When vaccines were manufactured and distributed, not many countries were really successful. However, above all, the country with the most successful vaccination programs during the Covid-19 pandemic is not the United States or European countries, but Israel.
When most countries vaccinated less than 1% of the population, Israel exceeded 20%. And recently, according to studies conducted in this country, the Covid-19 vaccination program has really worked, as seen in the drastically reduced infection and hospitalization rates. However, the results also indicate that some vaccines, at least Pfizer / BioNtech’s, require two injections to be effective.
In the fierce race between countries around the world to ensure early access to the vaccine, Israel is indeed in a pretty strong position. They convinced Pfizer that the small population size, tightly controlled borders, and the ability to organize and track the disease would help inform the effectiveness of the vaccination program around the world as quickly as possible.
Pfizer realized this Israel advantage, so it was very supportive of the vaccination program there. The fact that previous infection rates in Israel were also above average is also a factor in the faster implementation of the program. As a result, Israel received enough vaccines to vaccinate the entire population, while the world struggled to get what it needed.
Keeping its promise to deliver early results, the Israel Ministry of Health and Maccabi Health Services have released a post-vaccination infection report. Consequently, only 31: 163,000 vaccinated people became infected within 7-16 days before receiving the second injection. Meanwhile, the other group had up to 6,500 cases in the same period.
The comparison here is not perfect, as those who inject tend to worry about and implement better prevention measures. However, that was not something that could be used to explain the 200 times difference. Times of Israel The vaccine was found to be 92% effective, slightly less than 95% in clinical trials. The numbers are truly impressive, as the Maccabi study subjects were of a higher average age than Pfizer used to be.
The target group of the Israeli Ministry of Health is larger and the results are similar. Within 1 week of the second injection, only 317 people out of a total of 715,425 tested positive for Covid-19 – 0.04%. Note that more complex indicators such as hospitalizations and deaths will be difficult to access clinical trials, making Israel’s only 16 hospital admissions (0.02%) extremely notable.
Not only were the results similar to those of the clinical trial, but what happened in Israel also matched that of Los Angeles County (USA). It is also a place where the number of cases has dropped significantly after vaccination.
In fact, the spread in Israel has slowed since January 14. However, at that time, the data could not be released, because it was not known whether it was the effectiveness of the vaccine or the other preventive measures. Because, many countries also achieve this achievement just by wearing a mask and restraining themselves.
However, Israeli data also recorded a less impressive figure from just one injection of the Pfizer / BioNtech vaccine. That is why the infection rate in this country continued to increase at that time, despite the fact that many people were vaccinated.
If your details are confirmed, this will be important information for health agencies around the world. From here, experts will know whether to use vaccines in limited quantities or to prioritize large-scale vaccines first.
