Ensuring COVID-19 Vaccines Work

• All COVID-19 vaccines currently available in the United States are effective at preventing COVID-19 as seen in clinical trial settings.
• Research provides growing evidence that mRNA COVID-19 vaccines offer similar protection in real world conditions.
• COVID-19 vaccination is an important tool to help stop the COVID-19 pandemic.
• COVID-19 vaccination helps protect people from getting sick or severely ill with COVID-19 and might also help protect people around them.
• To receive the most protection, people should receive all recommended doses of a COVID-19 vaccine.
• Some people who are fully vaccinated against COVID-19 will still get sick because no vaccine is 100% effective. Experts continue to monitor and evaluate how often this occurs, how severe their illness is, and how likely a vaccinated person is to spread COVID-19 to others.
• CDC recommends you get a COVID-19 vaccine as soon as one is available to you.
