A few hours after the first vaccine dose, 1 child experienced seizures, which resolved spontaneously

2 weeks after the first vaccine dose, another child was diagnosed with acute bronchiolitis and subsequently died due to respiratory distress (Faingezicht 2002)

1 acute bronchiolitis case, due to respiratory syncytials virus infection, occurred 3 days after the first vaccination. The child recovered after treatment and hospitalisation (Faingezicht 2002)

5 participants were hospitalised or experienced a serious adverse event, including 1 participant who died as a secondary result of sudden infant death syndrome 52 days after the first dose vaccine (Greenberg 2000)

3 events: one hypotonic‐hyporesponsiveness, 2 seizures (Nolan 2001)

3 events of seizures (Nolan 2001)

In 1 case 4 booster doses were followed by unsolicited grade '3' symptoms (pharyngitis and severe asthma) (Santos 2002)

12 serious adverse events were reported by 10 participants (Tregnaghi 2006)

2 serious adverse events after the primary vaccination course were reported by 2 participants (Tregnaghi 2006)

4 serious adverse events occurred in subjects receiving DTPw‐HBV/HIB 2.5 vaccine. 2 hypotonic‐hyporesponsive episodes (HHE) in HIB‐078 and 2 cases of convulsions in HIB‐079. All 4 participants recovered (Ortega‐Barria 2007)

2 events occurred following the administration of Tritanrix™‐Hep B and Hiberix™ vaccines in HIB‐078. 1 case of HHE and one case of viral meningoencephalitis (Ortega‐Barria 2007).

2 siblings (twins) presented with symptoms of fever and decreased feeding 17 days after the second dose of vaccine (Shan 5) with one of them progressing to seizures.

A diagnosis of septicaemia with meningitis was made. Another infant presented 10 days after the first dose of Shan 5 with symptoms of fever, irritability and breathlessness, a condition which upon investigation was diagnosed as bronchiolitis (Rao 2009)

DTPw‐HBV/HIB: diphtheria, tetanus, whole cell pertussis/hepatitis B virus/H. influenzae type B
HHE: hypotonic‐hyporesponsive episode

7 SAEs were hospitalisations due to vaccination‐related common childhood infections (Avdicova 2002).

10 SAEs including one drop‐out following a serious adverse event and another following a non‐serious adverse event (Gabutti 2004). 1 case of large, local reactions after the second and third injections (Mallet 2000)

11 SAEs were hospitalisations due to vaccination‐related common childhood infections (1 erythematous rash) (Avdicova 2002).

10 SAEs  including one drop‐out following a serious adverse event (Gabutti 2004).

3 infants presented symptoms that were considered as a contradiction for further vaccination:inconsolable crying i.e. more than three hours after first dose (n = 1), second dose (n = 1) and third dose (n = 1) (Mallet 2000)

2 episodes of "inconsolable crying" were reported within the context of multiple severe local reactions without further sequelae (Mallet 2000).

4 serious adverse events were reported (Aristegui 2003).

8 serious adverse events occurred (Schmitt 2000)

1 SAE was assessed as probably related to vaccination, a hypotonic hyporesponsive episode (Marshall 2010)

26 SAEs were reported during the study. All were considered unrelated to vaccination by the investigators (Marshall 2010)
