CHRISTIAN J. MORAN, Special Master.
RMR, daughter of petitioner Marissa Arevalo, was born in March 2012. At approximately two months of age, on Thursday, May 10, 2012, RMR received a dose of the diphtheria-tetanus-acellular pertussis (DTaP) vaccine. By Monday, May 14, 2012, medical personnel were documenting seizures consistent with infantile spasms. Doctors have since confirmed the diagnosis of infantile spasms, a horrible condition that prevented RMR's development.
Ms. Arevalo alleges that the DTaP vaccination harmed RMR. The petition asserts two causes of action, one based on the Vaccine Table, and the other an off-Table claim. To address the on-Table claim, a hearing was held. In this hearing, Ms. Arevalo produced persuasive evidence that showed RMR suffered an "encephalopathy" as the regulations define that term. Therefore, Ms. Arevalo is entitled to compensation.
Congress created the Vaccine Program to promote recovery for people injured by vaccinations. In doing so, Congress created a table that associates certain vaccines with certain conditions that arise in a certain amount of time. When a petitioner establishes an on-Table injury, there is a presumption that the vaccine caused the injury. The Secretary may rebut this presumption with other evidence.
The current version of the table is found at 42 C.F.R. § 100.3(a). (For a discussion about the Secretary's authority to modify the Vaccine Table,
Through Qualifications and Aids to Interpretation, the Secretary has further defined "encephalopathy." An "acute encephalopathy" means "one that is sufficiently severe so as to require hospitalization (whether or not hospitalization occurred)." 42 C.F.R. § 100.3(b)(2)(i). For children who are less than 18 months of age, including RMR, "an acute encephalopathy is indicated by a significantly decreased level of consciousness lasting for at least 24 hours." 42 C.F.R. § 100.3(b)(2)(i)(A). The definition of the critical phrase "significantly decreased level of consciousness" is found in paragraph D. This provision provides:
42 C.F.R. § 100.3(b)(2)(i)(D).
The Secretary has also excluded some factors from contributing to an "encephalopathy."
42 C.F.R. § 100.3(b)(2)(i)(E).
This regulatory structure means the field of evidence relevant to determining whether RMR suffered an encephalopathy is relatively circumscribed. Evidence is relevant if it tends to show or tends not to show that RMR suffered a "decreased level of consciousness" arising within 72 hours of vaccination and persisting for 24 hours. The factors for a "decreased level of consciousness" include: (1) a decreased response to the environment, (2) decreased eye contact, or (3) an inconsistent response to external stimuli. 42 C.F.R. § 100.3(b)(2)(i)(D). Conversely, evidence about fussiness, inconsolable crying, etc. is not relevant. 42 C.F.R. § 100(3)(b)(2)(i)(E).
The hearing was held because the parties disputed RMR's health in the 72 hours after the vaccination. The parties, however, agree about RMR's health before the vaccination on May 10, 2012, and after May 15, 2012.
On May 10, 2012, RMR was seen for her two-month well baby visit with her pediatrician, Dr. Ho. Dr. Ho noted no health concerns. Exhibit 4 at 10-11. It is likely that by two months, RMR was able to track an object with her eyes.
The other bookend to the debate is that on Monday, May 14, 2012, RMR's parents brought her to the emergency room at Saint Francis Medical Center in Peoria, Illinois. Exhibit 5 at 3. They were concerned that RMR was having seizures. Id.; Tr. 54-56. While in the hospital, RMR's parents gave various accounts of her condition since the vaccination approximately four days earlier. E.g., exhibit 5 at 3, 13-14. Although the histories are not absolutely consistent, the records created on Monday evening tend to show that RMR's seizures started early Sunday morning, perhaps 1:00 or 2:00 AM. Exhibit 4 at 18; exhibit 5 at 16, 21;
It is sufficient to note that after the seizures, RMR's development essentially halted. See Tr. 41, 141-43. Today, RMR requires a G-tube and a wheelchair. Ms. Arevalo spends almost all her time caring for her. Tr. 16-17, 124-26.
The issue requiring more thorough analysis is RMR's health between 3:00 PM Thursday and 3:00 PM Sunday. In this time, did RMR experience symptoms of a "decreased level of consciousness?"
Here, Ms. Arevalo has produced sufficient evidence to answer this question affirmatively. In the initial consultation with Dr. Zelaya, which occurred relatively late in the evening on Monday, May 15, 2012, after RMR had been admitted to the hospital, Dr. Zelaya obtained the following history from Ms. Arevalo: "The mother has observed that the infant did have good eye tracking except in the last couple of days." Exhibit 5 at 41. Several aspects are significant. As mentioned earlier, it is not surprising for a two-month infant to track objects. Moreover, Ms. Arevalo used the phrase "last couple of days." Because Dr. Zelaya was seeing RMR on Monday, two days places the problem of tracking at some time on Saturday, well before the Sunday 3:00 PM cut off. Ms. Arevalo's observation that her daughter was not tracking with her eyes could have occurred only when RMR was awake on Saturday. This sequence means that the decreased eye tracking must have started before the seizures, which began on Sunday morning.
Dr. Zelaya created his May 15, 2012 record within two days of the decrease in eye tracking, meaning that the account is presumptively accurate.
One way to demonstrate a "decreased level of consciousness" is to show "decreased or absent eye contact." 42 C.F.R. § 100.3(b)(2)(i)(D)(2). Here, the lack of tracking in a two-month old fulfills this criterion. After Ms. Arevalo establishes that RMR suffered the regulatory definition of an encephalopathy, Ms. Arevalo is entitled to a presumption that the DTaP vaccine caused the associated injury.
The Vaccine Act affords the Secretary an opportunity to rebut the presumption of causation. 42 U.S.C. § 300aa-13(a)(1)(B);
A separate order for the damages phase of the case will issue shortly.
