A recent Hungarian study shows how effective vaccines are in Hungary. Among the authors of the study presenting the results are Cecília Müller and Miklós Kásler. They published their results in a prestigious international journal called Clinical Microbiology and Infection.
The study calculated with 3.7 million vaccinated people. Each of these individuals received a second vaccination. The effectiveness is shown by the fact that the infections and number of deaths registered among those vaccinated were compared with data of the unvaccinated control group, writes 24.hu. The obtained results were treated with statistical methods. Researchers also considered gender, age, and date of vaccination.
Among those completely vaccinated, protection against the infection is 68.7 to 88.7 per cent, depending on the vaccine.
Vaccine protection against mortality ranges from 87.5 to 97.5 per cent. Among 16 and 44-year-olds, the latter is 100 per cent. So, no one has died in this age group among those who have received both vaccines. The study period always begins 7 days after the second vaccination.
The research looked at how effective the different types of vaccines are for specific age groups. Overall, Sinopharm has the lowest efficacy. It protects against the infection in only 43.1 per cent among those over the age of 85.
Data collection for the study ended on June 10th.
This is important because the latest outbreak of the epidemic is no longer included in the study. It is also important to note that the effectiveness of vaccines decreases significantly after half a year, writes telex.hu.
Tamás Ferenci, a biostatistician at the University of Óbuda, also gave his opinion on the results of the study. Ferenci emphasised that the study is not about the current performance of the vaccines. “We need one thing. We need to know the results earlier, especially in an epidemic like this where a week matters. But it is very simple: we have the data, and we have the analysis program required for preparing a study like the one presenting the current results,” said Ferenci.
