An investigation by the United States has revealed that immunity has been reduced of Pfizer, Modana, Johnson & Johnson vaccines for corona virus

More than 800,000 people who received the vaccine have contributed to the research. The study found that the safety of these three vaccines, which are widely used in the United States, has dropped significantly over the past six months.

The Pfizer vaccine is down 58%, the Modana vaccine is down 43% and the Johnson & Johnson vaccine is down 13%.

With these test results, the Northern Hemisphere is in turmoil due to predictions that the number of infections and deaths will increase in the coming winter.
