What are COVID-19 Vaccines?
COVID-19 vaccines are vaccines that have been developed to help protect individuals from contracting COVID-19, a highly contagious respiratory illness caused by the SARS-CoV-2 virus. There are currently several COVID-19 vaccines available, including Pfizer-BioNTech, Moderna, and Johnson & Johnson. These vaccines have undergone extensive clinical trials, and have been shown to be effective in preventing COVID-19 infections, hospitalizations, and deaths.
The Pfizer-BioNTech and Moderna vaccines are mRNA vaccines, which means they contain a piece of genetic material from the SARS-CoV-2 virus that instructs cells to make a harmless protein that is unique to the virus. This protein triggers an immune response, which helps the body recognize and fight the virus if it is encountered in the future. The Johnson & Johnson vaccine, on the other hand, is a viral vector vaccine, which means it uses a harmless virus to deliver a piece of genetic material from the SARS-CoV-2 virus into cells to trigger an immune response.
It's important to note that COVID-19 vaccines are not 100% effective, and individuals who receive the vaccine may still contract COVID-19. However, receiving the vaccine can help reduce the severity of the illness and prevent hospitalization and death.
How do COVID-19 Vaccines Work?
COVID-19 vaccines work by training the body's immune system to recognize and fight the SARS-CoV-2 virus. When an individual receives a COVID-19 vaccine, the vaccine introduces a piece of the virus into the body, which triggers an immune response. The immune system then creates antibodies to fight the virus, which can help protect the individual from becoming infected with COVID-19.
The Pfizer-BioNTech and Moderna vaccines are mRNA vaccines, which means they contain a piece of genetic material from the SARS-CoV-2 virus that instructs cells to make a harmless protein that is unique to the virus.

The Johnson & Johnson vaccine, on the other hand, is a viral vector vaccine, which means it uses a harmless virus to deliver a piece of genetic material from the SARS-CoV-2 virus into cells to trigger an immune response.
It's important to note that COVID-19 vaccines do not contain live virus, and cannot give an individual COVID-19. Additionally, it takes time for the body to build immunity after receiving the vaccine, which means it's possible to contract COVID-19 in the days or weeks following vaccination.

Are COVID-19 Vaccines Safe?
COVID-19 vaccines have undergone extensive clinical trials to ensure their safety and effectiveness. Before a vaccine can be authorized for emergency use by the FDA, it must go through three phases of clinical trials to evaluate its safety and efficacy. The Pfizer-BioNTech, Moderna, and Johnson & Johnson vaccines have all undergone these clinical trials, and have been shown to be safe and effective.
While some individuals may experience side effects from the vaccine, such as fever, fatigue, or soreness at the injection site, these side effects are generally mild and temporary. Serious side effects from the vaccine are rare, and vaccine providers are trained to recognize and treat any adverse reactions that may occur.
It's important to note that individuals with certain medical conditions, such as severe allergies, may not be eligible to receive the COVID-19 vaccine. If you have questions about the safety of the vaccine for you, it's important to talk to your healthcare provider.
What are the Side Effects of COVID-19 Vaccines?
Like all vaccines, COVID-19 vaccines can cause side effects. The most common side effects of the COVID-19 vaccines include fever, fatigue, headache, chills, and soreness at the injection site. These side effects typically last for a few days, and can be managed with over-the-counter pain relievers.
In rare cases, individuals may experience more serious side effects from the vaccine, such as an allergic reaction. Vaccine providers are trained to recognize and treat any adverse reactions that may occur, and individuals are typically monitored for 15-30 minutes after receiving the vaccine.
It's important to note that the side effects of the vaccine are generally mild and temporary, and are a sign that the body is building immunity to the virus.
Do I Need to Wear a Mask After Vaccination?
While COVID-19 vaccines have been shown to be highly effective in preventing COVID-19 infections, it's still possible to contract the virus after vaccination. Additionally, it's not yet clear whether individuals who have been vaccinated can still transmit the virus to others.
As a result, the CDC recommends that individuals continue to wear masks and practice social distancing after vaccination, particularly in public settings where the risk of transmission is higher. Additionally, individuals should continue to follow local guidelines and restrictions related to COVID-19.
Who Should Get the COVID-19 Vaccine?
The COVID-19 vaccine is currently available to all individuals aged 12 and older in the United States. While the vaccine is not mandatory, the CDC recommends that all individuals who are eligible for the vaccine receive it.
Certain populations, such as healthcare workers, frontline essential workers, and older adults, may be prioritized for vaccination based on their risk of exposure or complications from COVID-19. However, all individuals who are eligible for the vaccine should receive it as soon as possible to help protect themselves and their communities from COVID-19.
Where Can I Get the COVID-19 Vaccine?
COVID-19 vaccines are currently available at a variety of locations, including pharmacies, healthcare providers, and community vaccination sites. Individuals can visit their state or local health department website to find information about vaccine availability and scheduling.
It's important to note that vaccine availability may vary by location, and individuals may need to be patient as they navigate the process of scheduling an appointment. Additionally, some vaccine providers may have specific eligibility requirements or restrictions, so it's important to check with the provider before scheduling an appointment.
