Summary
This trial is being conducted to see if people who have had bad reactions to COVID-19 vaccines in the past can safely have another dose, or if people with a history of allergies can safely have the vaccine at all.
Who is the study for?
This trial is for adults over 18 who've had adverse reactions to previous mRNA COVID-19 vaccines, allergic reactions without prior vaccination, or issues after a natural COVID infection. They must not be pregnant, immunocompromised, have immune disorders, recent COVID-19 infections or treatments with antibody agents.
What is being tested?
The study tests the safety of an additional dose of Pfizer-BioNTech or Moderna bivalent mRNA COVID-19 vaccine in those with past adverse reactions to vaccines or 'long COVID', and initial doses in those with a history of allergies.
What are the potential side effects?
Potential side effects may include typical vaccine-related responses such as soreness at injection site, fatigue, headache, muscle pain, chills, fever and nausea. Severe allergic reactions are rare but will be closely monitored.

Awards & Highlights
No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.
Pivotal Trial
The final step before approval, pivotal trials feature drugs that have already shown basic safety & efficacy.
Drug Has Already Been Approved
