Many parents choose quadruple or quadruple vaccines at their own expense in order to vaccinate their babies less frequently. Both quadruple and quadruple vaccines are self funded programs that can prevent various diseases, with the most obvious advantage being the reduction of multiple vaccine doses. Next, what are the four link and five link vaccines introduced in the encyclopedia?
What is the quadruple vaccine
The quadruple vaccine is a vaccine that can simultaneously prevent four diseases, mainly targeting infants and young children aged 3 months to 5 years old. It is used to prevent infectious diseases such as diphtheria, pertussis, and tetanus (these three diseases are often collectively referred to as "white pertussis") and infectious diseases such as pneumonia, meningitis, otitis media, and cellulitis caused by Haemophilus influenzae type B (HIB).
The quadruple vaccine is a multi valent vaccine. Multi dose vaccine, also known as combination vaccine, generally refers to a vaccine that combines vaccine components for multiple diseases and can prevent multiple diseases with one dose. According to this definition, China has used multiple vaccines for many years: in the last century, there were DPT vaccine, white tetanus vaccine (to prevent diphtheria, pertussis and tetanus), and in this century, there were leprosy vaccine, mumps vaccine, leprosy vaccine (to prevent measles, mumps, rubella), and A hepatitis B vaccine (to prevent hepatitis A and B).
What is the pentavalent vaccine
The pentavalent vaccine is actually a quadruple vaccine (white pertussis+polio) and a Haemophilus influenzae vaccine. The former is a liquid, the latter is a freeze-dried powder, and the former dissolves the latter to become a pentavalent vaccine. Two types of vaccines are produced separately and packaged together to make a pentavalent vaccine. Two types of vaccines are produced with their own batch numbers, and are packaged as pentavalent vaccines before being given another batch number.
The pentavalent vaccine refers to a combination of five live or inactivated organisms or purified antigens, formulated by producers to prevent multiple diseases or diseases caused by different types or serotypes of the same organism. The pentavalent vaccine is definitely not a simple combination vaccine, each combination vaccine is an independent and scientifically researched vaccine. The pentavalent vaccine generally refers to a combination vaccine of diphtheria, pertussis, tetanus, poliomyelitis, and Haemophilus influenzae. The pentavalent vaccine not only reduces the total number of doses required to prevent these five diseases from 12 to 4, but also provides babies with the same level of immune protection as a single vaccine.
