Hello, thank you for reaching out to us regarding your issue.
For your information, based on the latest research, paracetamol does not have any effect on the Covid-19 vaccine post-vaccination. In fact, it has been recommended as a therapy for mild symptoms of fever and pain and also for symptomatic Covid-19 patients. You may take paracetamol after vaccination to help with some of the side effects of the vaccine. However, taking paracetamol before vaccination is not recommended because it is not known how painkillers may affect how well the vaccine works.
We hope our answer has been helpful. If you wish to enquire further, please consult our online doctors.
