Currently, there are three types of polio vaccines used to prevent polio in our country: attenuated oral drops, IPV (inactivated polio vaccine) and pentavalent vaccine containing IPV. The IPV vaccine and the IPV-containing pentavalent vaccine are inactivated polio vaccines, which are dead vaccines, eliminating the risk of reversion to virulence and making them safer. There are also many types of combination vaccines, and for the combination vaccine to prevent polio, the pentavalent vaccine containing IPV is a safe choice for polio prevention if the mother’s financial situation allows. According to the national immunization program and instructions, each of these traditional vaccines generally requires 4 doses of vaccination, so that a total of 12 doses are needed to be administered one by one. With the DPT vaccine, only 4 doses are needed to prevent all the diseases mentioned above. The baby gets 8 less doses of vaccination, and the mother makes 8 less trips. 2. Timely vaccination and early completion of basic immunization It is difficult to complete basic immunization before the high incidence of diseases at the age of 6 months with one shot of polio vaccine, inactivated polio vaccine and Haemophilus influenzae type b conjugate vaccine. If the vaccination is then postponed in case of baby’s illness, the accumulation may result in many vaccines not being given in time. If you choose the DPT vaccine, you can easily complete the basic immunization at the age of 4 months because the number of vaccinations is reduced, ensuring timely protection before the onset of disease. It is an ideal vaccination option to give your baby only one shot to prevent multiple diseases at the same time. In fact, the six-dose vaccine has been used internationally, and the five-dose vaccine has been introduced into the immunization program in many developed countries such as the United States and France, and is also used in Hong Kong and Taiwan, so the five-dose vaccine has been widely used and proven to be safe and effective. At present, Chinese babies can also get the protection of this advanced vaccine, which makes the vaccination of babies safer and more convenient. Therefore, mothers must learn about vaccines in advance, choose the right vaccine for their babies, give their babies a safe vaccination experience, be responsible mothers, and give their babies a love without defects.
