WASHINGTON (CBSLA/AP) — A panel from the Food and Drug Administration endorsed booster doses of Johnson & Johnson's COVID-19 vaccine. 

The FDA panel recommended booster shots should be offered at least two months after immunization but did not suggest a firm time. While the panel endorsed, the Johnson & Johnson booster shots, it still awaits full approval from the FDA.

An FDA advisory panel endorsed the Moderna vaccine last night and the FDA approved booster doses of the Pfizer vaccine last month. 

About 69% of Los Angeles County residents have received at least one dose and 62% are fully vaccinated.
