The Covid-19 vaccine developed by Pfizer and BioNTech produces a stronger immune response than the other 3 vaccines.
This was revealed in a medical study conducted in the United States.
The Stanford University study compared Pfizer, AstraZeneca, Sputnik V and cyanoform vaccines.
The study found that the rates of antibodies protecting the intestinal tract from the corona virus vary across the four vaccines.
According to research, the number of antibodies produced by cyanobacteria and Sputnik V vaccines is lower, the rate is milder in AstraZeneca and higher than in Pfizer vaccine.
Much research has been done for some time on the causes of different immune responses to different types of vaccines.
There are several reasons for this, such as the active ingredients in each diet and the interval between the first and second doses.
The study, conducted in July, included 196 people from Mongolia who had completed the vaccine.
All four vaccines were used in these individuals, and at that time, 89.2% of adults in Mongolia were vaccinated with the cyanobacterial vaccine.
Similarly, some people were given Sputnik V or AstraZeneca vaccines.
According to researchers, people who use these three vaccines are more likely to develop a breakthrough infection (a term used for the disease after vaccination) than those who use the Pfizer vaccine.
The researchers said that additional medical measures, such as booster doses, should be used for better vaccines to control the Covid-19 epidemic worldwide.
The study did not provide vaccine dosages or other details.
The researchers said that the corona virus outbreak in Mongolia in the summer of 2021 was the result of an alpha type and that antibody levels were found to be higher in all vaccine groups after the breakthrough infection.
He said that in view of the increasing number of cases of Corona virus and limited availability of more effective vaccines, currently low-dose vaccines could help reduce the incidence of disease, hospitalization and mortality.
