What side effects are patients asking about?
Prevnar 20, also known as pneumococcal conjugate vaccine, is a vaccine used to protect against Streptococcus pneumoniae (pneumococcus), a bacteria that can cause pneumonia and other infections [1]. Like all vaccines, Prevnar 20 can cause side effects, some of which can be serious.
Common side effects:
The most common side effects of Prevnar 20 reported in clinical trials include [2]:
* Pain, redness, or swelling at the injection site (up to 50% of participants)
* Fever (up to 25% of participants)
* Headache (up to 20% of participants)
* Fatigue (up to 15% of participants)
* Muscle pain (up to 10% of participants)
* Chills (up to 10% of participants)
Less common side effects:
More serious side effects, such as allergic reactions, have been reported in a small number of participants [2]. These include:
* Allergic reactions, such as hives, itching, or difficulty breathing
* Swelling of the face or throat
* Increased blood pressure
* Decreased platelet count (a condition known as thrombocytopenia)
Very rare side effects:
In rare cases, the vaccine has been linked to more serious side effects, including:
* High fever (above 102°F): This can occur in up to 1 in 100,000 participants (Source: [3])
* Seizures: This can occur in up to 1 in 50,000 participants (Source: [3])
* Guillain-Barré Syndrome (GBS): This is a rare neurological disorder that can occur in up to 1 in 100,000 participants (Source: [3])
Precautions:
It's essential to note that Prevnar 20 should not be given to people with a history of severe allergic reactions, such as anaphylaxis, or those with weakened immune systems, including people with HIV/AIDS, cancer, or taking immunosuppressive medications [2].
What should I do if I experience side effects?
If you experience any side effects after receiving Prevnar 20, contact your healthcare provider immediately. In the event of a severe allergic reaction, seek medical attention right away.
