The World Health Organisation’s vaccine advisory group on Monday recommended immunocompromised people should have an additional dose of all Covid-19 vaccines authorised by the WHO.
“Moderately and severely immunocompromised persons should be offered an additional dose…since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe Covid-19 disease,” the UN health agency’s Strategic Advisory Group of Experts on Immunisation said.

In August, America’s Food and Drug Administration (FDA) amended the emergency use authorisations (EUA) for Pfizer-BioNTech and Moderna to allow a third dose of their COVID-19 vaccines for certain immunocompromised people.
The list for those who are immunocompromised and are eligible for a third dose include solid organ transplant recipients and those with conditions that give them an equally reduced ability to fight infections and other diseases.
According to the FDA report, a third dose of the Pfizer or Moderna vaccines may increase protection in this vulnerable population.
