COVID-19 Vaccine Information

About the Vaccines

Now that the first COVID-19 vaccines are widely available, what’s next? We know getting at least 70% of the population vaccinated is crucial to containing the virus. To protect yourself and your loved ones, it’s important to get vaccinated.

What COVID-19 vaccines are currently available?

Several companies are developing vaccines. But three COVID-19 vaccines have received emergency use authorization from the U.S. Food and Drug Administration (FDA) so far. The first individuals to receive the vaccines will be frontline healthcare workers and residents of long-term care facilities.

How much will the vaccine cost?

If you’re a current CareFirst member, you’ll pay $0 for any FDA authorized vaccine when it’s made available to the public.

Were different races and ethnicities included in the vaccine trials?

How should I prepare myself and my body for the COVID-19 vaccine?

Preparing for your COVID-19 vaccination is pretty straightforward. Be sure to get a good night’s rest before your appointment and try to show up as hydrated as possible. Before you go, be sure to discuss any medical concerns with your doctor.

It’s currently recommended that you avoid taking over-the-counter pain medicine before you receive your vaccination, like ibuprofen, aspirin and acetaminophen, unless you take these regularly for other reasons. If needed, you may take over-the-counter pain relievers after your shot. It’s also recommended that you avoid taking antihistamines, like Loratadine and Cetirizine. These may help with seasonal or other allergies, but they won’t prevent any vaccine-related allergic reactions. Find out more about preparing for your COVID-19 vaccination from the CDC.

Can you still catch COVID-19 after being vaccinated?

All authorized COVID-19 vaccines are extremely effective, but no vaccine or medical treatment is 100% effective. That’s why a very small number of people, even after getting vaccinated, catch COVID-19. Plus, the vaccination process takes time. You aren’t fully protected until two weeks after your last vaccine dose, so you must remain vigilant in your protection against COVID-19 (wear a mask, wash your hands, practice social distance) while your body is ramping up its immune response.

Another reason you could test positive after vaccination is that COVID-19 has a 2–14-day incubation period. It’s possible that you were infected with COVID-19 before you got your vaccine, but you didn’t experience symptoms until a few days later. Remember, even if the vaccine doesn’t prevent you from catching COVID-19, it will lessen the severity of the infection and significantly reduces the chance of hospitalization.

After I’m fully vaccinated, can I stop wearing a mask and social distancing?

Yes! As of May 2021, the CDC has relaxed mask guidelines for fully vaccinated people. Fully vaccinated people no longer need to wear a mask or practice social distancing, except where required by federal, state, local, tribal or territorial laws, rules and regulations, including local business and workplace guidance. Remember, you’re only considered fully vaccinated two weeks after your final shot.

What should I do if I can’t or don’t want to get vaccinated?

If you can’t get vaccinated, or if you decide against it, it’s important to remain vigilant. To reduce the spread of the disease, and to avoid catching COVID-19, continue to follow existing safety guidance:

  • Wear a mask when you’re around other people who are not vaccinated
  • Practice social distancing—that’s maintaining at least six feet of distance between you and other non-vaccinated people
  • Wash your hands regularly
  • Get a flu shot—flu shots can protect you from other types of serious illness that may require hospitalization.

Why do the COVID-19 vaccines have to be stored in such cold temperatures?

The Pfizer and Moderna vaccines are what’s known as mRNA vaccines. They contain many enzymes which can easily break the vaccine apart and destroy it in warmer temperatures. The extreme cold slows this process down significantly, which keeps the vaccines stable and “fresh” longer.

Johnson & Johnson is producing a viral vector vaccine, which uses a harmless cold virus to deliver COVID-fighting information to your immune system. Like many other vaccines that use this technology, it can safely be stored with regular refrigeration.

How many COVID-19 vaccines and treatments are currently being developed around the world?

The Milken Institute has developed a site that tracks the development of treatments and vaccines for COVID-19. Within the site, you can explore detailed information on each development.
