Would third dose of COVID-19 vaccine help people with suppressed immune systems?

Immune response was boosted in transplant patients who got a third shot of vaccine

They could be among the first to request a third dose of COVID-19 vaccine — people whose immune systems are so impaired that two doses don’t offer them protection from the coronavirus. It’s a serious problem that impacts millions of people with diabetes, cancer, rheumatoid arthritis or who have had organ transplants. Most of them share that one weak spot — immune systems that are compromised by drugs or radiation therapy, or everyday medicines.

Studies show that COVID-19 vaccines may not prompt the production of sufficient antibodies in people who are immunocompromised. But, according to one study, when 30 transplant patients got a third shot of vaccine, their immune response was boosted. If Americans don’t get vaccinated in enough numbers to provide herd immunity, could a third shot of the vaccine prove the charm for people with suppressed immune systems?
