The pneumococcal vaccine is a highly effective tool in preventing pneumococcal diseases, including severe conditions like pneumonia, meningitis, bacteremia, and sepsis. While the vaccine is generally safe, there have been reports of negative reactions, ranging from mild to severe. Mild side effects include fever, rash, and local reactions, while severe reactions can manifest as life-threatening allergic responses, including anaphylaxis. It is important to consult with a healthcare provider to determine individual vaccination plans and assess the risks of potential negative reactions.

What You'll Learn
Life-threatening allergic reactions
It is important to note that most side effects of the pneumonia vaccine are typically mild and temporary, lasting only a few days. However, in rare cases, individuals may experience severe allergic reactions. If you have concerns about the vaccine or are aware of any allergies or medical conditions that may increase your risk of an adverse reaction, it is crucial to consult your doctor before receiving the vaccine.
To identify a life-threatening allergic reaction, one should be aware of the signs and symptoms. As mentioned earlier, anaphylaxis is characterized by symptoms such as a rash, itching, a fast heartbeat, trouble breathing, and swelling in the face or throat. These symptoms can rapidly worsen and lead to anaphylactic shock, which is a medical emergency requiring immediate treatment.
Additionally, it is worth noting that certain factors may increase the risk of a severe allergic reaction. For example, individuals who have previously experienced a severe allergic reaction to a pneumococcal vaccine or any vaccine containing diphtheria toxoid are at a higher risk. Furthermore, those who are currently unwell, especially with a fever, may also be at an increased risk of adverse reactions. It is always advisable to consult a healthcare provider to determine the most appropriate vaccination plan based on individual health circumstances.
In summary, while life-threatening allergic reactions to the pneumonia vaccine are rare, they can occur. It is important to be aware of the signs and symptoms of anaphylaxis and seek immediate medical attention if necessary. Consulting a healthcare provider before vaccination is crucial, especially for individuals with known allergies or medical conditions. By taking these precautions, the benefits of the pneumonia vaccine in preventing pneumococcal diseases can be safely extended to those who are eligible.

Fever, leukocytosis, and large local reactions
In a clinical case series, five adult patients who received both the influenza vaccine and the PS23 vaccine exhibited a cellulitis-like reaction, fever, and leukocytosis within a few days of vaccination. Four of these patients received both vaccines in the same arm, while the fifth patient received them in opposite arms. This individual still exhibited local reactions in the arm that received the PS23 vaccine.
All five patients developed a fever greater than 101.5 °F within one day of vaccination, with the highest temperature recorded at 104.5 °F. They also experienced additional systemic symptoms such as rigors or vomiting, as well as erythema, edema, and warmth at the injection sites. The local reaction expanded beyond the immediate injection area by days 3–4 post-vaccination.
These symptoms, particularly the combination of prominent leukocytosis and systemic symptoms with severe local inflammation, have not been commonly described in adults following PS23 administration. This poses a diagnostic and management challenge for healthcare providers. It is important to distinguish this inflammatory response from a secondary infection, as unnecessary treatment may be administered if the robust inflammatory response to the vaccine is not recognized.
In conclusion, while rare, fever, leukocytosis, and large local reactions can occur after the pneumococcal polysaccharide vaccine (PS23). These reactions can be severe and may require medical attention. It is important for healthcare providers to be aware of these potential side effects to ensure proper diagnosis and management.

Severe redness and swelling
While the pneumonia vaccine is considered a safe and effective preventative measure against pneumonia, like any vaccine, it can cause side effects. Most side effects are mild and tend to go away on their own within a few days. However, severe redness and swelling at the injection site have been observed in a few cases.
A clinical case series reported five adult patients who received the influenza vaccine and the 23-valent pneumococcal polysaccharide vaccine (PS23) and experienced severe redness and swelling. This reaction was presumed to be cellulitis, and treatment was initiated accordingly. The patients had indications for the PS23 vaccine, including asthma, smoking, splenectomy, and preparation for immunosuppressive therapy in rheumatoid arthritis.
In another study, 21,000 adults aged 70 and older received the 13-valent pneumococcal conjugate vaccine (PCV13). Of these, 390 individuals (1.3%) reported injection site reactions to the Netherlands Pharmacovigilance Centre (LAREB), including 20 reports of extensive swelling of the vaccinated limb.
Furthermore, a series of eight adult studies with 19 cohorts examined the onset of injection site reactions (ISRs) over 14 days after administration of the PCV13 vaccine. The incidence of redness ranged from 2.3% to 19.6%, while swelling was observed in 0.9% to 10.8% of cases.
While severe redness and swelling are uncommon, they can occur as a reaction to the pneumonia vaccine. These side effects may be managed with over-the-counter anti-inflammatory medications such as ibuprofen. If the redness and swelling worsen or persist, it is important to seek medical advice.

Severe allergic reaction symptoms
Anaphylaxis is a severe allergic reaction that can be life-threatening and requires immediate medical attention. It can be caused by food, medicine, or insect stings, and symptoms usually start within minutes of exposure to an allergen. Sometimes, however, anaphylaxis can occur half an hour or longer after exposure, and in rare cases, it may be delayed for hours.
Symptoms of anaphylaxis include skin reactions such as hives, itching, and flushed or pale skin. There may also be constriction of the airways, a swollen tongue or throat, wheezing, and trouble breathing. Other symptoms include a fast heartbeat, abdominal pain, chest tightness, a feeling of doom or dread, and a drop in blood pressure.
If you or someone around you is experiencing anaphylaxis, call emergency services and go to the nearest emergency room, even if you have already administered epinephrine. It is also recommended to wear medical alert jewellery, such as a bracelet, to inform others of your allergy in case of an emergency.
It is important to note that allergic reactions can be unpredictable. Even if the first reaction is mild, the second reaction could be severe and life-threatening. Therefore, it is crucial to always have epinephrine on hand and to seek medical advice if you have had an allergic reaction or suspect that you may have had one.

Side effects in babies and children
Pneumococcal disease is a common infection in young children, but older adults are at greater risk of serious illness and death. The infection is caused by the bacterium Streptococcus pneumoniae, which can lead to severe conditions such as pneumonia, meningitis, bacteremia, sepsis, sinusitis, and ear infections. The pneumococcal vaccine is recommended for babies, older people, and those at higher risk of getting seriously ill from pneumococcal infections.
The CDC recommends that babies receive the PCV13 pneumococcal vaccine in four doses: at 2, 4, 6, and between 12 to 15 months. Common side effects in babies following the PCV13 vaccination include feeling a bit unwell and irritable. On rare occasions, babies may experience more serious side effects such as high fever, convulsions, or a skin rash. Contact your child's pediatrician if you notice any of these symptoms. You can give them children's paracetamol or ibuprofen to ease any symptoms, but always check with your pharmacist or doctor if you're unsure.
Young children may be at an increased risk of seizures caused by fever if the pneumococcal vaccine is administered at the same time as the inactivated influenza vaccine. It is important to discuss this with your healthcare provider before proceeding with the vaccination.
Serious allergic reactions (anaphylaxis) to the pneumococcal vaccine are very rare. Symptoms typically occur shortly after receiving the vaccine and may include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, or weakness. If you or your child experience any of these symptoms, seek immediate medical attention.
