Pfizer asks FDA to authorize 2nd Covid booster for people 65 and older

On Tuesday Pfizer and BioNTech announced that they are planning to ask the Food and Drug Administration to authorize a second COVID-19 booster shot for people 65 and older.

The companies would plan to seek authorization for this additional booster for older adults to protect them even more against the omicron variant, reports say.

If authorized, the second booster would bring the vaccination schedule for the Pfizer vaccine to four shots in this age group.

Some experts remain skeptical that another booster is needed yet and question how effective another shot may be. Others say boosting the most vulnerable is important.
