There are some who believe that some cases of SIDS are related to DTaP shots. This is by and large impossible to prove unless you do a large scale study comparing rates in vaccinated vs unvaccinated populations, and no such study has ever been done. Even vaccine trials compare experimental groups against ‘control’ groups that are receiving either standard vaccines or other experimental vaccines- not much of a control group at all. To date, no studies have conclusively proven there is an increased risk of SIDS in the 2 week period immediately following DTaP shots.
Some people find it suspicious that the peak incidence of SIDS occurs between 2-4 months, just when the first two series of shots are given. No explanation has ever been given for why the rate is lower in the second month of life than in the third through fifth. On the other hand, vaccine manufacturers attribute this to ‘coincidence’ and the general consensus is that SIDS happens to peak at 2-4 months, which just happens to be when the first shots are given. Adding to concerns is the fact that SIDS decreased to almost nothing following a postponement of DTaP to age 2 years in the Japanese vaccination schedule, and rose again when the vaccine was once again given starting at 2 months.
"Delay of DPT immunization until 2 years of age in Japan has resulted in a dramatic decline in adverse side effects. In the period of 1970-1974, when DPT vaccination was begun at 3 to 5 months of age, the Japanese national compensation system paid out claims for 57 permanent severe damage vaccine cases, and 37 deaths. During the ensuing six year period 1975-1980, when DPT injections were delayed to 24 months of age, severe reactions from the vaccine were reduced to a total of eight with three deaths. This represents an 85 to 90 percent reduction in severe cases of damage and death. (Ref21)."---Raymond Obomsawin, MD
“Some people, including some medical researchers, believe that vaccines are one cause of SIDS. Harris Coulter and Barbara Loe Fisher, in their book DTP: A Shot in the Dark, reviewed all available information and medical literature on the topic and estimated that 10 percent of all SIDS cases are caused by DTP vaccine. Viera Schiebner, Ph.D., author of Vaccination:100 Years of Orthodox Research Shows That Vaccines Represent a Medical Assault on the Immune System, says one study found that in the United States, the peak incidence of SIDS is between the ages of two and four months, when the first two mandatory vaccines are given (at the time of her study, they were DTP and polio), and that another study found a clear pattern of SIDS up to three weeks after immunization. A third study noted that each year three thousand children die within four days of vaccination. And in the late 1970s when Japan raised their DTP vaccination age form two months to two years, the death claims for DTP in Japan’s Compensation Program dropped.”

Studies on Cardiopulmonary Side Effects of DTap in Preemies and Low-birthweight Babies
There have been some studies done that showed increased risk of bradycardia, apnea, and oxygen desaturation following the administration of DTaP, prior to discharge, to preemies born at 32 weeks of gestation or less. No difference was noted in frequency of these event following DTP vs. DTaP.
See study here
Studies have also been done that showed significant risk or a cardiopulmonary event following DTaP in very low-birthweight babies. See study here.
The implications such studies may or may not have for full-term, normal birth weight infants is unknown and despite the above concerns, the official consensus at this time is that SIDS is not related to vaccination.
