Safety monitoring of COVID-19 vaccines and reporting of side effects

Find out how COVID-19 vaccines are being monitored to make sure they're safe, and how to report side effects.

How vaccine safety is monitored

The safety of all medicines approved for use in New Zealand is checked by the New Zealand Medicines and Medical Devices Safety Authority (Medsafe).

Medsafe will continually review any COVID-19 vaccines being used and take appropriate action if any risks are identified.

Medsafe uses information from many different sources to check vaccine safety including:        

  • clinical and epidemiological studies        
  • case reports      
  • published literature        
  • pharmaceutical companies       
  • other regulatory authorities.

How side effects are reported

The Centre for Adverse Reactions Monitoring (CARM) is a database of information about adverse reactions (side effects) to medicines and vaccines in New Zealand.

CARM monitors this information to identify any issues to help with the safe use and prescribing of medicines. 

Reporting your side effects will contribute to the data being collected globally, and help identify patterns in New Zealand and any potential safety issues.
