Rabies occurs in more than 150 countries, causing 59,000 human deaths every year. It is a viral disease that, without proper treatment, leads to death in almost 100% of cases within a short period. The estimated demand for the rabies vaccine is around 64 million doses and globally, rabies causes an estimated cost of US$8.6 billion per year. Of the 24 rabies vaccine manufacturers registere…

Yellow Fever is an infectious and non-contagious disease caused by the Yellow Fever Virus (YFV), an arbovirus belonging to the Flaviviridae family. It has a broad spectrum of symptoms, ranging from asymptomatic to severe and fatal cases. Recently, a study conducted by the Laboratory of Allergy and Clinical Immunopathology, showed that absolute neutrophil count in peripheral blood was inde…

In humans, influenza is caused by influenza viruses (IVs), predominantly types A (IAV) and B (IBV), and constitutes a global public health problem, responsible for 3 to 5 million cases and 290 to 650 thousand deaths annually worldwide. IAVs have been responsible for various pandemics throughout history, such as the Spanish flu pandemic, Asian flu, swine flu, among others. Currently, exist…
Influenza viruses are capable of infecting humans and animals, are widely distributed and can cause seasonal epidemics associated with highly contagious respiratory infections that can be caused by more than one type of influenza virus, with the most prevalent infections caused by the influenza A virus (IAV). IAVs represent a very diverse group due to the antigenic variations associated w…
Influenza virus can cause mild to severe respiratory infections in humans, still being a serious public health problem. According to the World Health Organization (WHO), seasonally circulating influenza viruses cause approximately 3 to 5 million severe cases and 290 to 650,000 deaths per year. Vaccines and antiviral drugs are the main strategies used against the virus. The influenza vacci…
Evidence has shown that chronic viral infections promote excessive and continuous immune activation, which can lead to a state of cellular exhaustion and senescence, usually associated with changes in telomere length. Chronic infection with human immunodeficiency virus (HIV), even in association with prolonged exposure to antiretroviral therapy (ART), can accelerate the process of immune …
The influenza virus remains a threat to public health. According to the World Health Organization (WHO), it is estimated that annual epidemics result in about 3 to 5 million severe cases and up to 650,000 deaths worldwide. Two main strategies are used against the virus, such as vaccines and antiviral drugs. Influenza vaccine requires annual reformulation to keep up with the expectation of…
