Description An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA to produce an immune response. Wikipedia

If you’re eligible for the vaccine, you should get it. The vaccine protects you and others from COVID-19. Talk to your healthcare provider about getting the vaccine.

An mRNA vaccine might not be as effective in people who have a weakened immune system, cancer or a history of cancer. If you have cancer or another health condition, talk to your provider about getting before getting any kind of vaccine, including the mRNA vaccines for COVID-19.

People who are allergic to any of the ingredients in the mRNA vaccines should not get them. It’s rare, but some people have a serious allergic reaction after getting the vaccine.

The mRNA vaccines in current use are very effective at protecting people from getting and spreading COVID-19. Some studies show that these vaccines are at least 90% effective in people who are fully vaccinated (have had both doses of the vaccine).

Vaccines offer people protection from disease. People who've already been infected with the virus that causes COVID-19 infection develop the same type of immunity. But the COVID-19 mRNA vaccine protects people from the virus without having to get sick from the infection. The vaccine drastically reduces your risk of severe illness and the long-term effects of COVID-19 (long COVID or long-hauler COVID-19).

COVID-19 mRNA vaccines are very safe. Millions of people have received the vaccine with few side effects.

Though uncommon, allergic reactions to mRNA vaccines have occurred. Reactions usually happen within one hour after getting a shot. So, your provider will ask you to stay in the area for about 15 minutes after your dose to check for any problems. Signs of an allergic reaction to the mRNA vaccine include:

In rare cases, some people experience myocarditis (inflammation in the heart muscle) or pericarditis (inflammation in the heart’s lining) after getting a COVID-19 mRNA shot. This affects young people and adolescents more than adults. Signs of myocarditis and pericarditis include:
