Family of vaccines to introduce myself

Vaccine forest, and often some mother can not touch the mind. Family may wish to hear--vaccine introduced in Heilongjiang province, Deputy Director of the Centers for disease control and prevention programme Yanbinmany mother with child vaccine will take a look at manual, you will find some unfamiliar terms, what "live attenuated hepatitis a vaccine," "inactivated vaccines" and "recombinant vaccine". When the doctor when you ask your child what kind of vaccine inoculation, if you do not know this, inevitably be confused, so may wish to give their own tuition next lesson in this regard. Although the classification method of vaccine lots, but are classified by the classification is based on vaccine properties. Live attenuated hepatitis a vaccinelive attenuated hepatitis a vaccine comes from pathogenic viruses or bacteria. These pathogenic viruses and bacteria in the laboratory after repeated long-term cultivation, toxicity to weaken and was eventually converted into growth and stimulate the immune system with replication, while vaccines do not cause disease. Administration of live attenuated vaccine also artificially was infected by human "disease", of course, this "disease" is very minor, only to be a side effect. Live attenuated hepatitis a vaccine immunization generally only once, and the smaller, consolidating the immune effect, maintaining a long time. But live attenuated hepatitis a vaccine should be saved in low temperature conditions and transport shall be valid for a relatively short, toxicity risk of reversion. Common live attenuated hepatitis a vaccinefor intradermal injection of BCG vaccine, live, oral polio vaccine, measles mumps rubella combined live attenuated hepatitis a vaccine, live attenuated hepatitis a vaccine, Japanese encephalitis live attenuated vaccine, chickenpox vaccine, and so on. Inactivated hepatitis a vaccineinactivated vaccines is the growth of bacteria or viruses in the media, and then after heat or chemical treatment make it inactivated, eventually made into vaccines. General inoculation of inactivated vaccines don't produce immunity protection for the first time, but you can start the immune system, in the second, third after the vaccination, will produce a protective immune response. Immunization with inactivated vaccine produced antibodies will disappear over time, so some inactivated vaccines require regular vaccinations. Inactivated vaccine is relatively poor, maintenance time is short, but more stable and easier to save. Commonly used vaccine, inactivatedadsorbed diphtheria pertussis tetanus combined vaccine, adsorbed diphtheria tetanus combined vaccine, influenza vaccine, inactivated hepatitis a vaccine, rabies vaccine, and so on. Polysaccharide vaccinepolysaccharide vaccines is a special type of subunit vaccine, this vaccine is composed of some of the surface membrane of bacteria composed of long chains of sugar molecules. Children under 2 years old on polysaccharide vaccines are not necessarily immune, may be due to immune system is not mature. Common polysaccharide vaccineGroup A+C main meningococcal polysaccharide vaccine, pneumococcal polysaccharide vaccine, typhoid Vi polysaccharide vaccine, Haemophilus influenza type b vaccine. Genetic engineering vaccinevaccines Antigen can also be used in cell and Molecular Biology Engineering and technology development, through genetic engineering production, these products are sometimes referred to as recombinant vaccines. In fact belongs to the inactivated vaccine. Major recombinant Antigen, recombinant vector vaccines, DNA vaccine, transgenic plant vaccines.
