Pfizer is offering more proof of why its COVID booster shots are needed. A new study shows protection drops to 47-percent six months after being fully vaccinated. But with the delta variant, it’s only 53-percent effective after four months.

Still, researchers point out the vaccine has proven to keep more patients out of the hospital, fighting off all other strains. An FDA hearing next week will focus on boosters for Moderna and Johnson and Johnson.
