As Pfizer’s point of warning pointed out, a vaccine study shows the critical need for boosters.
RESEARCHERS looking into the effectiveness of the Pfizer-BioNTech vaccine discovered that the risk of Covid infection rises as time passes since the second shot.
According to a new study published in the British Medical Journal (BMJ), protection against the coronavirus deteriorates over time, necessitating a third, booster shot.
The study looked at the risk of Covid infection 90 days after people received their second Pfizer vaccine dose.
It was carried out by Israel’s Leumit Health Services Research Institute.
The World Health Organization (WHO) has reported more than 1.3 million Covid cases and over 8,000 deaths in Israel since the pandemic began in late 2019.
In December 2020, the country became one of the first in the world to implement a comprehensive vaccine program, leading to a relaxation of restrictions earlier this year.
Despite Israel’s best efforts to stop the virus from spreading, infections have increased dramatically since June 2021.
Immunity to the virus provided by vaccines is thought to wane over time, according to scientists.
The emergence of more transmissible Covid variants, such as Delta, has put additional strain on health care systems around the world.
The new study found that the Pfizer vaccine provides excellent protection against the virus in the first few weeks after it is given.
However, the findings also suggest that some people’s protection will wane over time.
Booster shots are already available in countries such as the United States, the United Kingdom, and Israel to help people strengthen their immune systems.
Dr. Anthony Fauci, an infectious disease expert in the United States, has urged the “overwhelming majority” of vaccinated Americans to get a booster shot.
Booster shots are available on the NHS in the United Kingdom for people aged 40 and up, as well as frontline workers and those who live and work in care homes.
The Israeli researchers hope that their research will help countries better understand the need for a third vaccination and when it should be administered.
Their research looked at the medical records of over 80,000 adults, who were on average 44 years old at the time.
None of the people had ever tested positive for COVID-19 before, so they were given a PCR test three weeks after their second dose of the vaccine.
7,973 (or 9.6%) of the 80,057 participants tested positive.
