Moreover, in some regions, a lack of harmonization of vaccination strategies and selection of high-risk populations have contributed to insufficient vaccination coverage of some target groups [ 42].
This in turn has contributed to insufficient understanding of the role of CHAs and potentially contributed to limited perceptions of CHAs as being fully part of the health system.
In some regions, the lack of harmonization of vaccination strategies and of selection of high-risk populations has contributed to insufficient vaccination coverage of some target groups [ 9, 42].
Such lack of knowledge among health workers could translate into similarly deficient knowledge in the general population, thereby contributing to insufficient preventive practices that enable the persistence of high rates of HBV infection.
Poor breastfeeding technique or latching leading to ineffectual milk removal, deficient mammary gland tissue and maternal hormonal imbalances can all contribute to insufficient supply of milk [ 14, 15].
The small sample sizes and heterogenous patient background in the clinical studies contribute to insufficient power to investigate the value of both dosing methods.
However, this lack of convincing data may be due to several methodological flaws and inconsistencies among the available studies, thus contributing toward insufficient power to detect any significant differences between CI and IB, if they exist.
The excessive sympathy which flows to perpetrators like Turner both owes and contributes to insufficient concern for the harm, humiliation, and trauma they cause to their victims.
Limited persistence of CTL following adoptive transfer into tumor-bearing hosts is one factor that contributes to insufficient anti-tumor immune responses, and previous studies have shown that tumor-infiltrating lymphocytes are primed to undergo apoptosis [14].
