Israel: Re-infection rate 7 days after booster shot (3rd dose) was only 0.2%



Israel: Re-infection rate 7 days after booster shot (3rd dose) was only 0.2%, and Israel wanted to use a booster shot of the vaccine to replace the lockdown.

Newly released data from Israel shows that vaccines are still the best tool to fight the epidemic. Data from Israel shows that the third dose of the COVID-19 vaccine has a significant boost.

Israel began to vaccinate people over 60 years of age with booster shots on July 30. According to the data released by the Israeli Ministry of Health on August 22, the protection effect of the above-mentioned population after the booster shot was significantly better than that of the population who received only two doses of the vaccine.


Israel: Re-infection rate 7 days after booster shot (3rd dose) was only 0.2%,


In an interview with a reporter, Song Jing, a resident scientist at the Benaroya Research Institute and a PhD in Immunology from the Hebrew University of Jerusalem, Israel, said that according to the latest research, it is necessary to strengthen the focus on improving humoral immunity. And cellular immunity has an effect.

She said that research has shown that even those who have recovered from COVID-19 pneumonia, if they receive another dose of the vaccine, will strengthen their immune protection to a certain extent.

Since July, the number of confirmed cases in Israel has risen sharply. In the past week, the number of new diagnoses per day has been around 7,500, which also means that 1 out of every 150 people are diagnosed every day.

This makes Israel one of the countries with the highest rate of COVID-19 infection in the world. 



The booster shot (third dose) is effective

The data provided by the Gertner Institute and the KI Institute show that compared with the overall protection effect of 10 days after two doses of the vaccine, the overall protection of people aged 60 and over in Israel is 10 days after the booster injection The effect is 4 times higher; in terms of preventing severe and hospitalized cases, the effect is 5 to 6 times better.

The two research institutes reported the above results to the vaccine expert working group of the Israeli Ministry of Health on the 19th. On the 22nd, the Israeli Ministry of Health published the report on its website.

Specific data show that among the 1.1 million people who have received the third dose of vaccine, 2790 people are still infected with COVID-19 pneumonia 7 days after vaccination, the proportion is 0.2%. Among them, only 187 people were hospitalized, accounting for 0.01%; 88 people had severe symptoms, accounting for 0.008%; less than 15 people died, but the report did not provide specific data on deaths.

This data seems more gratifying than the preliminary data released by Maccabi, Israel’s second largest medical service organization on the 18th. Maccabi said that after the third dose of people over 60 years old, the booster injection reduced the risk of infection for people over 60 years old by 86%.

The Maccabi study analyzed nearly 150,000 people who received the third dose for more than a week. Compared with 675,000 people who received two doses between January and February, the population structure of the two comparison groups was similar. The results showed that there were 37 confirmed patients who had received the third dose, and 1064 confirmed patients after the second dose.



Use the boost shot (third dose) to resist the pressure of closing the city

The 49-year-old Israeli Prime Minister Bennett has publicly vaccinated a booster shot in a hospital on the 20th, and he called on the public to actively vaccinate. Bennett said that the vaccine is safe and effective. “If everyone gets the third dose, we can avoid the fourth round of ‘blocking the city’.”

Earlier, Israeli Minister of Health Nitzan Horowitz also stated on the 16th that vaccines are the best tool to combat the COVID-19 epidemic, and Israel has enough vaccines for vaccination. He called for speeding up the third dose of COVID-19 vaccination to avoid the implementation of the “closure of the city” measures.

Israel began vaccinating the public in December last year, giving priority to people aged 60 and over, mainly using Pfizer vaccine. The effect of vaccination was very significant at one time, and the number of new cases was drastically reduced.

According to data from the Israeli Ministry of Health, from May 2 to June 5, the effective rate of Pfizer’s vaccine in preventing COVID-19 infections in Israel was 94.3%. However, with the spread of the “Delta” strain, the effective rate of Pfizer’s vaccine against infection dropped to 64% from June 6 to July 3; from June 20 to July 17, the effective rate further dropped to 39% .

In addition, according to data released by the Israeli Ministry of Health on August 13, more than 53% of newly confirmed cases in a single day have been vaccinated with two doses, and 60% of critically ill patients have also been vaccinated.

At the same time, the Israeli Ministry of Health also stated that after a long period of time after vaccination, the protective effect of the vaccine will gradually weaken regardless of the age of the vaccinator. At present, many Israelis have been vaccinated with two doses for more than half a year.

Therefore, Israel decided to introduce a third dose to enhance the effect of immunity. On July 12 this year, Israel began to provide a third dose of COVID-19 vaccination for adults suffering from cancer and those with impaired immune systems such as organ transplants.

On July 30, Israel began to vaccinate people over 60 years of age with booster vaccination. On August 19, the target of booster vaccination was expanded to people aged 40 and above. At the same time, it is recommended that all teachers, medical staff, pregnant women and nursing home staff be vaccinated. Needle. The person receiving the booster shot must have completed two doses of vaccination for at least 5 months.

According to the latest data, of the approximately 9.3 million people in Israel, more than 5.4 million people have been vaccinated with two doses so far, and nearly 1.5 million people have been vaccinated with booster shots. Because the vaccination age is restricted to 12 years and older, about 1.5 million children in Israel cannot be vaccinated temporarily.

In addition, the United States has also announced plans to provide enhanced needle injections to all Americans, and Canada, France, and Germany have also announced their own enhanced needle programs.
