Don’t dismiss their concerns. It’s normal to have questions about a new vaccine, and the amount of misconceptions about the vaccines can be overwhelming. Listen without judgment and try to get to the root of why they may have doubts about the vaccines.
Addressing misinformation about COVID-19 vaccines is an important part of encouraging others to get their vaccine. For example, some people who are hesitant about the vaccine fear the vaccines’ potential side effects. Talk about how the vaccines are designed to cause an immune-system response which is the cause of these temporary effects.
By choosing to get a COVID vaccine, they are protecting themselves as well as others in their community. Let them know that they have the power to fight back against this disease and do something about ending the pandemic.
Try your best to connect with them and discuss COVID-19 in general rather than just the vaccines. Most likely, they also feel frustrated that COVID has restricted their lives over the past year and want to go back to normal life. Let them know that by getting their vaccine, they are helping life get back to what it was pre-pandemic.
If they have a question or concern that you cannot answer, offer to help them look for information from a trusted source like the CDC or the WHO. You may consult the CDC's vaccine page or the WHO's page for COVID vaccine safety.
