Israel’s coronavirus czar Nachman Ash has reportedly said the first dose of Pfizer’s vaccine provides less protection against COVID-19 than the US pharmaceutical firm had initially indicated it would, and cautioned that it may not protect against new strains of the virus.
During talks among Health Ministry officials ahead of Tuesday’s cabinet meeting on the possibility of extending the nationwide lockdown, Ash questioned the effectiveness of the vaccine after just one dose, Army Radio reported Tuesday afternoon.
Many people have gotten infected between the first and second Pfizer shots, Ash was quoted saying, and it appears that the protection offered by the first dose is “less effective than we had thought.” The data on the protective effect against the virus of the first dose is “lower than Pfizer presented,” he was quoted saying.

So basically not only Pfizer's mRNA kill patients, but also, its so-called efficiency number is a basically a bogus claim, no wonder experts questioned their numbers now.
From their open data, it can be deduced the efficiency number could be anywhere between 19% to 95% as Pfizer claimed, to believe exact what efficiency number is depend on your faith in the US, for these faithful believers in PDF, the efficiency number could be as high as 195% efficient.
Umm it says first dose, didn't include results after second dose. Theres a reason why they say to have two shots, not one. This guy didn't read the manual.
Your source says this,
Pfizer says its vaccine, produced with BioNTech, is around 52% effective after the first dose, and increases to about 95% a number of days after the second dose.
Last week, Sharon Alroy-Preis, head of the Health Ministry’s public health department, announced that the vaccine curbs infections by some 50 percent 14 days after the first of two shots is administered. She said that the data was preliminary, and based on the results of coronavirus tests among both those who have received the vaccine and those who haven’t, who are are serving as a de facto control group.
At the same time, however, other, somewhat contrary data was released by Israeli health maintenance organizations: According to figures released by Clalit, Israel’s largest health provider, the chance of a person being infected with the coronavirus dropped by 33% 14 days after they were vaccinated; separate figures recorded by the Maccabi health provider showed the vaccine caused a 60% drop in the chances for infection after taking the first shot.
During his talks with health officials on Tuesday, Ash also said that it was not certain the vaccine can protect against mutated variants of the coronavirus, according to the report.

Why Do I Need the Second COVID-19 Vaccine Shot?
Key takeaways:
- Some vaccines need two shots to be most effective. In studies, Pfizer’s vaccine was 52% effective after the first shot and 95% after the second one.
- We don’t know how effective a single shot for the vaccine would be in the long run or how long the immunity would last.
- It’s also unclear how effective the vaccine is if you don’t follow the exact dosing timeline.
The number of hospitalizations and deaths from COVID-19 continues to rise at an alarming rate. But 9 months into the pandemic, there’s finally some good news: Several effective COVID-19 vaccines have been developed. The vaccine from Pfizer and BioNTech was just approved in different countries,
including the U.S., and some people have already started to get vaccinated.
As these vaccines become more available, there are many questions about how well they work and how safe they are. And one common question is a good one: Why does the COVID-19 vaccine require two shots?
Here we discuss what we know about how the COVID-19 vaccine is used, how effective it is, and why it’s important that you get the second shot.
Do all the COVID vaccines in development require two shots?
No — but many of them do.
Pfizer developed the first approved COVID-19 vaccine, and their vaccine requires two shots that
are spaced 21 days apart. Another
COVID-19 vaccine from Moderna is not far behind and will probably be approved soon. It also needs two shots, but they
are spaced 28 days apart.
In the U.S.,
five other vaccines are being planned for or being studied in phase 3 clinical trials (the last phase before approval). Of those, only
one will need one shot — the other four will need two shots.
Keep in mind that it’s not uncommon for vaccines to require two, three or sometimes even four doses in order to be most effective. In fact, this is true
for many of the first vaccines given to children, like hepatitis B, diphtheria, and tetanus.
Right now, there are
about 230 COVID-19 vaccines being developed around the world. It’s possible that some of those will only require one shot. Studies will need to be done to see which ones (if any) will be effective after just a single dose.
How effective is the first COVID-19 vaccine shot?
When a vaccine requires two shots, the
first shot helps your body recognize the virus and gets your immune system ready, while the second shot strengthens that immune response. This makes your body more prepared to fight infection. Learn more about how vaccines work
here.
In the studies for Pfizer’s vaccine, the first shot seemed to be
about 52% effective in preventing COVID. The second shot increased that effectiveness to 95%. Since people got two shots in the studies, we don’t know how effective a single shot would be in the long run or how long it would last.
After getting the first shot, it can take up to a
few weeks for your body to develop the cells that will make you immune. This means that it’s possible for you to get sick (infected) during that time. So it’s important to continue wearing masks and practicing social distancing even after getting the vaccine.
