It starts on September 20 with transplanted and immunocompromised. According to the circular of the Ministry of Health, the “booster” dose will instead be administered subsequently in favor of other groups including fragile and higher risk for occupational exposure such as doctors and nurses
The third doses of the anti-Covid vaccine will start on 20 September. It will start with transplant recipients and immunosuppressed, while other target categories – such as health care and frail subjects – will be defined, “without prejudice to the priority of achieving high vaccination coverage with the completion of currently authorized cycles”. This in summary is the content of the circular with which the Ministry of Health gives preliminary indications on the methods of administering “additional doses” and “booster doses”, explaining the difference between the two concepts and reiterating that “at the moment, according to the indications of the Cts, the administration of the additional dose in transplanted and immunocompromised subjects is considered a priority “.
Third dose at 28 days, we start from transplanted
The additional dose of Covid vaccine should be administered at least 28 days after the last dose. And we mean an additional dose to complete the primary vaccination course, to achieve an adequate level of immune response. The “booster” dose, unlike the additional one, is administered in order to maintain or restore an adequate level of immune response over time. And it will be administered at least six months after the last dose in favor of additional groups including fragile and higher risk for occupational exposure such as doctors and nurses.
Third additional dose to 10 patient categories
There are 10 categories of patients who will be able to receive a third “additional” dose of the anti-Covid vaccine: solid organ transplant recipients in immunosuppressive therapy; hematopoietic stem cell transplantation; waiting for organ transplant; T cell based therapies; oncological pathology; primary immunodeficiencies; secondary immunodeficiencies; dialysis and severe chronic renal failure; previous splenectomy; AIDS. This was established by the circular of the Ministry of Health. Any of the 2 authorized mRNA vaccines can be used as an additional dose: Pfizer in subjects 12 years of age or older and Moderna 18 years and older.
