HEPATITIS B VIRUS:
 2 in 10 Vietnamese have been infected with the hepatitis B virus
 2 in 10 Vietnamese have been infected with the hepatitis B virus
 Anyone can get hepatitis B by coming into contact with blood, open sores, or body fluids from someone who is infected with hepatitis B.
 Anyone can get hepatitis B by coming into contact with blood, open sores, or body fluids from someone who is infected with hepatitis B. 
 Nearly 90% of infants infected during the first year of life develop chronic infections that can later develop into cirrhosis or liver cancer.
 Nearly 90% of infants infected during the first year of life develop chronic infections that can later develop into cirrhosis or liver cancer. 
==> Prevention of mother-to-child transmission of HBV may be as high as 90% if infants receive hepatitis B vaccine within 24 hours after birth.
==> Prevention of 3 following doses at the age of 2,3,4-month-old may be as high as 95% if infants are contacting with the virus and the protection lasts at least 20 years.
In conclusion: Should be vaccinated against hepatitis B as:
 Mothers who are infected with hepatitis B are at high risk of passing the virus to their child at birth.
 Mothers who are infected with hepatitis B are at high risk of passing the virus to their child at birth. 
 Mothers who test negative for hepatitis B and not vaccinated are still at risk of infection during pregnant, or early testing is difficult to detect.

 Source of infection: blood, open sores, body fluids or sharing the needles, e.g: toothbrush, shaves, etc.

 Pregnant women should have HBV (if she has not vaccinated)

TUBERCULOSIS (TB)
 2 in 1000 Vietnamese infected lung TB and can spread to 15-20 other people

 Easy to spread through respiratory tract when the infected person coughs, especially a person who has not been recognized and treated.

 Once a person is infected with TB virus, it may not develop into active TB unless the immunization system is impaired (especially in children or older people)
 Once a person is infected with TB virus, it may not develop into active TB unless the immunization system is impaired (especially in children or older people)
 Approximately 40% of infected infants aged <1 year old will progress to active TB and to intrathoracic TB which leads to the high rate of death.

==> It is recommended that infants should have TB vaccines soon as high risk of infection from people surrounding. (e.g: from those who infected TB but have not recognized)
