Is the vaccine safe?

Yes. Vaccines are the safest medicines used in the United States. 

COVID-19 vaccines were tested in large clinical trials to make sure they meet safety standards. Many people were recruited to participate in these trials to see how the vaccines offers protection to people of different ages, races, and ethnicities, as well as those with different medical conditions. 

  • The Food and Drug Administration (FDA) carefully reviews all safety data from clinical trials and authorizes emergency vaccine use only when the expected benefits outweigh potential risks.
  • The Advisory Committee on Immunization Practices (ACIP) reviews all safety data before recommending any COVID-19 vaccine for use. Learn how ACIP makes vaccine recommendations.
  • FDA and CDC will continue to monitor the safety of COVID-19 vaccines, to make sure even very rare side effects are identified.

The following recommendations apply to non-healthcare settings. For related information for healthcare settings, visit Updated Healthcare Infection Prevention and Control Recommendations in Response to COVID-19 Vaccination.

Fully vaccinated people can:

  1. Participate in many of the activities that they did before the pandemic; for some of these activities, they may choose to wear a mask.
  2. Resume domestic travel and refrain from testing before or after travel and from self-quarantine after travel.
  3. Refrain from testing before leaving the United States for international travel (unless required by the destination) and refrain from self-quarantine after arriving back in the United States.
  4. Refrain from routine screening testing if feasible.

Infections happen in only a small proportion of people who are fully vaccinated, even with the Delta variant. However, preliminary evidence suggests that fully vaccinated people who do become infected with the Delta variant can spread the virus to others. To reduce their risk of becoming infected with the Delta variant and potentially spreading it to others: CDC recommends that fully vaccinated people:

Wear a mask in public indoor settings if they are in an area of substantial or high transmission. (To find out the current level of transmission in Riley County please visit the CDC COVID Data Tracker )

  1. Fully vaccinated people might choose to mask regardless of the level of transmission, particularly if they or someone in their household is immunocompromised or at increased risk for severe disease, or if someone in their household is unvaccinated. People who are at increased risk for severe disease include older adults and those who have certain medical conditions, such as diabetes, overweight or obesity, and heart conditions.

Get tested if experiencing COVID-19 symptoms.

If you came into close contact with someone with COVID-19 get tested 3-5 days after the date of your exposure and wear a mask in public indoor settings for 14 days after exposure or until a negative test result.

Isolate if they have tested positive for COVID-19 in the prior 10 days or are experiencing COVID-19 symptoms.

Follow any applicable federal, state, local, tribal, or territorial laws, rules, and regulations.
