On the other hand, we focused on the effects of the SARS-CoV-2 on innate immunity, including enhancing viral adhesion, increasing the rate of virus invasion, inhibiting the transcription and translation of immune-related mRNA, increasing cellular mRNA degradation, and inhibiting protein transmembrane transport. Here, on the one hand, we devoted ourselves to summarizing the combined action of innate immune cells, cytokines, and chemokines to fine-tune the outcome of SARS-CoV-2 infection and the related immunopathogenesis. This review summarizes the molecular mechanism by which SARS-CoV-2 escapes the host immune system, including suppressing innate immune production and blocking adaptive immune priming. As innate immunity is the body’s first defense against viruses, understanding the inhibitory effect of SARS-CoV-2 on innate immunity is of great significance for determining the target of antiviral intervention. Virus pathogenicity is closely related to the immune status of the host.

However, the pandemic is still developing, and new mutations are still emerging. Since the virus epidemic, many pathogenic mechanisms have been revealed, and virus-related vaccines have been successfully developed and applied in clinical practice. The newly identified Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has resulted in a global health emergency (COVID-19) because of its rapid spread and high mortality. Learn more about the process for FDA approval. These vaccines were found to meet the high standards for safety, effectiveness, and manufacturing quality FDA requires of an approved product. inspections of the sites where the vaccine is made.vaccine testing results to ensure vaccine quality, and.as well as details of the manufacturing process,.

preclinical and clinical trial data and information,.

Before granting approval, FDA reviewed evidence that built on the data and information submitted to support the EUA.

Learn more in this video about EUAs.įDA has granted full approval for some COVID-19 vaccines. The EUAs allowed the vaccines to be quickly distributed for use while maintaining the same high safety standards required for all vaccines. Initially, they determined that COVID-19 vaccines met FDA’s safety and effectiveness standards and granted those vaccines Emergency Use Authorizations (EUAs). Any side effects from getting the vaccine are normal signs the body is building protection.īefore vaccines are made available to people in real-world settings, FDA assesses the findings from clinical trials.

People get this protection from a vaccine, without ever having to risk the potentially serious consequences of getting sick with COVID-19.

At the end of the immune building process, our bodies have learned how to help protect against future infection with the virus that causes COVID-19.

This response is similar to what your body does if you get sick with COVID-19, but is temporary. This triggers our immune system to produce antibodies and activate other immune cells to fight off what it is an infection. Our immune system recognizes that the spike protein does not belong there.

Next, our cells display the spike protein on their surface.

After the spike protein piece is made, our cells break down the vector virus and remove it. The spike protein is found on the surface of the virus that causes COVID-19. It enters the muscle cells and uses the cells’ machinery to produce a harmless piece of what is called a spike protein. The vector virus in the vaccine is not the virus that causes COVID-19, but a different, harmless virus.

Viral vector COVID-19 vaccines are given in a muscle in the upper arm.

Any side effects from getting the vaccine are normal signs the body is building protection. The benefit is that people get this protection from a vaccine, without ever having to risk the potentially serious consequences of getting sick with COVID-19.

At the end of the process, our bodies have learned how to help protect against future infection with the virus that causes COVID-19.

This is what your body might do if you got sick with COVID-19. This triggers our immune system to produce antibodies and activate other immune cells to fight off what it thinks is an infection. Our immune system recognizes that the protein does not belong there.

Next, our cells display the spike protein piece on their surface.

After the protein piece is made, our cells break down the mRNA and remove it, leaving the body as waste.

Once inside, they use the cells’ machinery to produce a harmless piece of what is called the spike protein.

After vaccination, the mRNA will enter the muscle cells.

First, mRNA COVID-19 vaccines are given in the upper arm muscle or upper thigh, depending on the age of who is getting vaccinated.
