The number of coronaviruses in the country has increased and the number of patients has reached four crore. In the last 24 hours, 13,086 new corona patients have been diagnosed. So far 24 people have died.
The corona has so far claimed the lives of 5,25,233 people across the country. Efforts are being made to prevent corona infection. In many states, the situation is once again critical.
Accelerated vaccination campaigns are underway across the country and so far millions of people have been vaccinated against corona. New revelations about the corona virus and the corona vaccine are being made every day around the world.
Research by the All India Institute of Medical Sciences (AIIMS), New Delhi, has found that even after six months, the anti-corona vaccine does not have much effect on the human body. Its effect is diminished.
According to AIIMS doctors, one study found that after taking both doses of Korana, the vaccine helps protect against omecron for about two weeks to two months. Its effect lasts up to 52.2 per cent during this period.
AIIMS conducted the research on its own health workers. Health workers were selected for this research because they have a higher risk of infection, so that the results of the research will be more effective.
In the research, research was conducted on 11,474 health workers at the hospital during omicron infection in AIIMS. This included medical students, resident doctors, senior professor doctors, nursing staff, paramedical staff and other workers.
The aim was to note the effect of this vaccine on recurrent omepron infection. Eighty-three percent of the health workers involved took both doses of the vaccine. Of these, 88 per cent had received the covacin vaccine and 11 per cent had received the covshield vaccine.
At the time of the omicron infection, 2527 AIIMS health workers were infected. Between the first and second wave of corona, about 28.40 percent (1007) of health workers were re-infected with omecron.
Health workers surviving a corona infection. Of these, 1,520 health workers, or 19.17 per cent, have fallen victim to omacron infection. Of these, 98.4 per cent were found to be mild infections and 1.6 per cent were found to be moderately infected in health workers.
The study found that health workers who took both doses of the vaccine for 14 to 60 days were less likely to be infected with omacron. The effect of the vaccine to protect against corona has been 52.5 percent effective on them.
On the other hand, those who were vaccinated for 61 to 120 days had a vaccination effect of 35.2 per cent, while those who were vaccinated for 121 to 180 days had a corona vaccine effect of 29.4 per cent.
Studies have shown that the effect of vaccines decreases over time. As a result, after six months, the vaccine is less effective on omecron. Six months later, the vaccine showed no significant effect.
Health workers who had been vaccinated for more than six months were found to be more infected with omecron. The international medical journal Lancet Regional Health South-East Asia has also taken the AIIMS study seriously and published it in its journal.
Participating in the study, Associate Professor of Medicine, Dr. Arvind Kumar says the study shows that if three to four months have elapsed since the vaccination, those working in hazardous conditions should be vaccinated by health workers.
Studies have also shown that alpha, delta, gamma or any other type of omecron improves the body's immunity after infection. A Hindi website has reported about this.
