With Pfizer
/ Biotech's Code 19 vaccine, the rate of protection against the disease begins
to decrease 2 months after vaccination is completed, however, there is strong
protection against disease severity, hospitalization, and death.
This has
appeared in 2 different medical research reports in the real world.
Research in
Israel and Qatar reinforces the idea that people should take precautions to
prevent the disease even after a full vaccination.
A study was
conducted in Israel involving 4,800 medical workers.
The results
showed that 2 months after the second dose of the vaccine, especially in men,
antibody levels began to drop sharply in people over the age of 65 and in
people with weakened immune systems. Is more prominent.
The study Pfizer vac incused on the level of antibodies that neutralize the virus, and experts said
that the level of antibodies decreases by 5 to 10 percent each year after
vaccination against measles or other diseases.
"We
discovered that there was a significant reduction in antibody levels after both
doses of the Pfizer vaccine," he said.
The study
also indicated that vaccines could be extended to immunizations after defeating
Code 19.
Another
study in Qatar looked at patients who contracted COD-19 after vaccination.
The Pfizer
vaccine was used to vaccinate most people in Qatar.
The
researchers said that the protection against the disease with the Pfizer vaccine is
at its peak in the first month after the second dose and gradually decreases in
the coming months.
He said that
four months after the completion of vaccination, the rate of immunity decreases
rapidly.
But he said
the hospitalization and mortality rate was over 90 percent.
According to
research, behaviors can also play a role in reducing the effectiveness of
vaccines, as vaccinators are more likely to communicate and are more likely not
to take precautions.
Research
shows that such behavior reduces the effectiveness of vaccines in the real
world, which may explain the potential for less effectiveness.
The
researchers said that this indicates that countries need to be prepared for a
new wave of Code 19, as the results suggest that vaccine protection against the
disease will decrease in the coming months. Increases the likelihood of a new
wave of disease.
The results
of both research reports were published in the medical journal New England
Journal of Medicine.
The results
of these research reports came to light when a study conducted in the United
States on October 5, 2021, revealed that six months after the use of the second
dose, the effectiveness of the Pfizer vaccine has halved.
Pfizer and
Caesar of the American Medical Research Institute reviewed data from 3.4
million people who had been vaccinated, showing that the vaccine provides
overall serious protection but significantly increases its effectiveness
against common diseases. Reduces Is
The results
of this study, published in a medical journal, show that Pfizer's efficacy
begins to decline within a month of the second dose, and its efficacy halves after
6 months.
