There's a silver lining to everything, folks — even the occasional bout of blood clots or facial paralysis.

People who reported experiencing side effects to the Pfizer/BioNTech and Moderna Covid-19 vaccines such as fever, chills or muscle pain tended to have a greater antibody response following vaccination, according to new research.

Having such symptoms after vaccination is associated with greater antibody responses compared with having only pain or rash at the injection site or no symptoms at all, suggests the paper published Friday in the journalJAMA Network Open.

"In conclusion, these findings support reframing post-vaccination symptoms as signals of vaccine effectiveness and reinforce guidelines for vaccine boosters in older adults," the researchers – from Columbia University in New York, University of Vermont and Boston University – wrote in their paper.
