Active Monitoring: Post Vaccine Symptom Check

Introduction

The Post Vaccine Symptom Check Survey is an additional way to report reactions to the Pfizer COVID-19 vaccine (Comirnaty).

The information from the Post Vaccine Symptom Check survey supports ongoing safety monitoring of the Pfizer COVID-19 vaccine (Comirnaty) used in New Zealand. Find out more about how we are monitoring COVID-19 vaccine safety.

The data collected from these PVSC surveys has not raised any new safety concerns with the Pfizer vaccine.

How it works

Up to 25% of the population in New Zealand who receive a Pfizer COVID-19 booster vaccine and up to 25% of the population in New Zealand who receive a paediatric Pfizer COVID-19 vaccine will be randomly selected to participate in the survey in the days following their appointments. If you report a reaction, you will be asked to further describe what that reaction was.

Any information you provide in the survey will not be followed up on directly, it will be used for confirming the safety of the vaccine.

Taking the survey is optional. If you do not want to participate in the survey, you do not have to give a reason, and it will not affect the care you receive.

If you decide to take part, but change your mind later, you can opt out of participating in the survey at any time.

If you do not receive a text to be part of the survey, but you or your child(ren) experience a reaction, you can still report to the Centre for Adverse Reactions Monitoring (CARM).

You don’t need to be a health professional to submit a report and you don’t need to be certain that the reaction was caused by the vaccine.

If you are concerned about any reactions you or your child experiences or if you or your child are unwell please contact your GP, healthcare provider or Healthline on 0800 358 5453.

There are currently two active Post Vaccine Symptom Check survey campaigns:

Booster Pfizer COVID-19 vaccine Campaign (Adults)

If you are selected, you will receive a text message to the cell phone number provided as part of your vaccination journey.

  • Text 1: Sent 6 days after your booster dose of your COVID-19 vaccine

This text will ask you if you have had a side effect after your vaccine. You can respond with “NO” or “YES”. If you respond “YES”, you will receive a follow up text which will link you to a survey asking you about this reaction. If you do not want to receive these text messages anymore, simply respond “STOP”.

Child Pfizer COVID-19 vaccine Campaign

If your child is selected, you will receive a text message to the cell phone number you provided as part of their vaccination journey. The text message will specify the child that the survey pertains to.

  • Text 1: Sent 6 days after your child’s first dose of their COVID-19 vaccine
  • Text 2: Sent 6 days after your child’s second dose of their COVID-19 vaccine

Text 1 and Text 2 will ask you if your child had a side effect after their vaccine. You can respond with “NO” or “YES”. If you respond “YES”, you will receive a follow up text which will link you to a survey asking about their reaction. If you do not want to receive these text messages anymore, simply respond “STOP”.

Note: if you are the parent/guardian of multiple children, you might only be invited to complete a survey for one of your children. It is important to only complete the survey as it relates to the child mentioned. If you would like to report a side effect for your other children, you can do that online here. or talk to your healthcare professional.

Side effects of the Pfizer COVID-19 vaccine

Side effects of the Pfizer COVID-19 vaccine can occur immediately or in the days after your vaccine.

Common reactions may include:

  • Pain, redness or swelling at or near the injection site

  • Fatigue/tiredness
  • Fever/high temperature
  • Chills
  • Nausea

Other less common symptoms may include:

  • Vomiting
  • Racing heart

The side effects of vaccination in children and young adults are similar to those seen in adults. These side effects are generally mild and should only last 1 or 2 days.

The most common side effects are:

  • a sore arm – you can put a cold cloth or ice pack on it to feel better
  • a headache
  • feeling tired
  • feeling feverish or sweaty
  • nausea
  • aching muscles

It’s important that anyone with an abnormal/racing heartbeat, trouble breathing, or chest tightness/discomfort in the days after vaccination seeks medical attention promptly.

You can find more information on side effects on the Ministry of Health website.

See the consumer medicine information for the full list of side effects for the Adult and Paediatric (Child) Pfizer COVID-19 vaccines.

If you or your child are concerned about your health, please contact your GP or healthcare provider. You can also call Healthline for free on 0800 358 5453.

How to report a reaction if you don’t receive a text message

We are monitoring reports of serious and non-serious reactions after the Pfizer COVID-19 vaccine (Comirnaty), the AstraZeneca COVID-19 vaccine (Vaxzevria), and the Novavax COVID-19 vaccine (Nuvaxovid) through reports to CARM.

If you don’t receive a text message for the Post Vaccine Symptom Check, it’s still important that you report any reactions to the vaccination.

You can submit a report on the CARM website or by calling the COVID-19 Vaccination Healthline for free at 0800 358 5453.
