Nowadays, the issue of vaccination has attracted more and more people''s attention and attention. In life, many parents dare not agree on the quality of our domestic BCG vaccine, and worry about what adverse reactions will occur after their baby is vaccinated. , So I trust the imported vaccine, so what is the difference between imported and domestic BCG vaccine?

　　The difference between imported and domestic BCG vaccine:

　　imported vaccine and domestic vaccine The difference lies in the difference between imported vaccines and domestic vaccine strains and their culture process, as well as the number of antibodies produced, the length of the epidemic prevention, and the size of side reactions.

　　 Domestic vaccines are live attenuated vaccines (OPV). The advantage is that they are easy to use. The above vaccinees produce long-term immunity and can produce specific antibodies sIgA in the intestinal tract. Immune effect can be obtained; but because it is a live virus, it can cause paralysis if it is used in babies with immune deficiency or immunosuppressive therapy.

　　Imported vaccine is an inactivated vaccine (IPV). The advantage is safe. It is generally used for people with immune deficiencies and their family members, and can also be used for those receiving immunosuppressive therapy; but the price is more expensive and the immune maintenance The time is short, and repeated injections are required, and the intestine cannot produce local immunity.

　　 BCG vaccine will appear purulent after vaccination, this is a normal vaccination reaction. Generally, after the BCG vaccination, the immunity is strong, and there will be slight purulent symptoms at the inoculation site, so it is normal for BCG to purify. If there is no purulent, it means that the vaccination may not be successful. You must re-vaccinate. If the vaccination is successful, the purulent will become a stuck scar.

　　Vaccination can make children develop special resistance to tuberculosis, as long as the child has been vaccinated with BCG at the time of birth, there is no need to fight again. The general vaccination time of BCG vaccine is to vaccinate within 24 hours after the baby is born. If the vaccination is not done in time, the baby must be replanted within 2 months. However, in order to ensure that the baby is successfully vaccinated with BCG, a BCG vaccine review is required.
