How many days after exposure must the Hepatitis B vaccine be offered?

The Hepatitis B vaccine is recommended to be offered within a certain timeframe after exposure to ensure optimal effectiveness at preventing the virus from establishing an infection. The guidelines suggest that the vaccine should be administered as soon as possible, ideally within 14 days of potential exposure.

This timeframe is crucial because the vaccine is most effective at preventing Hepatitis B when given early after exposure. The specific timeframes are based on clinical evidence that demonstrates the immune response generated by the vaccine is best when administered promptly within this period. By adhering to this recommendation, healthcare providers can significantly reduce the risk of developing Hepatitis B in individuals who have been exposed to the virus. Therefore, stating that the vaccine must be offered within 10 days aligns with the recommended practices for post-exposure prophylaxis.
