A new COVID vaccine will now be available in the U.S. after health officials recommended it Tuesday.

In contrast, the Novavax vaccine injects copies of the spike protein that are grown in a lab and packaged into nanoparticles that to the immune system resemble a virus. Another difference: An ingredient called an adjuvant, that’s made from the bark of a South American tree, is added to help rev up that immune response.

“We really need to focus on that population,” said CDC adviser Dr. Oliver Brooks, past president of the National Medical Association. Hopefully, the vaccine"will change them over from being unvaccinated to vaccinated.” Typical vaccine reactions were mild, including arm pain and fatigue, but regulators did warn about the possibility of a rare risk, heart inflammation, that also has been seen with the Pfizer and Moderna vaccines, mostly in teen boys or young men.

According to the company,"serious and severe adverse events were low in number and balanced between vaccine and placebo groups" during clinical trials.
