The Stanford University study compared Pfizer, AstraZeneca, Sputnik V, and cyanoform vaccines.
The study found that the rates of antibodies protecting human cells from the coronavirus virus vary across the four vaccines.
Research has shown that the number of antibodies to cyanobacteria and sputum V vaccines is lower, with the rate being milder in AstraZeneca and higher than in the Pfizer vaccine.
Much research has been done for some time on the causes of different immune responses to other 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, 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 experts, people who use these three vaccines are more likely to develop a breakthrough infection than Pfizer.
Experts say additional medical measures, such as booster doses, should improve vaccines to control the Covid 19 epidemic worldwide.
The study did not provide vaccine dosages or other details.
Experts said that the coronavirus wave in Mongolia in the summer of 2021 resulted from an alpha type and that antibody levels were higher in all vaccine groups after the breakthrough infection.
He said that because of the increasing coronavirus cases and limited availability of more effective vaccines, low-dose vaccines could currently help reduce the incidence of disease, hospitalization, and mortality.
