to almost nothing.

It is hard to believe that a good night’s sleep will kill, but it is documented that vaccines can induce dangerous adverse reactions.
