A study carried out by the Institute of Infectology Emílio Ribas of São Paulo, a reference in the care of infectious diseases in the state, revealed that about 90% of patients admitted to the hospital with covid-19, between January and the first half of September this year, did not had completed their vaccination schedule. Of the 1,172 patients surveyed, 1,034 were not fully immunized.
According to infectologist Jamal Suleiman, who released the data at a press conference held on Tuesday (26), of these 1,172 cases identified in the survey, 274 died. Of this total, 237 had not received any dose of the vaccine, 21 only the first dose and 16 had received both.
Although the data has yet to undergo statistical treatment, the numbers reinforce evidence already revealed in other research on the effectiveness of vaccination in reducing hospitalizations and deaths. “We can’t protect them all [as pessoas] – Suleiman said – “but the maximum protection, the maximum number of individuals.”

Boost in immunity
talking to G1, the physician Ana Freitas Ribeiro, also from Hospital Emílio Ribas, highlighted that the results of the study can be useful for those people who still have some kind of doubt about taking their vaccine or not, or who are on a late schedule. For the health professional, “he took the first one, there’s no second, there’s no reinforcement – they look for the health units and have their vaccinations.”
Talking about the booster dose for the elderly and health professionals, who were the first to be vaccinated in the country, Suleiman emphasizes that, to avoid hospital admissions and deaths from covid-19, “it is essential that people go to health centers to receive these immunizing agents.”
In addition to the reinforcement being crucial given the emergence of more than 25 sublineages of the Delta variant in the country, the infectologist draws attention to the so-called phenomenon of immunosenescence. As a consequence of aging, these immunological changes present in the body of the elderly cause a higher susceptibility to respiratory infections, cancer, and autoimmune and cardiovascular diseases, in addition to a natural fall in the protection of vaccines after six months.
