Pfizer (finally) releases the list of side effects of its vaccines.

Less Common but Known Reactions

Some additional side effects have also been documented, such as:

• Nausea or dizziness
• Swollen lymph nodes
• Decreased appetite
• Mild allergic reactions like rash or itching

These are still generally short-lived and manageable.

Rare but Serious Side Effects

Health agencies have identified a few rare but more serious risks, including:

• Severe allergic reactions (anaphylaxis)
• Myocarditis and pericarditis (inflammation of the heart)

These events are uncommon and are monitored closely by global health systems.

Importantly, studies show that the risk of complications from COVID-19 infection itself is often higher than the risk from vaccination.
