New research: Alarming decrease in blood antibody levels in people vaccinated with pfizer


by Ifi Reporter Category:Health Mar 31, 2021

A serological test research done for Sheba Hospital staff  who received the Pfizer vaccine revealed a  significant decrease in their share of  blood antibody levels, a few months after receiving the second vaccine. It is now being investigated whether other measures in the blood may indicate that the vaccines are still efficient.
The research team led by Professor Gili Regev-Yohai is examining whether the effectiveness of the vaccine is declining. The hospital said "we are not sure this decline has any significance". One of the study participants reported that two weeks after the second vaccination the antibody levels were much higher than the threshold set that defined it as vaccinated. One month after the second vaccine the levels dropped by a third and on the third test a month later they dropped to only a third of the level measured after the second vaccine. Data from the Ministry of Health indicate that the number of patients who received two doses of vaccine has recently increased. The public may need to receive a booster dose to strengthen the antibodies each year.

The Ministry of Health has updated that for the first time since the start of the traffic light model, there are no red cities in Israel. While a score of 7.5 or higher refers to a city that is a center of morbidity, the locality with the highest score today is the regional council Kawb Abu al-Higa in the north, with 7.3.
356 people have been diagnosed with Corona in the past day. This increased the number of verified in Israel to 832,467.

The rate of verified yesterday was 1.4% and in Israel there is only one locality that is defined as "red", but in the last three days there has been a decrease in the rate of vaccinators. The coefficient of infection increases at a moderate rate and stands at 0.6.

 From Friday to Sunday morning, 807 verified corona were diagnosed in Israel. Data from the Ministry of Health show that 60 verified patients have been diagnosed so far, yesterday 229 (1.4% of about 15,000 tests were positive) and on Friday 518 (1.1% of about 47,000 tests were positive).

In the last three days, the rate of vaccinators has dropped. About 5,500 Israelis received the first dose of the vaccine since Friday and about 17,000 received the second dose of the vaccine. The data show that more than 5.2 million Israelis received the first vaccine dose and more than 4.7 million also the second.
