According to experts, people with a weakened immune system may need three or four vaccinations to get adequate protection from the coronavirus.
Hospitals are studying the effects of vaccines on people with a reduced immune response as a result of a genetic condition, a disease such as leukemia, or a drug that must be taken after a transplant.
Bram Goorhuis, coordinator of the coronavirus division at Amsterdam UMC, said about 50,000 people in the Netherlands may need additional injections of the vaccine to increase their resistance to the virus.
“We want to make sure we provide adequate protection for these patients as well,” Goorhuis told AD.nl. “Maybe more vaccines will work.”
France has already decided to give a third dose to patients with weakened immunity. The first jab protected only 17% and the second vaccine increased to 45%.
So far, the Dutch Ministry of Health has not answered the question from Dutchnews.nl as to whether there are plans to introduce a third vaccination.
Currently, eight studies are being conducted nationwide on the effectiveness of vaccines in patients with low or impaired immune response. A study conducted at Groningen examined the effects on 500 cancer patients receiving chemotherapy or immunotherapy.
“We want to find out which patients do not respond well, which can vary by age, type of cancer, and type of treatment,” said Groningen UMC’s Oncology Department. Professor Liesbeth de Vries said.
