A study published in NEJM on Wednesday night found that people aged 60 and over who received a fourth dose of the coronavirus vaccine were significantly less likely to become infected and seriously ill.
Patients who received a second booster shot two weeks to a month later were 52 percent less likely to become infected than those who received a third dose at least four months earlier.
Patients were also 61 percent less likely to show signs of infection, 72 percent less likely to be hospitalized, 64 percent less likely to have a serious illness, and 76 percent less likely to die than those who only took the third dose. At least four months ago.
This is the first study to evaluate the effectiveness of the fourth dose in preventing all types of coronavirus disease.
The investigation looked at data from 182,122 people aged 60 and over who received the fourth dose. The study also looked at data from a control group of 182,122 patients of the same age who ate a third dose at least four months before receiving the fourth dose.
PCR test rates were comparable in both groups.
The research was led by Dr. Uri Magen, Dr. Jacob Waxman, and Dr. Maya Makov Asif, all of whom specialize in public health in the innovation framework of Clyllit. The study looked at data from January 3, 2022 to February 18, 2022, when the Israeli Omicron variant was in vogue.
According to Professor Ran Balisar, “The results of the fourth vaccine for 60-year-olds and older clearly demonstrate that the fourth-dose dose significantly protects against complications of coronavirus disease – including a fourfold reduction in the risk of death compared to those who received the third dose more than 4 months ago. “
Balisar added: “In our estimation, the results of the study will allow the elderly population and people at risk of complications of the disease to choose to be vaccinated with a fourth dose, in any country in the world where the virus is spreading.”
Another study published in the peer-reviewed academic journal The New England Journal of Medicine earlier this month suggests that a fourth dose of the COVID-19 vaccine may provide effective protection against serious illness in people 60 years of age or older.
According to a study published in March by Sheba Medical Center, the fourth dose of the vaccine provides slightly more protection against infection in young and healthy individuals than the first three doses, where it provides moderate protection against notable infections.
According to a Clit study published in March, the fourth dose reduced COVID-19-induced deaths by 78 percent in people aged 60 to 100 years.
