Coughing non-stop in spring? Respiratory disease vaccines “boost in supply and demand”


Coughing non-stop in spring? Or maybe it was the flu. Recently, monitoring data from the 2024 Weekly Influenza Surveillance Report released by the Chinese Center for Disease Control and Prevention shows that the current national influenza epidemic is still at a high level, and the proportion of influenza B in the country has increased for 9 consecutive weeks. Experts remind that during this period, in addition to preventing influenza, middle-aged and elderly people and patients with chronic respiratory diseases, chronic cardiovascular diseases, and diabetes must also pay attention to preventing pneumococcal diseases.

Coexistence of influenza, pneumococcal infection, and mycoplasma infection

“We have observed that current respiratory diseases are more common including influenza, pneumococcus, mycoplasma infection, etc.” Lu Jianyun, director of the Guangzhou Baiyun District Center for Disease Control and Prevention, said that winter and spring have always been the period of high incidence of respiratory diseases. After the holidays, with the return to work and school, the flow of people will also increase. Coupled with the repeated effects of temperature, citizens will be more susceptible to respiratory diseases.

“Judging from the recent outpatient situation, there are actually obvious peaks in consultations before and after the holidays, and with the gradual upward trend, the number of patients is currently very large.” said Guangdong Prayer Hospital, director of the vaccination department of the internal medicine outpatient department and deputy director of the infectious diseases department. Director Wang Yinmeng reminded that in addition to preventing influenza, we must also prevent pneumococcal infection. She explained that pneumococci are gram-positive cocci with more than 90 serotypes, and the main pathogenic types are probably more than 20 serotypes. Pneumococci are generally spread from person to person through respiratory droplets. It is an opportunistic pathogenic bacteria that often “lurks” in the human nasopharynx. It usually does not cause disease, but it will take advantage of it when the body’s immunity is weakened, such as when respiratory viruses such as influenza are infected. Pneumococcal diseases caused by pneumococcal infection include pneumonia, sinusitis, otitis media, endocarditis, meningitis, bacteremia, etc.

Industry data shows that the economic burden and disease burden of chronically ill elderly people over 65 years old increase by more than 10 times after they contract pneumonia. “Middle-aged and elderly people and patients with chronic respiratory diseases, chronic cardiovascular diseases, and diabetes are all susceptible to pneumococcal infection. In addition to the risk of pneumococcal disease itself, this group of people are more susceptible to acute pneumonia in the process. Among them, the original basic diseases that are relatively well controlled may be acutely exacerbated, for example, blood pressure will increase, and even the risk of death will increase.” Wang Yinmeng said.

Vaccines for respiratory diseases on the market are “booming in supply and demand”

It is reported that the supply and demand of vaccine products for respiratory diseases on the market are booming. “As far as Baiyun District is concerned, the citizens are provided with several vaccines against respiratory diseases, such as the three immunization program vaccines provided by the state for free to school-age children: measles, mumps, diphtheria-tetanus-pertussis vaccine and meningococcal meningococcal vaccine, as well as Citizens can voluntarily receive influenza vaccine, COVID-19 vaccine, pneumococcal vaccine, chickenpox vaccine, and Haemophilus influenzae type b conjugate vaccine, mainly for children, at their own expense,” Lu Jianyun said.

Lu Jianyun suggested that the elderly and people with specific diseases (such as chronic cardiovascular disease, chronic lung disease or diabetes, people with functional or anatomical asplenia, people with compromised immune function, etc.) should receive the 23-valent pneumococcal vaccine. In his view, susceptible people can improve their ability to resist infection through vaccination and non-pharmaceutical measures. He also said that non-drug intervention methods also include “wash hands frequently, ventilate frequently”, pay attention to rest and nutrition, etc., and improve one’s immunity through various methods.

Wang Yinmeng introduced that there are currently one imported and four domestically produced 23-valent pneumococcal vaccines on the market, and citizens can choose according to their personal circumstances and the vaccine supply at local vaccination sites. Adults of this type of vaccine are vaccinated once and generally do not need to be re-vaccinated. For some patients with reduced immunity or immunodeficiency, they can be re-vaccinated after five years.

“The “Chinese Expert Recommendations on Influenza and Pneumococcal Vaccination for the Elderly” pointed out that combined vaccination of pneumococcal vaccine and influenza vaccine can benefit synergistically.” Wang Yinmeng said that before vaccination, all vaccines must first make sure that there is no acute infection and uncontrolled disease. Bad chronic illness. If you may have some chronic pneumonia daily but do not have any symptoms, it is a relatively stable state and does not affect vaccination.

It is understood that pneumococcal vaccination is the most effective way to prevent pneumococcal infection. Pneumococcal diseases are listed as one of the “very high priority” diseases to be prevented by vaccines by the World Health Organization (WHO).
