The Biden administration is pushing for Americans to get their updated COVID-19 booster shots ahead of the holidays.

"You can't see it, but you can hear it!" the graphic warned with bolded lettering. "Get your annual COVID vaccine shot before Halloween, and avoid a spooky Thanksgiving."

The push is in preparation for any possible surge in cases and hospitalizations in the winter months.

More than 20 million people in the United States have received an updated COVID vaccine through last week. The vaccine has been reformulated to target the BA.4 and BA.5 subvariants of omicron, the most dominant strains in the United States.
