Why does Israel start the fourth shot of COVID-19 vaccines?
Israel, which has been leading the way in the field of COVID-19 vaccination, will become the first country in the world to provide the fourth shot.
According to the US “New York Times” report, on the 21st local time, Israeli Prime Minister Bennett announced that the country’s health agencies will begin to provide the fourth dose of the COVID-19 vaccine to people over 60 years old and medical staff, which will help cope with the Omicron mutation.
The challenge posed by the virus strain. However, experts interviewed by a reporter from the Global Times on the 22nd all believed that due to the bottleneck of vaccination rates and insufficient public health measures, Israel’s fourth injection program is difficult to achieve the expected results.
With the rapid spread of Omicron mutant strains in many places around the world, many governments have begun to introduce new epidemic prevention measures. Israel’s choice is to strengthen the vaccine on the basis of booster shots.
Bennett said on the 21st that the expert team of the Ministry of Health of the country has recommended the fourth dose of vaccination.
He himself also said, “Don’t waste time, go get vaccinated.” According to CNN, people over 60, medical workers, and people with immunodeficiency are eligible for the fourth dose, but only if they have completed the third dose for at least 4 months.
On the day Israel announced the above news, a hospital in that country reported its first death from Omicron infection.
According to reports, the death of the elderly patient was largely due to his own multiple underlying diseases. He had previously received two doses of Pfizer vaccine.
According to data released by the Israeli Ministry of Health on the 21st, in the past 24 hours, a total of 1,306 cases of COVID-19 cases have been reported in the country.
As of that day, Israel has reported at least 340 cases of Omicron infection and about 800 suspected cases. These may be factors that have accelerated Israel’s fourth shot.
Although Israel has already made the decision, Professor Galia Rahafer, a member of the expert panel of the Ministry of Health of the country, admitted in an interview with the media, “We have not really got the data on the level of immunity, just like we did when we decided to get the third dose.
But on the other hand, the data for (Omi Kejon infection) in other parts of the world is really scary. In this case, if you don’t take immediate action, you will miss the train.”
Last week, an Israeli hospital announced that it would start a clinical trial to test the effects of the fourth dose of Pfizer vaccine.
Israel is one of the first countries in the world to initiate the third booster injection, and once reopened the society by issuing “vaccine passports”, but Chen Xi, an associate professor at the Yale School of Public Health who was interviewed by a Global Times reporter on the 22nd, pointed out For reasons such as religion and vaccine skepticism, Israel’s vaccination rate has never exceeded 70%.
The same situation will also appear in the advancement of intensive injections. People who were previously unwilling to be vaccinated will still not be vaccinated, and the fourth injection will still not fundamentally change Israel’s epidemic prevention problems.
Israeli media reports also show that only about 4.1 million people in this country with a population of 9.3 million have completed the three-shot vaccination, and the vaccination rate for children aged 5-11 is very low.
A domestic immunologist told the Global Times reporter that it is not that the more vaccinations, the better the immune effect.
From the principle of immunology, multiple vaccination of the same vaccine will make the immune response of the human immune system to the vaccine more and more specific, and the main sites of the response may be reduced, making it more difficult to induce the immune response. Identify and protect the body from infection by mutant strains.
The unnamed expert believes that China’s “dynamic zero” policy can be used for reference to Israel, which has a small land area and strict border management.
An Israeli living in Jerusalem told the Global Times reporter on the 22nd that Israel does not have a “dynamic zeroing” policy, mainly because the economic cost is too high, and the Israelis themselves do not accept such measures.
It is better to take the initiative to vaccinate. vaccine. “My two children were vaccinated for the first time, and the doctors also recommended the children to be vaccinated.” He said that the most worried thing is still the heavy economic damage caused by the continued existence of the virus.
