The Covid vaccine reduces the risk and lengthens the time to new infection in reinfected patients.
One dose vaccination only Covid vaccine reduces risk of reinfection by 65 percentAccording to a study conducted by a team of microbiologists from the University Teaching Hospital of Valladolid and the WHO Influenza Center, this percentage increases to 83 and 95 percent when using the full treatment regimen (two doses) and booster vaccination (three doses), respectively. in Valladolid to analyze hybrid immunity from infection and puncture.
After analyzing the records of 746 patients who were reinfected between 2020 and 2022, the work, carried out with the help of Universidad Juan Carlos, concluded that the time to reinfection was “significantly longer” among those vaccinated than they found the time that it took them to become infected with the virus again reached a high level. Moreover, if revaccination is administered 6 months after the first dose.
A result that understands that today would be more noticeable, since during the period when the study was carried out, different variants were encountered – original, alpha-delta and omicron. “It is possible that current vaccines provide greater risk reduction,” the Health Ministry said in a statement.
In any case, “as with influenza viruses, this beta-coronavirus is evolving and vaccines need to be updated regularly,” they add, pointing to “vaccine fatigue” in the wake of the pandemic, which has led to “declining adherence to both anti-COVID, so do vaccines.” -19 and flu shots.”
Given the results, the data collected in the study highlight “the importance of maintaining a vaccination strategy against SARS-CoV-2, especially in vulnerable patients,” they conclude from Health.
