Pneumonia vaccine adverse reactions

Pneumonia vaccine, as the name suggests, is a vaccine used to prevent the human body from being infected with pneumonia. In our lives, many people still get vaccinated against pneumonia, which is also for their own health. Getting vaccinated against pneumonia is very necessary for the health of the general public. After all, the incidence of pneumonia is still very high, so the general public is at risk of getting the disease. However, many people will experience some adverse reactions after receiving the pneumonia vaccine.

In fact, the adverse reactions mentioned above after people receive the pneumonia vaccine are relatively common. This is also because the physical constitutions of most people are different. Therefore, after everyone has received the pneumonia vaccine, if some adverse reactions occur in the body, they must go to the hospital for examination in time, and treatment is required if necessary.

A total of 592 subjects were vaccinated with this product in the domestic registered clinical trial. The safety information after combined analysis of local reactions, systemic reactions and adverse events related to this vaccine is summarized as follows:

When this vaccine was administered separately from DTaP (297 cases), the most common systemic adverse reactions were fever (>37.5°C) and sleep disruption (26.60%), irritability (21.89%), decreased appetite (15.49%) and diarrhea (14.81%). Most symptoms were mild, with 2 cases (0.79%) experiencing body temperature >39°C. Local adverse reactions at the injection site included erythema (11.11%), nodules (7.74%) and pain (9.09%), with erythema and nodules with a diameter >2.5 cm accounting for 1%. The incidence of the above adverse reactions was highest after the first dose and decreased to varying degrees after the second and third doses.

When this vaccine was administered simultaneously with DTaP (295 cases), the most common systemic adverse reactions were fever (>37.5°C) (28.81%), sleep disruption (26.78%), irritability (26.44%), diarrhea (24.07%) and decreased appetite (16.61%). Most symptoms were mild, with body temperature >39°C in 4 cases (1.36%). Local adverse reactions at the injection site included erythema (10.85%), nodules (7.46%) and pain (11.86%), with erythema and nodules with a diameter of ＞2.5cm accounting for 1%. The above adverse reactions also occur most frequently after the first dose, and to varying degrees after the second and third doses.

Adverse reactions in various body systems: Local reactions at the injection site are rare: rash, urticaria or urticarial rash Blood and lymphatic system. Very rare: lymphadenitis confined to the injection site. Immune system reactions Rare: anaphylactic/anaphylactoid reactions including shock, angioedema, dyspnea, bronchospasm, facial edema.

Therefore, through the detailed introduction in the above article, we have learned about some common adverse reactions after pneumonia vaccination. In fact, there are still many adverse reactions after receiving the pneumonia vaccine, but they vary from person to person. They are generally manifested as: shock, difficulty breathing, facial edema, etc. Although these adverse reactions are normal, we must check and treat them in time after such situations occur.
