Is vaccination efficient?
Alarm in the pioneering country of vaccinations
Just a week and a half after Israel terminated its mask mandate in almost all areas, the Health Ministry announced it is reimposing the requirement to wear face masks in indoor public areas, starting at noon on the 25th of June.
“Israel's coronavirus czar Dr. Nahman Ash said Thursday that Israel will reinstate its indoor mask mandate beginning Sunday, in light of the recent rise in coronavirus cases across Israel.” https://www.haaretz.com/israel-news/israel-covid-delta-variant-two-month-record-1.9935923
The reason for the new mask mandate is clarified to Haaretz by Chezy Levy, the director-general of Israel's health ministry: “When asked how many of the new coronavirus patients have been vaccinated, Levy said that "We're looking at a rate of 40 to 50 percent," and said that the figure is concerning.” https://www.haaretz.com/israel-news/israel-covid-delta-variant-two-month-record-1.9935923
So, about half of the new COVID-19 cases have occurred among the fully vaccinated. There are also reports from Israel that epidemiological tracing has revealed that many of the additional new cases of COVID-19 are people who have been infected by fully vaccinated individuals.
This would mean that not only vaccination protects the fully vaccinated person poorly. It also does not prevent a fully vaccinated person to infect others.
A recent study in Lancet (published June 3rd, 2021) has found that the Pfizer vaccine is not as efficient with new variants of viruses as with the original variant: Neutralising antibody activity against SARS-CoV-2 VOCs B.1.617.2 and B.1.351 by BNT162b2 vaccination, Emma C Wall, Mary Wu, Ruth Harvey, Gavin Kelly, Scott Warchal, Chelsea Sawyer, Rodney Daniels, Philip Hobson, Emine Hatipoglu, Yenting Ngai, Saira Hussain, Jerome Nicod, Robert Goldstone, Karen Ambrose, Steve Hindmarsh, Rupert Beale, Andrew Riddell, Steve Gamblin, Michael Howell, George Kassiotis, Vincenzo Libri, Bryan Williams, Charles Swanton, Sonia Gandhi, David LV Bauer, Published: June 03, 2021DOI: https://doi.org/10.1016/S0140-6736(21)01290-3, Neutralising antibody activity against SARS-CoV-2 VOCs B.1.617.2 and B.1.351 by BNT162b2 vaccination .
The study compared the concentrations of antibodies. Findings were that people who had been fully vaccinated with two Pfizer doses had antibodies that, when compared to the original strain, were 6 times lower against the B.1.617.2 variant (India), 5 times lower against the B.1.351 variant (South Africa) and 2.6 times lower against the B.1.1.7 variant (UK).
The study gives the impression that each new mutation that appears, or most of them, may need a new type of vaccine. It is time to start using the other methods of protection against COVID-19 that exist. Otherwise, the world's population will have to wear face masks forever and take jabs with new types of vaccines perhaps once a year or more.
