The Hepatitis A vaccine provides long-term protection against the Hepatitis A virus, preventing liver infection. Hepatitis A is a very contagious liver infection caused by hepatitis A virus (sea). The infection usually spreads through contaminated food or intake of water or through close contact with an infected person. Although hepatitis A does not usually cause chronic liver disease, it can cause severe symptoms, including fatigue, nausea, jaundice and abdominal pain. In rare cases, hepatitis A can lead to a full liver failure, especially with older adults and with liver position. Vaccination against hepatitis A vaccine is the most effective way to prevent infection and associated complications.
What is the Hepatitis A Vaccine?
Hepatitis A vaccine is an inactive (killed) virus vaccine that stimulates the immune system to produce sea antibodies. These antibodies provide long -term protection against the virus and prevent infection if a person is exposed. The vaccine is available in one-antizen shape (only for protection against hepatitis A) and in combination with hepatitis B vaccine (twinics), which provides immune to both hepatitis A and hepatitis B.
Who should get a vaccine against hepatitis?
Disease control and Prevention Center (CDC) and the World Health Organization (WHO) recommend hepatitis A vaccination for many main groups, including:
1. Children – Regular hepatitis A vaccination is recommended for all children at the age of 1 year.
2. Passengers – people traveling to countries where hepatitis A is common, including Africa, Asia, Middle and Parts of South America and Middle East, should be vaccinated before departure.
3. People with chronic liver disease – individuals with existing liver disease, such as hepatitis B or C, are at high risk of severe hepatitis A -infection and should be vaccinated.
4. Men who have sex with men (MSM) – MSMs have an increased risk of hepatitis A transfer and are strongly recommended to get a vaccine.
5. Persons using injections or non-injections medicine-specific in shared settings increase the risk of exposure to the sea.
6. Risk workers – people working in surroundings such as health services, childcare, food service and hygiene, where the risk of exposure increases, vaccination may benefit from it.
7. Domestic or careful with an infected person – intimate contact with hepatitis A increases the chances of transfer, making the vaccination significantly.
8. Persons experiencing homeless people – due to limited access to hygiene and health care, people who are homeless high risk of hepatitis are a contract.
9. Everyone has a desire to preserve – since hepatitis A can be entered through contaminated food, water and close contact, so vaccination is a safe and effective alternative for anyone who wants immunity to the virus.
Hepatitis A -vaccine plan
Hepatitis A vaccine is usually given in two doses, separated six months. This two-khurak chain provides long-term security, possibly permanently throughout life. For those passengers who require rapid protection, the same dose of the vaccine may cause short -term immune, but the other dose is necessary for long -term protection. For those who receive hepatitis A and B vaccine (Twinerics), the three-kherit plan is followed in six months.
Efficiency and safety for vaccines
Hepatitis A vaccine is very effective, with more than 95% vaccinated individuals gain immunity after the first dose and receives about 100% complete protection after the second dose. Immunity usually lasts for at least 20 years and can persist for life.
The vaccine is considered safe, in most cases only with mild side effects. These may include:
●Agony at the injection site
●Fever with low degree
●Fatigue
●Headache
Serious allergic reactions are extremely rare. People with history of severe allergic reactions for any vaccine component should consult the health care provider before receiving hepatitis A vaccine.
Why is hepatitis A vaccination important?
•Prevents outbreak-hepatitis A outbreaks can occur in local communities, especially where hygiene conditions worsen. Extensive vaccination helps prevent such outbreaks.
•Protects high -risk population people who are most exposed to serious illness, including people with liver diseases and chronic adults, can avoid complications through vaccination.
•Reduces the cost of the health care system through intake is far more cost -effective than the treatment of hepatitis A, which can be admitted to hospitals, and loses productivity and medical expenses.
•Supports public health goals – as more people are vaccinated, the general spread of hepatitis A A is reduced, leading to better social health.
Conclusion
Hepatitis A Vaccine is still an important public health problem in many parts of the world. However, through effective vaccination programs, the incidence of the disease has decreased dramatically. Hepatitis A vaccine is safe, efficient and recommended for children, travelers, high risks, and is a desire to preserve some. By taking informed and preventive measures through vaccination, individuals can protect themselves and their communities from the spread of hepatitis A. If you are unsure of your hepatitis A vaccine, you can contact health care professionals for guidance.
