Wide uptake of the vaccine was essential to bringing the University of Maryland community back to campus. COVID-19 vaccines are safe, effective, and free. Get answers to frequently asked questions and bust myths about vaccines.

Vaccine Boosters: The CDC recommends a booster vaccine for individuals as soon as they are eligible.

It is important to stay up to date on your COVID-19 vaccines.

COVID-19 Vaccine Facts

The vaccines are safe

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 offer protection to people of different ages, races, and ethnicities, as well as those with different medical conditions. Though the accelerated timeline for vaccine development was unprecedented, safety remains a top priority.

 

The vaccines are effective

There are currently three available vaccine types in the US.  All three are considered quite effective.  Additional COVID-19 vaccines remain in clinical trial phases.

  • Moderna
  • Pfizer
  • Johnson & Johnson
  • Novavax

Exact levels of efficacy may vary as new COVID-19 variants emerge, and this continues to be studied.  For up to date information from the CDC regarding effectiveness of the above vaccines, visit the CDC website.

Very few serious problems are reported after COVID-19 vaccination

Most people do not have serious problems after receiving a vaccine. Some people might experience temporary injection site soreness, fever, chills, fatigue, headache, and  muscle pain after receiving the COVID-19 vaccines. 

All of these side effects should go away in 24 to 48 hours. If you experience any symptoms after vaccination, you may choose to take an over-the-counter fever reducer or pain reliever. 

Most side effects are normal signs that your body is building protection. Historical information and on-going research shows us that long-term side effects are typically not a concern with vaccines. Severe and serious side effects of vaccines are rare and when they do occur, it is usually within 6 weeks of receiving a vaccine. Research related to the COVID-19 vaccines will continue, and the FDA and CDC are continuing to monitor safety to ensure long-term side effects are identified, should they arise. If an issue is identified, experts will take immediate action to determine the best course of action. 

COVID-19 vaccination is appropriate for those who previously tested positive for COVID-19

If you previously tested positive for COVID-19, you may still receive the vaccine, provided you have completed your period of isolation and are asymptomatic. 

Reinfection with the COVID-19 virus is possible and experts do not yet know how long someone is protected from getting sick again after recovering from COVID-19. If you are able, receiving the vaccine is the best way to protect yourself. 

Vaccine Protection for New Virus Mutations

The Centers for Disease Control and Prevention (CDC), in collaboration with other public health agencies, continue to monitor emerging SARS-CoV-2 variants closely.  

While there is evidence from laboratory studies that show current vaccines may be less effective against some of the newly identified strains, the immune response is incredibly complex, so the vaccine is still expected to provide some degree of protection.  

These variants, including Omicron and its sub-variants, seem to spread more easily and quickly than other variants, which may lead to more cases of COVID-19. An increase in the number of cases will put more strain on healthcare resources, lead to more hospitalizations, and potentially more deaths.

At this time much remains unknown.  However, it is normal and expected for mutations to occur in many types of viruses.  For instance, we deal with mutations in the flu every year. Experts will continue to monitor SARS-CoV-2 variants and if necessary, the vaccine development process can accommodate changes, though we are not at that point right now. 

As a reminder, even after receiving the vaccine, everyone should continue engage in good hand hygiene, and stay home when not feeling well.

COVID-19 vaccinations are required for all students, faculty, and staff coming to campus this fall semester

Information about COVID-19 Boosters

Boosters are an important part of protecting yourself from getting seriously ill or dying from COVID-19. They are recommended for most people.

Vaccines are readily available across the US.  However, COVID-19 prevention strategies continue to remain an important part of slowing the spread of the virus.  Continue washing and sanitizing your hands, stay home if you are not feeling well, and wear a face-covering if you are not fully vaccinated and boosted.
