Tier 1 COVID vaccination...

Reminder getting a #COVID19 vaccine does NOT give someone instant immunity. It takes 10-14 days for immunity to develop. By 28 days immunity level is at ~50% when 2nd shot is to be received. It takes another 20-30 days to reach 95% immunity.

People make mRNA all the time. In our cells, DNA in the nucleus is used to make mRNA, which is sent to the cytoplasm where it serves as a blueprint to make proteins. Most of the time, the proteins that are produced are needed to help our bodies function. mRNA vaccines take advantage of this process by introducing the mRNA for an important protein from the virus that the vaccine is trying to protect against. In the case of COVID-19, the important protein is the spike protein, ...so the COVID-19 spike protein mRNA is introduced into the cytoplasm of muscle cells and nearby dendritic cells, where it causes the cells to produce only this one COVID-19 protein. Our immune systems recognize the spike protein and make antibodies to it. These antibodies protect us, so that if we are exposed to SARS-CoV-2 in the future, our immune system is ready and we don’t get sick ( or we don’t get as sick). The two vaccines include: mRNA This mRNA is for the spike protein of SARS- CoV-2, the virus that causes COVID-19. Lipids - These are molecules that are not able to dissolve in water. They protect the mRNA, so that it does not break down before it gets into our cells. These can be thought of as little bubbles of fat, which surround the mRNA like a protective wall. There are four different lipids in the Pfizer vaccine; one of which is cholesterol. The lipids are the most likely components of the vaccine to cause allergic reactions. Salts - The vaccine contains four salts. One is table salt. The salts are used to keep the pH of the vaccine similar to that found in the body, so that the vaccine does not damage cells when it is administered. Sugar This ingredient is literally the same as that which you put in your coffee or on your cereal. In the vaccine, it helps keep the bubbles of fat from sticking to each other or to the sides of the vaccine vial. These are the only ingredients in the mRNA vaccine. It does not include any of the following: fetal material, DNA, antibiotics, blood products, or microchips.

A FAQ is "what jobs are most likely to catch a coronavirus". Here are a few charts.
