Pfizer says tweaked COVID shots boost omicron protection
CBSN
Pfizer announced Saturday that tweaking its COVID-19 vaccine to better target the omicron variant is safe and works — just days before regulators debate whether to offer Americans updated booster shots this fall.
The vaccines currently used in the U.S. still offer strong protection against severe COVID-19 disease and death -- especially if people have gotten a booster dose. But those vaccines target the original coronavirus strain and their effectiveness against any infection dropped markedly when the super-contagious omicron mutant emerged.
Now with omicron's even more transmissible relatives spreading widely, the Food and Drug Administration is considering ordering a recipe change for the vaccines made by both Pfizer and rival Moderna in hopes that modified boosters could better protect against another COVID-19 surge expected this fall and winter.

The Trump administration deployed ICE and other Homeland Security agents to 14 of the nation's airports on Monday to help shuttle passengers through overcrowded TSA checkpoints. In one airport, the security line wait-time was up to six hours. Nicole Sganga and Kaia Hubbard contributed to this report. In:
