Lymphadenopathy most common adverse event following COVID-19 boosters: TGA

Swollen lymph nodes are the most common adverse reaction to COVID-19 booster shots reported to the TGA so far.
The reaction is listed in the PI for both Comirnaty and Spikevax.
Trials suggest it occurs after 5-10% of third or booster doses compared with fewer than 1% of first or second doses, the watchdog said in its latest vaccine safety report.
It has warned patients to seek medical care if lymphadenopathy persists for “more than a few weeks” so that doctors can rule out other causes.
