Children with cancer may be immunocompromised as a result of their primary underlying disease and/or the use of prolonged and intensive chemotherapy administered with or without irradiation. The damage to the immune system varies with the age of the patient, the type of cancer, and the intensity of the chemotherapy used to treat it. This review analyses the data regarding the immunogenicity, ef...
OBJECTIVE The WHO aims for 90% coverage of the Expanded Program on Immunization (EPI), which in Guinea-Bissau included BCG vaccine at birth, three doses of diphtheria-tetanus-pertussis vaccine (DTP) and oral polio vaccine (OPV) at 6, 10 and 14 weeks and measles vaccine (MV) at 9 months when this study was conducted. The WHO assesses coverage by 12 months of age. The sequence of vaccines may hav...
Cancer vaccine feasibility would benefit from reducing the number and duration of vaccinations without diminishing efficacy. However, the duration of in vivo studies and the huge number of possible variations in vaccination protocols have discouraged their optimization. In this study, we employed an established mouse model of preventive vaccination using HER-2/neu transgenic mice (BALB-neuT) to...
We consider three regions with different public health conditions. In the absence of migration among these regions, the first two have good health conditions and the disease free state is stable; for the third region, on the other hand, the only stable state is the endemic one. When migration is included in the model, we assume that the second region has a disease risk that makes its inhabitant...
Questions have been raised about Guillain-Barré syndrome (GBS) after vaccinations since the 1976 Swine flu vaccine was associated with a 7to 8-fold increased risk for GBS in the 6 weeks after vaccination, resulting in about 1 excess case of GBS per 100 000 vaccinees. There is evidence to support several possible biological mechanisms for the development of GBS, but no one has been able to deter...
A global effort to develop vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began early in 2020. In mid-December, the U.S. Food and Drug Administration approved emergency use authorization for two that successfully concluded their phase 3 trials (1), vaccine distribution United States shortly afterwards.
