COVID-19 vaccinations and boosters

COVID-19 Vaccines

Whether you’ve had COVID-19 or not, getting vaccinated is the most effective way to stop the spread and boost your immunity.

COVID-19 boosters

Because COVID-19 vaccines become less effective after a period of time, boosters are the best way to keep your immunity strong. If you’re six months or older, the Centers for Disease Control and Prevention (CDC) recommend getting a booster after completing your primary COVID-19 vaccination series.

Call your provider’s offices to learn if you are eligible for the latest COVID-19 vaccination and where you can get the vaccine.

COVID-19 testing

Depending on your needs and time frame, there are different tests to choose from. We’ll help you figure out which test is the best choice for you.

If you want to know if you currently have COVID-19:

If you’re feeling sick, it can be best to stay home and avoid contact with others until you know more. To find out if you are infected, our symptom checker can help you figure out if a virtual visit or in-office visit is the next best step. Start the symptom checker ›
If necessary, diagnostic tests can show if you are currently infected with SARS-CoV-2, the virus that causes COVID-19. There are two types of COVID-19 diagnostic tests:

  1. Molecular tests (such as polymerase chain reaction (PCR) tests): Highly-accurate tests that detect the genetic material or nucleic acid present inside a virus particle. These tests take about three to seven days to get results.
  2. Antigen tests (aka rapid tests): Same-day tests that detect one or more specific proteins from a virus particle. These tests are less sensitive and slightly less accurate.
If you want to know if you have been exposed to COVID-19 in the past:

Antibody tests look for antibodies in your blood that your immune system produced in response to SARS-CoV-2, the virus that causes COVID-19. Antibody tests should not be used to diagnose a current infection and, at this time, should also not be used to check for immunity. Samples for antibody tests are typically collected by a doctor or other medical professional by taking blood from a finger stick or your vein.
