Pneumonia vaccine can be administered in any season of the year, and those who are eligible for vaccination should receive it as early as possible to achieve better results. Currently, there are two types of vaccines commonly used to prevent pneumonia, the 13-valent pneumonia vaccine and the 23-valent pneumonia vaccine, which are targeted at different groups. 13-valent pneumonia vaccine is suitable for infants and young children between 6 weeks and 15 months of age, while the 23-valent pneumonia vaccine is suitable for children over 2 years of age and adults. The optimal vaccination program for the 13-valent pneumonia vaccine is to receive one injection at 2, 4 and 6 months of age, and a booster injection at 10 to 15 months of age to maximize the protective effect. The 23-valent pneumonia vaccine is commonly used in elderly people over 65 years of age (high-risk groups), and those who meet all the indications for vaccination should be vaccinated as early as possible to benefit from the vaccine as soon as possible. The vaccine should be administered as early as possible for the benefit of those who meet all the indications for vaccination.
