Part 1 – Positive Impacts of COVID – mRNA Vaccine

We thought of sharing some positive impacts of COVID. We thought this is the right time to start series of these blogs – world is facing lot of sufferings and losses. We are seeing a lot of hopes in the vaccines. Lets share positivity around us and take care of mental and physical health. 

What is a Vaccine

First vaccine was created and used by Edward Jenner, he used materials from cowpox pustules to provide protection against smallpox.  Vaccines prevent many millions of illnesses and save numerous lives every year. As a result of widespread vaccine use, the smallpox virus has been completely eradicated and the incidence of polio, measles and other childhood diseases has been drastically reduced around the world. 

How mRNA Vaccine is different

Conventional vaccine approaches, provide durable protection against a variety of dangerous diseases. But due to the pandemic, researchers across whole world were trying create new vaccines. One such method is mRNA Vaccine.

Messenger RNAs, also known as mRNA, are one of the types of RNA that are found in the cell. This particular one, like most RNAs, are made in the nucleus and then exported to the cytoplasm where the translation machinery, the machinery that actually makes proteins, binds to these mRNA molecules and reads the code on the mRNA to make a specific protein. So in general, one gene, the DNA for one gene, can be transcribed into an mRNA molecule that will end up making one specific protein.

Companies - Moderna and Pfizer have worked and waiting for approval on mRNA vaccines that allow people to build immunity to viruses like Covid-19. These vaccines contain specifically designed mRNA that instructs cells how to make viral proteins. The mRNA vaccine prompts cells to manufacture and release a COVID-shaped protein in sufficient quantities to provoke an immune response. That immune response prepares the body to quickly recognize and attack any COVID-shaped protein encountered in the body.

Lets hope these Vaccines get approved and save humans. If COVID vaccine works well, researchers can use this mRNA vaccine for Cancer treatment as well.
