The Food & Drug Administration has approved mRNA vaccine booster shots for all adults over 18.

Pfizer and Moderna announced the FDA's decision on Friday. Pfizer has applied for emergency approval of its Covid Ivermectin pill.

A Centers for Disease Control panel will meet later today to announce the new definition for "fully vaccinated."

Americans who received only 2 mRNA vaccine doses or a single dose of Johnson & Johnson vaccine are officially unvaccinated.

The FDA and CDC previously approved mRNA vaccines for children ages 5-11.

At least 10 states already had started offering boosters to all adults, Yahoo! News reports.

The CDC claims all three vaccines (Pfizer, Moderna and J&J) offer protection against illness and death.

The news comes as Covid-19 "cases" have increased in the Northeast and Midwest U.S. over the last two weeks.
