Haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. The disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. Despite the availability of new and more powerful antibiotics children with Hib meningitis still suffer from high mortality or morbidity. The emergence of multir...

Background: Quick vaccine rollouts and compliance with preventive strategies are crucial for a country recovery from COVID-19, but hesitancy could prolong the pandemic need for physical distancing lockdowns. Aim of study: was to assess levels COVID-19 vaccine hesitancy, protective behaviors risk perception among university students in Alexandria. Study design: An online cross-sectional expl...

Human enterovirus 71 (EV71) is a significant cause of morbidity and mortality from Hand, Foot and Mouth Disease (HFMD) and neurological complications, particularly in young children in the Asia-Pacific region. There are no vaccines or antiviral therapies currently available for prevention or treatment of HFMD caused by EV71. Therefore, the development of therapeutic and preventive strategies ag...

This commentary takes up Pearl's welcome challenge to clearly articulate the scientific value of principal stratification estimands that we and colleagues have investigated, in the area of randomized placebo-controlled preventive vaccine efficacy trials, especially trials of HIV vaccines. After briefly arguing that certain principal stratification estimands for studying vaccine effects on post-...

Background: Potency evaluation of rabies vaccine is a cheap, fast, high precision and consistent with ethical values is critical, so researchers have modified a variety of methods such as: National Institute of Health (NIH) method, Single Radial Immunodiffusion (SRID) and so on. The purpose of the present study was to replace an in vitro method consistent with medical ethics criteria instead of...

Human papillomavirus (HPV), particularly type 16, has been associated with more than 99% of cervical cancers. There are two HPV oncogenic proteins, E6 and E7, which play a major role in the induction and maintenance of cellular transformation. Thus, immunotherapy targeting these proteins may be employed for the control of HPV-associated cervical lesions. Although the commercially available prev...

The common reported adverse impacts of COVID-19 vaccination include the injection site’s local reaction followed by various non-specific flu-like symptoms. Nevertheless, uncommon cases of vaccine-induced immune thrombotic thrombocytopenia (VITT) and cerebral venous sinus thrombosis (CVST) following viral vector vaccines (ChAdOx1 nCoV-19 vaccine, Ad26.COV2 vaccine) have been reported. This liter...

Copyright © 2013 Massachusetts Medical Society. Vaccines are among the most effective interventions in modern medicine. Ever since Edward Jenner’s first use of a vaccine against smallpox in 1796 (see text box), the use of vaccines has become indispensable to the eradication of disease. In the 20th century alone, smallpox claimed an estimated 375 million lives, but since 1978, after the completi...

0387 Vaccines are important preventive medicines for primary health care, and are a critical component of a nation’s health security. Although international agencies such as the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) promote global immunisation drives and policies, the success of an immunisation programme in any country depends more upon local realities ...
