Pfizer wax antibody levels drop down to percent percent after months: study

New York: The antibodies produced by the Pfizer vaccine against Covid-1 have dropped by more than 100 percent in some older people after six months. Researchers at Case Western Reserve, Brown and Harvard University studied the blood tests of 120 Ohio nursing home residents and 92 healthcare workers.

In particular, they measure humoral immunity, also known as antibody-mediated immunity, to measure the body’s defenses against coronavirus.

The results, published online in MedRxiv and Peer-Review, showed that individuals’ antibody levels dropped by more than 80 percent after six months.

The team submits its unpublished results directly to the CDC and urges them to bring the data into the public domain as soon as possible so that we can enter the negotiation and decision-making process for booster vaccine recommendations, Kennedy said.

Acute decline is particularly problematic for the elderly because previous studies in the Case Reserve have shown that full vaccination is being considered and within two weeks of receiving the second dose of the vaccine. Older adults who have not previously contracted Covid-1 contract have already shown less response to the antibody than experienced young caregivers.

Six months after the vaccination, blood laboratory tests for percent of the residents of this nursing home showed very little ability to neutralize coronavirus infection, Kennedy said.
