Dartmouth-Hitchcock Health recommends the COVID-19 vaccine, and we hope you will choose the vaccine when it is available for you. We understand that deciding whether to get a new vaccines can create many questions and concerns. To put your mind at ease, our medical experts have weighed in to dispel some myths and share facts, about the vaccine.
True or false?

The COVID-19 vaccine will give you the coronavirus.
None of the COVID-19 vaccines contain the live coronavirus so it is impossible to get coronavirus from the vaccine. There is still a small chance that you could get COVID-19 after your vaccine. If you do, it would be from the environment and not the vaccine itself.
Once I get the COVID-19 vaccine I can stop wearing a mask and physical distancing from others.
You will still need to wear a mask, wash your hands, and practice physical distancing even after you get the COVID-19 vaccine. These preventative measures will stay in place until more people are vaccinated and health experts have a better idea of how long the vaccine’s immunity lasts. Even though the vaccines are 95% effective, they are not 100%, which is why people still must use caution even after they are vaccinated.
There is no point in getting the COVID-19 vaccine because we don’t know how long the vaccine provides immunity.
You may need to get a booster for the COVID-19 vaccine as different strains of the virus appear. That doesn’t mean that you shouldn’t get the vaccine as soon as it is available to you. As more time passes, and more people get vaccinated, health experts will begin to have a better idea of how long the immunity will last. Some recent studies have suggested that it should last for at least 6 months.
I have already had COVID-19 so that means I don’t need to get vaccinated.
Even if you have had COVID-19 you will still benefit from getting vaccinated, especially since there is evidence that people who have had COVID-19 can get it again. Early evidence suggests that natural immunity from COVID-19 can last anywhere from 4-8 months, but more research is needed in order to have a more accurate timeframe. In addition, some scientists feel that the vaccine offers better protection from COVID-19 than natural infection.
The COVID-19 vaccine can change your DNA.
Two COVID-19 vaccines currently available (Moderna and Pfizer-BioNTech) use something called messenger RNA (mRNA). This type of vaccine works with your body’s immune system and “teaches” it how to fight COVID-19. mRNA does enter your cells, but not in the part of the cell where DNA lives.
The messenger RNA (mRNA) technology used in the COVID-19 vaccine is brand new.
Using mRNA in vaccines has actually been in development for almost two decades. It was created for this very reason, to be able to respond quickly to new viruses and illness, such as COVID-19.
The COVID-19 vaccine has severe side effects
Most individuals who receive the vaccine will experience mild and short-term side effects such as sore arm, headache, chills, fatigue or muscle pain or fever. It is important to know that these side effects mean that the vaccine is working with your immune system as it should. And although extremely rare, some people can have severe allergic reactions to ingredients used in a vaccine. That’s why experts recommend people with a history of severe allergic reactions — such as anaphylaxis (which is a severe, potentially life-threatening allergic reaction) — to the ingredients of the vaccine should not get the vaccination. Anyone who gets a COVID-19 vaccine is observed for a 15-minute period to ensure that there are no serious side effects. Those who have a history of vaccine reactions will be observed for 30 minutes.
