Thousands of Israelis test POSITIVE for Covid-19 despite receiving Pfizer/BioNTech jab

More than 12,400 people in Israel have tested positive for coronavirus after being vaccinated with the Pfizer/BioNTech jab, including 69 who had received their second dose, the country's Health Ministry said.

Some 189,000 people were tested for Covid-19 after being vaccinated, with 6.6 percent getting a positive result, according to ministry data reported by Israeli outlets. The majority were apparently infected shortly after receiving the first jab of the two-part vaccine – a period when the inoculation isn't expected to have kicked in yet.

However, 1,410 people tested positive two weeks after their first injection, by which time partial immunity should have already taken effect.

Moreover, 69 patients became infected with the novel coronavirus despite already having been administered both shots of the vaccine, the ministry said. Israel began administering the second doses almost two weeks ago, with Prime Minister Benjamin Netanyahu being the first to complete the course.

Pfizer has said that a spike in immunity occurs between Day 15 and Day 21 after the first jab, when the effectiveness of its vaccine increases from 52 to 89 percent. According to earlier trials, the protection offered by the vaccine reaches the 95 percent level a week after the second dose is administered, the pharma giant said.

When it comes to vaccines, the results of clinical trials may differ from how the immunization performs in the field, where it's administered to a much greater number of people.

Hundreds of Israelis get infected with Covid-19 after receiving Pfizer/BioNTech vaccine – reports
With the vaccine not providing immediate immunity to the coronavirus, over two hundred Israeli citizens have been diagnosed with the disease days after getting the Pfizer/BioNTech jabs, local media reported.

The number of those who got Covid-19 despite being vaccinated was at around 240 people, according to data from Channel 13 News.

The Pfizer/BioNTech vaccine, which the Israeli health authorities rely on, doesn’t contain the coronavirus and can’t infect the recipient. But time is needed for the genetic code in the drug to train the immune system to recognize and attack the disease.

The course of the US-made vaccine requires two shots. According to the studies, immunity to Covid-19 increases only eight to ten days after the first injection and eventually reaches 50 percent.

The second jab is administered 21 days from the first one, while the declared immunity of 95 percent is achieved only a week after that. And, of course, there’s still a five percent chance of getting infected even if the vaccine is at its full potential.
