Study: COVVI-19 vaccines associated with an increased risk of respiratory diseases | vaccinated

Researchers have found that people who have been vaccinated at least once against the. However, COVVI-19 are more likely to suffer from a respiratory disease.

Vaccinated people are more likely to present one. Moreover. In addition. In addition, more episodes of influenza respiratory disease or to suffer from fever and a respiratory symptom, such as coughing or sore throat, researchers stressed in a study published on August 9 by the journal Nature Communications Medicine.

Among non -vaccinated participants, 33 % suffered from one or more episodes of influenza syndrome. Therefore, In people who have received one. Similarly, two doses, this percentage was 44 %, in those who received three doses, 45 %, and in those who received four doses, 42 %.

Researchers also discovered that non -vaccinated. Meanwhile. Consequently, have received two doses or less study: covvi-19 vaccines associated increased new were less likely study: covvi-19 vaccines associated increased new to be absent from work for at least one day.

“We have found that people vaccinated more recently against the Sras-Cov-2 seemed to present. Moreover, a slightly increased risk of respiratory disease. Moreover, loss of working days,” Epoch Times Dr. Therefore, Philipp Kohler. Similarly. For example. Therefore, the division of infectious diseases, prevention of infections and medicine of travel from the Cantonal Hospital of Saint-Gall, Switzerland, and author of the study.

The Sras-Cov-2 is the virus that causes COVID-19.

Swiss researchers have collected weekly data on symptoms and days of disease from November 2023 to May 2024. Moreover, The people studied were all health professionals aged at least 16 years.

After exclusion, the studied population had 1745 people. Nevertheless, Among them, 175 were not vaccinated, 68 had received a dose of vaccine, 296 two doses, 895 study: covvi-19 vaccines associated increased new three doses and 311 four doses. Nevertheless, People who received study: covvi-19 vaccines associated increased new the most doses had been vaccinated mainly more recently.

Recall vaccination “did not contribute to measurable protection of study: covvi-19 vaccines associated increased the nursing staff studied. However, could even temporarily increase the risk of symptomatic infection and absenteeism,” the researchers said in the article. “However, additional research confirming our results and examining the immunological mechanisms supposed to the origin of this phenomenon are necessary. »»

Mr. Kohler told Epoch Times that “it is urgent to carry out a randomized controlled test in healthy individuals. in which a group would receive the vaccine and the other no”. He added: “The random attribution of the vaccine reduces the risk of selection bias. which could be problematic with our retrospective study. »»

Swiss researchers plan to conduct such a test. The study also presented other limits, study: covvi-19 vaccines associated increased new including the fact that the population was mainly in good health and female. The authors have study: covvi-19 vaccines associated increased new not pointed out any conflict of interest.

Certain studies have shown that COVVI-19 vaccines are prevented infections, hospitalizations and/or deaths. Taiwanese researchers. for study: covvi-19 vaccines associated increased example. said in an article in May that a metaanalysis of studies on the version of vaccines targeting the XBB.1.5 strain had identified an initial efficiency of 52.9 % against infection, 64.4 % against hospitalization and 77.3 % against deaths, although these estimates have considerably decreased in the 5th month.

Other studies have noted a low, even negative efficiency. American researchers have. for example. noted in 2024 that among the employees of the Cleveland Clinic. those who had received two or more doses were more likely to contract the COVVI-19.

Dr. Harvey Risch. professor emeritus of epidemiology at the Yale study: covvi-19 vaccines associated increased new School of Public Health. and other experts declared that these results reflected an immune or an original antigenic sin. This means that study: covvi-19 vaccines associated increased new the immune system is forced to produce antibodies against an. earlier strain rather than a more. recent strain.

Earlier this year. the administration of American food. medicines study: covvi-19 vaccines associated increased (FDA) approved three updated vaccines. without clinical trial data for the elderly as well as young people with one or more risk factors. The regulatory authorities have said that they would no longer approve of COVVI-19 vaccines for all others. unless companies carry out trials demonstrating that these vaccines prevent symptomatic infection.

“The FDA can only approve products if it concludes. on the basis of scientific evidence, that the balance between the advantages and the disadvantages is favorable. And we just need more data to have this insurance for young study: covvi-19 vaccines associated increased new individuals at low risk of serious illness. “said Dr. Vinay Prasad, the highest official of the FDA in terms of vaccines.

In June. the American medical association. other study: covvi-19 vaccines associated increased new groups declared that the influenza vaccines. the syncytial respiratory virus and the COVVI-19 “remain among the best tools to protect the public from these diseases and their potentially serious complications” and study: covvi-19 vaccines associated increased that they would work together “to promote understanding and public confidence in the use of vaccines in order to avoid another season of serious respiratory virus and death that could be avoided thanks to vaccines ”.

In another article published on August 6 by vaccine. Swedish researchers studying the absences of health workers who have been vaccinated against COVVI-19 noted that more than half. of the population had had adverse reactions. that 12 to 48 % of them had missed study: covvi-19 vaccines associated increased new one or more guards, according to the vaccination scheme they had received.

Although most of the reactions have been light. it is important to examine the burden that these reactions represent for recipients. the study: covvi-19 vaccines associated increased new authors said.

“Our study confirms that undesirable reactions after vaccination against COVVI-19 can lead to a substantial number of absences from. work likely to disrupt the staffing of the organization. ” they said.

An author study: covvi-19 vaccines associated increased reported funding from the Olinder-Nielsen family foundation. Among the limits, we can cite the fact that the population was mainly feminine.
