In recent years, there have been many different types of vaccines, and many parents are confused as to what the first and second types of vaccines are. Why are there free vaccines and self-funded vaccines, and what is the difference between them? Which vaccine is better for babies and how should we choose? The second type of vaccine should not play and many other questions, here we are here to answer for you, to relieve your worries about the choice of vaccines. According to the Regulations on the Administration of Vaccine Circulation and Preventive Vaccination, vaccines are categorized into two types. The first type of vaccine refers to the vaccines that the government provides free of charge to its citizens, and the citizens should be vaccinated in accordance with the government’s regulations. The second category of vaccines refers to those vaccines that are provided by the government free of charge to citizens and that citizens should receive in accordance with the government’s regulations. The two types of vaccines have their own advantages and disadvantages 1, take polio vaccine, a type of vaccine for the domestic oral more convenient, the second type of vaccine for the injection to the baby inoculation to bring a certain degree of pain, the two types of vaccines have their own advantages and disadvantages. 2, from the point of view of disease prevention can achieve the purpose of preventing polio. Oral vaccines have very few children with vaccine-related polio and vaccine-derived poliovirus. In addition, the oral vaccine is a live vaccine, half an hour before and after taking the vaccine can not breastfeed or drink hot water. 3, from the point of view of disease prevention, a type of vaccine can completely achieve the purpose of disease prevention. The use of vaccines over the decades has confirmed this. The safety of the second type of vaccine may be better, but it requires a certain cost. 4, the advantage of the five vaccines is that the vaccination of a five vaccine can prevent five types of common childhood infectious diseases at the same time, can greatly reduce the frequency of vaccination due to the baby’s pain. But the price of imported vaccines is expensive and will bring a certain economic burden to the family. How to choose between domestic and imported vaccines? The imported vaccine (self-funded) is mainly GlaxoSmithKline Hepatitis B vaccine, which is different mainly in the production process, in addition to the price is more expensive. Nowadays, the production process of vaccines in China is constantly improving, and the quality of domestic vaccines is very good. There is no significant difference between imported and domestic hepatitis B vaccines in terms of immune response after vaccination. Is there a need for the second type of vaccine? We believe that if the family’s economic conditions allow, it is possible to be vaccinated. Especially premature babies and frail children have higher chances of contracting vaccine-related diseases due to their weaker immune function, and the probability of vaccine-related diseases will be greatly reduced after vaccination with Type II vaccine. Principles of vaccination 1. Two inactivated vaccines or one live attenuated vaccine and one inactivated vaccine can be inoculated on the same day in different parts of the body. 2. One injectable live attenuated vaccine and one oral live attenuated vaccine can be vaccinated on the same day. 3. An interval of more than 28 days is required between the two vaccines administered at the same site on the same side. 4. Two kinds of injectable live attenuated vaccines should be vaccinated on the same day, otherwise, an interval of 28 days is required.
