Every hour, approximately 400 Kentuckians are being vaccinated at the UK COVID-19 Vaccine Clinic. We are proud to be the largest vaccination site in the Commonwealth, and as more individuals get vaccinated, we’re experiencing an increase in questions related to booster shots. Below, we address the most frequently asked questions about the second dose of the COVID-19 vaccine.

Why is a booster shot necessary? 

The CDC explains that the first dose of the COVID-19 vaccine “primes the immune system to recognize the virus” and that the second dose “strengthens the immune response.”

If I’ve received the first dose of the Pfizer vaccine, when should I get my booster shot? 

According to the CDC, you should receive your booster shot at least 21 days after receiving your first dose of the Pfizer-BioNTech COVID-19 vaccine. You should get your second shot as close to the 3-week interval as possible. However, you can receive the second dose up to 6 weeks after the first dose, if necessary.

If I’ve received the first dose of the Moderna vaccine, when should I get my booster shot? 

According to the CDC, you should receive your booster shot at least 28 days after receiving your first dose of the Moderna COVID-19 vaccine. You should get your second shot as close to the 4-week interval as possible. However, you can receive the second dose up to 6 weeks after the first dose, if necessary.  

Can I receive my booster shot at UK’s Kroger Field Vaccine Clinic if I received my first dose from another provider? 

At this time, the only way to receive your second dose at UK’s Kroger Field Vaccine Clinic is if the individual also received their first dose at the clinic. We are not accepting appointments for individuals who received their first shot at a different location. 

What are the common side effects of receiving the booster shot? 

The CDC has identified a few common side effects you might experience after receiving the COVID-19 vaccine. It is likely you may have slight pain and swelling at the injection site. You also may experience chills, fever, fatigue or headaches as a result of receiving the vaccine. If symptoms persist longer than 24 hours, we recommend reaching out to your health care provider.
