A new study compared the vaccine's effectiveness Heplisav-B, a new hepatitis B vaccine, with that of traditional hepatitis B vaccines.
The study showed that a single booster dose of the Heplisav-B vaccine is likely sufficient for the majority of healthy young healthcare workers who have already received the full vaccination series. This simplifies the vaccination program while ensuring enhanced protection against the virus.
The study was conducted by researchers from the Department of Family Medicine at the Uniformed Services University in Maryland, USA, and its results were published on March 24 in the journal "The Annals of Family Medicine." The site EurekAlert also reported it.
In recent years, vaccine development has made significant progress, particularly in the fight against viral infections such as hepatitis B. Healthcare workers, who are regularly exposed to patients' blood and other bodily fluids in the course of their work, are at greater risk of contracting hepatitis B infection, making vaccination essential to ensure their protection.
Hepatitis B
Hepatitis B is a viral infection that attacks the liver and can cause acute or chronic illness.
The virus is usually transmitted from mother to child at birth, during infancy, or through exposure to bodily fluids, unsafe injections, or sharp objects.
Most people recently infected with hepatitis B experience no symptoms. However, some may experience acute symptoms lasting several weeks, such as yellowing of the skin and eyes (jaundice), dark urine, severe fatigue, nausea, vomiting, and abdominal pain. In severe cases, acute hepatitis can lead to liver failure, which can be fatal.
Although the majority of people recover from the acute form, somees develop chronic hepatitis B, which can lead to serious liver diseases, such as cirrhosis or hepatocellular carcinoma. These complications can be fatal. However, hepatitis B can be prevented with safe, available, and effective vaccines.
Hepatitis B vaccines
The hepatitis B vaccine is used to prevent infection with the hepatitis B virus. It stimulates the immune system to produce antibodies against the disease.
This vaccine is available only through a doctor or licensed healthcare professional. It offers nearly 100% protection against the virus.
Traditional hepatitis B vaccines require three doses over a six-month period. In contrast, the Heplisav-B vaccine is administered in two doses.
