According to a research led by Case Western Reserve University and Brown University, the Covid-19 antibodies produced by the Pfizer vaccine decreased more than 80 percent in many people including senior nursing home residents, six months after receiving the vaccine. The researchers studied the blood samples of 120 nursing home residents and 92 health care workers. This justifies the call for a booster shot by the CDC.
