Second dose of Vaccine

Second-Dose COVID-19 Vaccine Proven Vital
Scientists from Stanford University started a comprehensive study to see the effect of Pfizer and BioNTech vaccines on the immune system. In the article published as a result of the study, it was revealed that the second dose of COVID-19 vaccine management triggered important immune cells in the human body.
Scientists from Stanford University started a study to investigate how Pfizer and BioNTech vaccines have effects on human immunity. For the article published on July 12, researchers who examined the COVID-19 vaccine produced by Pfizer revealed how important it is to get a second dose of the vaccine.
The antibodies of vaccinated volunteers were examined, their immune signal levels were measured, and the types of 242,479 individual immune cells were characterized. As a result of all these examinations, it was determined that a group of cells that are normally dormant and provide immunity were activated by the second dose.

B and T cells increased significantly with the second dose
As you know, the decisions taken for the number of doses of COVID-19 vaccines are constantly changing. While two doses seem sufficient for drugs with mRNA infrastructure such as Pfizer and Moderna vaccines, a third dose is considered necessary for inactivated vaccines such as Sinovac.

Scientists from Stanford University have started a new study for the Pfizer vaccine, where two doses seem enough. As part of this study, the immune system of people vaccinated at Stanford since December 2020 was examined, and the effects of the first and second doses of the vaccine on immunity were examined.
In the article, which was written as a result of long-term research, it was stated that the second dose of COVID-19 vaccine provides support to a part of the immune system that provides extensive protection. Bali Pulendran, a professor of pathology, microbiology and immunology, one of the lead authors of the study, said that after the second dose, they saw a significant increase in B and T cells in the immune system and fighting against the virus.
Stating that the number of the monocyte group that provides protection against viral infections increased 100 times with the second dose, Pulendran used the following statements; “The remarkable increase in the number of these cells occurred just one day after the second dose. The cells can act not only against SARS-CoV-2, but also against other viruses.”
