People with histories of severe (or even life-threatening) allergic reactions to any medications should not take the Moderna Coid-19 vaccine – a recommendation from both doctors or Moderna’s scientists. Whether that allergy is medical or specific to vaccines, it does not matter.
Older persons with a low life-expectancy (less than 3 months) should be individually assessed by a healthcare professional. People under the age of 18 should also not be given this vaccine, until more is known about its effect on this age group.
