What You Should Know About the COVID-19 Vaccines

Millions of people in the United States have been vaccinated. That number grows every day. We can all breathe a sigh of relief, right?

Not so fast. The vaccine story isn’t simple – at least not for coronavirus. And that’s because viruses can have variants – the first strain vaccines were created to fight – often change.

Just as the common flu virus changes each year, the COVID virus is changing, too – but much faster. The Center for Disease Control and Prevention (CDC) tracks these changes.

New variants can be more infectious. It can cause more severe symptoms or spread more easily.

Even if you go the COVID shot, you may need a booster to get more protection.

A New Focus on Omicron

For the first time, a COVID-19 booster has been formulated with elements from more than one variant. The bivalent booster has BA.4 and BA.5 spike proteins – subvariants of Omicron that make it so potent.

It also contains elements of the Alpha variant used in the original vaccine and boosters.  

“The updated COVID-19 boosters are formulated to better protect against the most recently circulating COVID-19 variant. They can help restore protection that has waned since previous vaccination and were designed to provide broader protection against newer variants,” Centers for Disease Control and Prevention Director (CDC) Rochelle P. Walensky, M.D., M.P.H., explains in a media statement from the CDC.

A CDC study of the new bivalent booster reveals it offers about 40% to 60% protection against symptomatic infection. This means people may still be vulnerable to breakthrough infections.

“Unfortunately, the 90% to 100% protection was what we saw during the pre-Delta time,” says Dr. Ruth Link-Gelles, an epidemiologist with the CDC. With Delta, we saw it drop into the 70% range, and then for Omicron, we saw it drop even lower, to the 50% range.”

Link-Gelles encourages people to use a layered approach when fighting the virus. Along with vaccines and booster shots, rapid tests, quality masks and good ventilation in inside spaces can all help find off COVID-19.

Things to Know

The vaccine may be updated again in the future. New variants may need a different version of the vaccine, so stay up-to-date on news about coronavirus.

Safety is a top priority. The Food and Drug Administration (FDA) uses a set of standards to measure the safety and effectiveness of vaccines. The COVID-19 vaccines are approved by the FDA. Talk with your doctor to see if it’s right for you.

You can get the vaccine at many places. COVID-19 shots are offered in many local health clinics, neighborhood pharmacies, and even some grocery stores. Ask your doctor or community health center if they provide vaccines. The CDC website – vaccines.gov  – can point you to a provider. You can also text your ZIP code to 438829 or call 1-800-232-0233.

You may need more than one shot. Some of the COVID-19 vaccines call for two or more doses for the most protection. The safest plan is to get all of your vaccines in the series from the same provider. Once you get your first dose, ask about when you should get your follow-up doses.
