Vaccines Global Summit

Hepatitis and Varicella Vaccines have been of great importance in preventing severe cases of viral infections that lead to some serious complications in the patient's health over time. They are integrated into common immunization programs, which have been considerable in their contribution to reducing prevalence rates of diseases such as hepatitis and chickenpox worldwide.

The main focus of the hepatitis vaccines is hepatitis A and hepatitis B viruses, which cause severe liver disease. The hepatitis A vaccine is effective in preventing the hepatitis A virus, which normally spreads mainly through contaminated food and water and causes acute inflammation of the liver. It is usually a short-term illness but sometimes could result in liver failure during severe conditions, normally among older people or those with previous liver illnesses. The vaccine is highly effective in its prevention against hepatitis A infection, thereby recommended for all children, travelers to countries where the virus is very common, and higher-risk groups.

The hepatitis B vaccine is more critical because of the causative agent's propensity to cause both acute and chronic liver infections. Chronic hepatitis B infection places infected people at a significantly higher risk for both liver cirrhosis and liver cancer. The hepatitis B vaccine is given to infants, and it provides lifelong protection. Therefore, it is a very important vaccine tool in preventing the transmission of the virus from mother to child and in reducing the global burden of chronic liver disease. New infections and cases of liver cancer have dramatically fallen in most parts of the world due to hepatitis B vaccination.

The varicella vaccine is used to protect against infection by the varicella-zoster virus (VZV), which causes chickenpox-a severe and contagious disease characterized by an itchy rash and flu-like symptoms. In children, the disease is relatively mild, but complications occur more frequently in adults, pregnant women, and immunocompromised individuals. Before the introduction of the vaccine, chickenpox was another important childhood disease that led to thousands of hospitalizations and hundreds of deaths annually, just in the United States. Routine vaccination with the varicella vaccine has made chickenpox and its complications very infrequent.

Public Health Effects of Hepatitis and Varicella Vaccines

The hepatitis and varicella vaccines have significantly impacted public health by eliminating infections that may cause serious, long-term complications or other severe outcomes. The vaccines are an essential part of all immunization schedules globally, preventing children and adults from being infected by a number of serious viral diseases.
