Many countries start to vaccinate specific populations with new crown vaccine booster |
Xinhua News Agency, Beijing, September 25.
With the spread of the new coronavirus mutation, the opening of schools in various places, and the upcoming autumn and winter seasons of respiratory diseases in the northern hemisphere, some countries have decided or have begun to vaccinate specific populations with a higher risk of new crown infections.
.
The US Food and Drug Administration amended the emergency use authorization for Pfizer's new crown vaccine on the 22nd, allowing elderly and high-risk groups to receive a booster dose of Pfizer vaccine at least 6 months after receiving the second dose of Pfizer vaccine
.
The U.
S.
Drug Administration explained that the elderly refer to people 65 years of age and older, and the high-risk group refers to people at risk of severe illness and people at risk of occupational exposure between 18 and 64 years old
.
The British government began to implement the new crown vaccine booster plan on the 16th to provide front-line medical staff, nursing facility staff, people over the age of 50, and people over 16 with health problems with a booster injection of the new crown vaccine
.
The enhanced needle plan is part of the "Responding to the New Crown Epidemic: Autumn and Winter Plan" recently announced by the United Kingdom
.
According to the regulations of the British government, people who are eligible for vaccination can only receive booster shots at least 6 months after receiving the second dose of the new crown vaccine

Israel began to carry out the new crown vaccine booster vaccination in phases from mid-July, mainly using Pfizer vaccine
.
The country began vaccinating booster shots for adults with cancer or immune system compromised such as those who have undergone organ transplant operations on July 12, and boosted vaccinations for people over 60 years old on July 30, and boosted up on August 29.
The Austrian state of Lower Austria has been vaccinating high-risk groups with booster shots of the new crown vaccine since August 30, making the state the first Austrian state to start boosting shots
.
In addition, the Austrian government began to prepare for the expansion of the scope of intensified vaccination in the fall
From September 20th, Italy's elderly, people with weakened immune system and medical staff can be vaccinated with the new crown vaccine booster
.
The elderly and those with weakened immune systems in Malta can receive booster shots from September 6
Other countries also intend to vaccinate certain groups of people with booster shots
.
French President Macron said on August 11 that after the holiday season, France will vaccinate the new crown vaccine booster for people over 80 years old and high-risk groups with extremely vulnerable immune systems
Official
Why do you need a booster shot? This is because the protective effect of the vaccine may diminish over time, and it is necessary to vaccinate again in order to provide additional protection
.
Another reason is virus mutation
Two preprinted research papers recently published by Israeli researchers show that vaccination with Pfizer's new crown vaccine booster can significantly reduce the risk of new crown virus infection
.
One of the results of a study showed that booster vaccination can increase the protective effect of preventing infection by up to 5 times
