Are My Symptoms Due to COVID-19 or the Vaccine?

The Pfizer COVID-19 mRNA vaccine received Emergency Utilization Authorization by the FDA and CDC last week and is being administered to health care workers and seniors in senior facilities as I write. The process began overseas in the United Kingdom last week.

Many of the recipients of the first of two vaccinations are experiencing symptoms as their immune system reacts to the vaccine and hopefully builds antibodies and immunity. They are experiencing fever, fatigue, headaches, chills, myalgias and arthralgias.  Many of these symptoms are identical to the symptom’s individuals infected with COVID-19 experience yet these healthcare workers are expected to take some Tylenol or aspirin and head back to work caring for patients.  How exactly are they expected to distinguish between being infected with “the Rona” virus or just experiencing mild side effects of the vaccine?    

David Kuhar, MD, of the CDC’s COVID-19 Response Healthcare Infection Control Team suggests health care workers need to use their clinical judgement.  They need to assess whether they believe they were exposed to the virus in the previous 14 days?  He emphasized that in clinical trials, these adverse symptoms resolved within 3 days of vaccination and 2 days of the onset of symptoms. If the symptoms last any longer, he believes the healthcare workers need to be evaluated for a COVID-19 infection.  He stressed that the vaccination will not produce a positive COVID-19 antigen test response. It additionally should not produce shortness of breath and loss of taste and smell sensations. 

If you experience those symptoms or have your symptoms for more than two days, then you need to go to a COVID-19 test site and be tested.  The CDC has set up a communication system for those vaccinated called V-safe.  It is an app for your smartphone or tablet that allows you to communicate your symptoms and concerns with the CDC after you receive the vaccine.  When you are vaccinated at a test site, you are provided the information you need to register and participate in this V-safe monitoring program.  The information gathered on this smartphone app will allow the CDC to continue to monitor the safety of the vaccines being administered.
