Rare side effects after Moderna

  •  severe allergic reaction (anaphylaxis),
  • heart inflammation (myocarditis and pericarditis)

Heart Inflammation (myocarditis and percarditis)

See the Government’s  guidance on myocarditis and pericarditis after mRNA COVID-19 vaccines (includiing a comparison of Pfizer and Moderna)

The Melbourne Vaccine Education Centre has a page on myocarditis and pericarditis that includes an explanatory video.

You should speak to your GP, immunisation specialist service or cardiologist about the best timing of vaccination and whether any additional precautions are recommended:

  • You have had myocarditis or pericarditis within the  last 3 months
  • You have acute rheumatic fever or acute rheumatic heart disease (i.e., with evidence of active inflammation)
  • Acute decompensated heart failure (worsening of heart failure symptoms)

Dose Injection technique cause myocarditis?

ATAGI does not consider injection technique to cause adverse events because most myocarditis cases occur after the second dose, and if accidentally injecting into a blood vessel was a factor, cases would occur equally after both doses.

People who should not have the Moderna vaccine

It’s not recommended that you have the Moderna vaccine if you have had:

  • severe allergic reaction (anaphylaxis) to a previous dose of an mRNA COVID19 vaccine (Moderna or Pfizer)
  • anaphylaxis after exposure to any component of the vaccine, including polyethylene glycol (PEG)
  • myocarditis and/or pericarditis attributed to a previous dose of an mRNA COVID-19 vaccine (Moderna or Pfizer)
  • any other serious adverse event, that following review by an experienced immunisation provider or medical specialist was attributed to a previous dose of Moderna or Pfizer vaccine.

I have heard about possible allergies. What non-active ingredients are included in the Moderna vaccine ?

None of the vaccine ingredients are of human or animal origin and there are no food, latex or gelatin in the COVID-19 vaccines that are currently available. If individuals have had an allergic reaction to other vaccines in the past, it does not mean that they will also be allergic to the COVID-19 vaccines (Australasian Society of Clinical Immunology and Allergy [ASCIA], 2021).

Patients with allergies to the ingredients  in the vaccination will need to discuss  COVID19 vaccination with their doctor.
