When will we get Covid vaccines?
Now that both Pfizer’s and Moderna’s COVID-19 vaccines have been approved, when will a vaccine be available for everyone? Production of these vaccines is limited, and distribution will be difficult. Meaning the government has to decide who will get the vaccine (first, second, third, and so on.) Both Pfizer and Moderna’s vaccines are created using the same technology; they inject a genetic molecule called mRNA, which causes a person’s cells to create a viral protein that triggers a desired immune response. The mRNA molecule is simply a messenger that tells the body how to create an immune response. Because of the mRNA component, which breaks down very easily, the vaccine must be kept cold. The Pfizer vaccine is stored in a freezer at “ultra cold” temperatures, while the Moderna vaccine can be stored in a regular refrigerator, which makes transportation of the vaccine difficult.
The vaccines are given to people who are at the most risk, such as healthcare workers, nursing homes, and other long-term facilities. After it's given to health care workers, it will be given to the elderly and those with medical conditions. Once all of these steps have been completed they will begin giving it to the general population, less so for kids, since kids aren't typically at high risk of severe illness. Since we are working on getting the vaccine out to the public now, it's expected that everyone will have the vaccine by late 2021.
