As Rowan County continues to develop our vaccine distribution plan, we would like to continue to share information regarding the development of safe and effective vaccines.
It is always better to prevent a disease than to treat it after it occurs.
Vaccines and Immunizations | CDC
The COVID-19 vaccine is a set of two shots provided to a person to give them protection from the coronavirus. COVID-19 vaccination helps protect you by creating an antibody response without having to experience sickness. Sometimes after vaccination, the process of building immunity can cause symptoms, such as soreness where you received the injection or fatigue. These symptoms are normal and are a sign that the body is building immunity.
Understanding How COVID-19 Vaccines Work | CDC
How do mRNA vaccines (Pfizer and Moderna) work?
COVID-19 Vaccine Communications Toolkit | CDC
For now, yes. The three leading vaccines are Pfizer, Moderna, and AstraZeneca. All require a second dose 21-28 days after the first shot.

Multiple vaccines to protect people from COVID-19 are in specific phases of development or approval. The chart below summarizes key facts for three companies that are developing the vaccines: Pfizer, Moderna and AstraZeneca.

Some people may have temporary reactions after being vaccinated, such as some pain and swelling at the injection site, tiredness or feeling off for a day or two. These mRNA vaccines are expected to produce side effects after vaccination, especially after the 2nd dose.
Side effects may include:
No significant safety concerns were identified in the clinical trials. At least 8 weeks of safety data were gathered in the trials. It is unusual for side effects to appear more than 8 weeks after vaccination.
