*High-risk individuals: Suitable for Newborn babies carers (Including domestic helpers, post-natal care workers and parents), 
*85% of new born babies cases are transmitted by family members (4)
*Recommended for vaccination: Suitable for pregnant women (during the second or third trimester of pregnancy), people aged 50 or above, and people with weakened immune systems

Why Do New Born Baby Carers Need Whooping Cough Vaccine?
The rate of pertussis transmitted by family members is relatively high, 85% of new born babies cases are transmitted by family members (4). So it is recommended that caregivers of newborn babies, except for pregnant women, receive the Boostrix vaccine 2 weeks before the baby's birth.

Double infection of COVID and whopping cough cannot be ignored
According to research, patients with COVID who are infected with whooping cough at the same time are more severely ill than those who only suffer from COVID.(3)

Why Do Pregnant Women Need Whooping Cough Vaccine?
From birth to 6 months of age, newborn babies are more susceptible to pertussis infection because they have not yet completed the basic vaccine. The first dose of pertussis vaccine is only started when the baby is 2 months old, and it may take 1-2 months after the injection to produce antibodies, that is, it may not start to have protective effect until 3-4 months old. The 2nd, 3rd, and 4th injections at 6 and 18 months, respectively, have the most comprehensive protection.

Pregnant women who are vaccinated against whooping cough during the second or third trimester of pregnancy can produce antibodies in the mother's body and transmit the antibodies to the baby through the placenta, so that the baby can be protected.

Whooping cough and cold symptoms are very similar
Pertussis (also known as whooping cough) is highly contagious and deadly, spread through droplets from direct contact with a sick person. The initial symptoms of whooping cough are similar to those of a cold and flu. There are also symptoms such as runny nose, sneezing, mild fever and cough. Therefore, in the early stage of the disease, it may be ignored by patients. But the cough can get worse and prevent the patient from eating and breathing. The average duration of cough in adult patients is 5-12 weeks (1). The bacteria can infect the lungs, which can lead to convulsions and coma in severe cases (2).

Extra careful for people with weak immunity level
People with weak immunity, the elderly or those with chronic diseases may find it difficult to recover on their own, and the symptoms after infection are more severe, often complicated by serious diseases such as pneumonia and kidney failure. Vaccination is required to reduce the risk of infection. 

Boostrix Vaccine can effectively prevent whooping cough. Vaccines provide effective protection, and patients who have been vaccinated against whooping cough experience milder disease.

I was vaccinated as a child, do I need to re-vaccinate?
This vaccine is suitable for individuals aged 4 years or older. Antibodies to whooping cough decline over time, and their protective efficacy is about 10 years. According to the U.S. Centers for Disease Control and Prevention, all people with 19 years old or older should receive one dose of the adult pertussis vaccine every 10 years to prevent pertussis, diphtheria, and tetanus.
