WHAT EXACTLY IS AN mRNA VACCINE?
Messenger RNA (mRNA) is not new technology; it’s been studied for decades. mRNA gives our cells the directions to make a piece of the spike protein that is unique to the SARS-CoV-2 virus that causes COVID-19. After the cells have the directions, the mRNA degrades; the mRNA does not enter the nucleus of the cell or affect our DNA/genetic material. Because only part of the viral protein is made, it does not do any harm to the person. The protein causes the immune system to produce antibodies to fight what it thinks is an infection. It’s like the directions on a cake mix box: you buy the cake mix, follow the directions on the box, make the cake and throw away the box.
IS IT SAFE TO GET?
Safety was the number one priority in the development and approval process. Both the Pfizer and Moderna vaccines have been rigorously tested and went through all the same safety procedures and steps as other vaccines. Multiple safety systems will continue to monitor their safety for the foreseeable future. Because the vaccine does not contain the virus, or parts of it, it cannot cause COVID-19. The vaccines do not contain preservatives, eggs, latex (even the stopper) or gelatin.
WHO SHOULD GET IT?
Pfizer is authorized for everyone over 16 years of age, Moderna for everyone over 18. Anyone considered at high risk for severe disease due to age or underlying health conditions are especially encouraged to be vaccinated.
- What if you already had COVID? Because it’s not known how long immunity lasts after the illness, vaccination is recommended, but you may consider postponing for 90 days after your infection. However, a mild case may not have given a person much immunity.
- What if you have allergies? People who have common allergies to foods, pets, venom, environmental allergens, oral medications, latex, eggs, or gelatin can receive the vaccine.
- What about pregnant or breastfeeding women? They may choose to be vaccinated depending on their risk of community transmission risk, but they should talk to their healthcare provider.
WHO SHOULD NOT GET IT?
Anyone who had a severe immediate allergic reaction (anaphylaxis) after their first dose should not receive a second dose, even of another brand. Anyone who has had a severe allergic reaction to any component of the vaccines should not receive the vaccine. Severe allergic reactions are very rare and all occurred within the observation time and were treated successfully.
WHAT ARE THE SIDE EFFECTS?
Local reactions at the injection site: redness, pain, swelling, stiff arm similar to after other vaccines or shots. Fever, chills, fatigue, headache, swollen glands in the shot arm, vomiting, diarrhea, body aches, muscle aches can also occur. These are signs the immune system is responding to the vaccine appropriately. Most side effects resolve within 1-3 days.
