DHA to administer third dose of Pfizer-BioNTech Covid-19 vaccine to residents with weakened immune systems

The third dose of the Pfizer Covid-19 vaccine helps increase immunity in vulnerable people, including immunocompromised patients, according to doctors in the United Arab Emirates.

Dr Adil Sajwani, specialist in family medicine at Fakeeh University Hospital said: “It is evident that the Pfizer Covid-19 vaccine has a good response in the fight against the coronavirus, and the third dose is recommended for people having a medical history. “

Patients on cancer treatment and immunotherapy and those with a weak immune response will have weaker immunity against the coronavirus and therefore may require a booster to increase immunity against Covid-19, he added.

The Dubai Health Authority (DHA) has announced that it will begin administering the third dose of the Pfizer-BioNTech Covid-19 vaccine to residents with weakened immune systems.

Dr Vrishali Rohankar, General Practitioner and Medical Director, Aster Clinic, Sheikh Zayed Road, said: “The third dose of the vaccine is required for vulnerable categories such as patients with HIV infection, those undergoing chemotherapy for cancer. and organ or stem cell transplant recipients. “

These patients may have reduced immunity and less protection against the coronavirus compared to normal people, Rohankar added. The durability of the antibody response decreases in them and there is the challenge of exposure to new variants of the virus.

Medicos said the antibody titer would last longer in the general population and in people with healthy immune systems.

To confirm their eligibility for the third dose, residents will need to make a consultation appointment with a DHA family physician or request a telemedicine consultation by calling 800 342.

A detailed medical evaluation by a DHA physician is required before approving the third dose of vaccine and the antibody titer will also be checked.

DHA had previously said that people who are fully vaccinated and do not have an immune disease would not need to take an extra dose of the vaccine at this time.

In some cases, even patients with immune-related illnesses might not need a third dose, he said.
