The challenges faced in delivering lifesaving vaccines to the targeted beneficiaries need to be addressed from the existing knowledge and learning from the past. This review documents the history of vaccines and vaccination in India with an objective to derive lessons for policy direction to expand the benefits of vaccination in the country. A brief historical perspective on smallpox disease an...

Bacillus Calmette-Guérin (BCG) is a vaccine used to prevent tuberculosis. It made from live, attenuated strain of Mycobacterium bovis . When injected into the human body, it causes mild infection that produces immunity tuberculosis bacterium. The BCG primarily as preventive measure against in children, and generates special resistance disease. To honor its inventors, French scientists Ca...

INTRODUCTION The propensity for influenza viruses to mutate and recombine makes them both a familiar threat and a prototype emerging infectious disease. Emerging evidence suggests that the use of MF59-adjuvanted vaccines in older adults and young children enhances protection against influenza infection and reduces adverse influenza-attributable outcomes compared to unadjuvanted vaccines. The he...

Effective and safe vaccines against lumpy skin disease (LSD) are already commercially available. Large-scale vaccination combined with other appropriate control measures, can eliminate the outbreaks. In the absence of appropriate DIVA vaccines, carrying out preventive vaccination against LSDV in disease free but at-high risk countries, inflicts heavy export restrictions on live cattle and their...

The best long-term hope for controlling the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) pandemic is a safe, effective and affordable preventive vaccine, but its development has encountered unprecedented scientific challenges. The first phase I trial of an HIV vaccine was conducted in 1987. Subsequently, more than 30 candidate vaccines have been tested in over 60 p...

Developing and disseminating a preventive HIV vaccine is a primary scientific and public health objective. However, little is known about HIV vaccine acceptability in the high-prevalence setting of South Africa- where young adults are likely to be targeted in early dissemination efforts. This study reports on six focus groups ( n = 42) conducted in 2007 with South Africans aged 18 to 24 years. ...

Controlling the global COVID-19 pandemic depends, among other measures, on developing preventive vaccines at an unprecedented pace. Vaccines approved for use and those in development intend to elicit neutralizing antibodies block viral sites binding host’s cellular receptors. Virus infection is mediated by spike glycoprotein trimer virion surface via its receptor domain (RBD). Antibody response...

BACKGROUND About two million people annually travel to Kingdom of Saudi Arabia to perform Hajj. The pilgrims may be at risk of exposure to communicable diseases in this mass gathering and their vaccination against contagious diseases can prevent many morbidities and mortalities. The aim of our study was to review the papers which evaluated effectiveness and compliance of the vaccines applied in...

Critical to the development of an effective HIV vaccine is the identification of adaptive immune responses that prevent infection or disease. In this study we demonstrate in a relevant nonhuman primate model of AIDS that the magnitude of vaccine-induced virus-specific CD8(+) central memory T cells (T(CM)), but not that of CD8(+) effector memory T cells, inversely correlates with the level of SI...

Background and Aims: Newcastle disease (ND) is a highly contagious disease in poultry with economic losses in the world. Vaccination is one of the most important ways for prevention and control of NDV, but there are reports of ND outbreaks in vaccinated chickens. Poor quality of the vaccines is one of the reasons of vaccine failure. In this study the quality of two commercial oil-emulsion Newca...
