“We must prepare for a fourth injection,” warns Israel’s Covid-19 chief – third dose has already failed

By · · 3 min read

RIO DE JANEIRO, BRAZIL – Over the weekend, Prof. Salman Zarka, Israel’s health, and Covid-19 commissioner, called on the country to prepare for the “fourth dose of Pfizer vaccine” against Covid-19, as the third booster shot may have already failed.

While the number of positives in Israel continues to rise and the country has already administered a third injection of the Pfizer vaccine to 2.5 million people at risk of losing the freedom granted to the vaccinated by their “green passport,” Zarka says the virus cannot be defeated and a fourth dose will soon be needed.

“Since the virus is here to stay, we must also prepare for a fourth injection,” Salman Zarka told Kan Public Radio.

Zarka acknowledged that the vaccinations Covid will never stop and claimed that life will never return to normal, adding, “This is our life from now on, in waves.” Zarka had previously suggested that Israelis could be vaccinated more with each new “wave” of Covid-19.

This all but ensures that the controversial “green pass” system will continue to be expanded and “upgraded” indefinitely. Authorities have already indicated that this form of “vaccination passport,” which entitles the holder to enter certain public places such as restaurants, sports halls, and public places of worship, will expire depending on whether the holder has received his or her second or third dose of the vaccine.

Last month, Israeli Prime Minister Naftali Bennett declared that Pfizer’s Covid-19 vaccine had “faded” and urged Israelis to get a third dose “quickly.” It is unclear when Bennett will begin asking the Israelis to line up for their fourth dose.

In the meantime, Pfizer is busy developing a twice-daily COVID-19 pill that the company’s chief executive says is needed alongside vaccines to combat the virus.

HARVARD EPIDEMIOLOGIST SAY NEW SCIENTIFIC FINDINGS MAKE COVID VACCINATION PASSPORTS INCORRECT AND DISCRIMINATORY

Harvard Medical School professor Martin Kulldorff said research showing that natural immunity offers exponentially more protection than vaccines means that vaccine passports are unscientific and discriminatory because they disproportionately affect working-class people.

“Previous Covid disease (lots of working-class) provides better immunity than vaccines (lots of professionals), so vaccine mandates are not only scientific nonsense, they are also discriminatory and unethical,” observed Kulldorff, a biostatistician, and epidemiologist, on Twitter.

Different studies, including one from Israel, show that natural immunity – gained by having had Covid-19 – offers better protection against a recurrence than vaccines.

Moreover, CDC’s own research shows that vaccinated people still get infected with Covid-19 and carry viral loads like unvaccinated people.

“The high viral loads suggest an increased risk of transmission and raised concerns that, unlike other variants, vaccinated persons infected with Delta can transmit the virus,” said Rochelle Walensky, director of the CDC.
