What are the six recommended Category II vaccines?
As the COVID-19 epidemic is gradually brought under control, people are paying more and more attention to vaccination. Category II vaccines are relatively little known to everyone, so what are the six recommended Category II vaccines? This article will introduce and elaborate in detail from four aspects: vaccination objects, vaccination dose, vaccination time and vaccine precautions.
1. Suitable subjects for vaccination
For Category II vaccines, the suitable recipients of different vaccines are not necessarily the same. For example, rotavirus vaccine is mainly suitable for infants aged 6 weeks to 8 months, while influenza vaccine is suitable for high-risk groups such as the elderly and those with chronic diseases. Additionally, the chickenpox vaccine is available for children and adults. Before vaccination, you must make corresponding selections based on different suitable vaccination targets.
2. Inoculation dose and frequency
The dose and frequency of vaccination are important factors to consider when vaccination. In order to ensure the effectiveness of vaccination, the dosage and frequency of vaccination will vary. Taking the hepatitis B vaccine as an example, adults receive 3 shots, with an interval of 1 month between the first and second shots, and a 6-month interval between the 2nd and 3rd shots. For the vaccine corresponding to human papillomavirus, children receive 2 shots, and the second shot is given 6 months after the first shot. Therefore, before vaccination, the dosage and frequency of vaccination need to be determined accordingly according to different vaccines.
3. Vaccination time
The time of vaccination is one of the key factors affecting the effectiveness of vaccination. Vaccination too early or too late will affect the effectiveness of the vaccine. For example, the Japanese encephalitis vaccine is mainly given to infants and children over 6 months old, while the yellow fever vaccine is mainly given to people who are going to affected areas, and should be given 10-14 days before departure. Therefore, before vaccination, you need to understand the vaccination time requirements of different vaccines and strictly follow the vaccination time requirements.
4. Vaccine precautions
When getting vaccinated, you need to understand and follow some vaccine precautions. For example, you need to avoid contact with pregnant women when getting the chickenpox vaccine, and you also need to pay attention to the site of the vaccine when you get the human papillomavirus vaccine. In addition, it is normal to experience some reactions such as fever, headache, and muscle pain after vaccination. However, if abnormal reactions such as shortness of breath and fast heartbeat occur, you should seek medical treatment in time.
After summarizing the above four aspects, we can conclude that the six recommended second-category vaccines are: rotavirus vaccine, influenza vaccine, chickenpox vaccine, hepatitis B vaccine, human papillomavirus vaccine and yellow fever vaccine. When vaccinating, it is necessary to consider and comply with the corresponding regulations based on factors such as the vaccination target, vaccination dose and frequency, vaccination time, and vaccine precautions to ensure vaccination effectiveness and health and safety.
