Maybe fully vaccinated does not mean fully vaccinated.

Pfizer said last week data from Israel suggest “a third dose may be needed within six to 12 months after full vaccination.

” The company did not release the data, saying only that a scientific article based on the results has been submitted to a peer-reviewed journal for publication.

The Food and Drug Administration and the Centers for Disease Control and Prevention immediately pushed back, insisting that people who are fully vaccinated do not need a booster shot at this time. Pfizer is reportedly briefing key U.S. government entities on the data on Monday.

But WHO officials said they have seen no evidence to date that supports the idea that people who are considered fully vaccinated will need additional doses so soon.

“It may well be that you need boosters after a year or two years. But at this point, at six months after the primary dose, there doesn’t seem to be any indication,” said Soumya Swaminathan, the agency’s chief scientist.

The Spanish government has decided to spend lots of the taxpayers money on booster jabs for 2022 and 2023.

En una entrevista en Onda Cero, Darias ha anunciado que se ha suscrito contratos por importe de 1.800 millones de euros con Pfizer y cerca de 480 millones con Moderna para recibir dosis de vacunas en 2022 y 2023. Concretamente, España recibirá terceras dosis o booster.

If one needs an endless amount of booster jabs, then one can question how efficient the Coronavirus vaccines are.

While many people have bragged about being “fully vaccinated” after taking two COVID-19 jabs, a Swedish professor says that as many as five shots may be needed to combat falling immunity.

“After receiving the second dose, the immune response slowly subsides. Within a year, many may have lost their protection. We do not know yet, but if you get a third dose, it will be activated again,” he said. “Biology says that a fading immune response is not unlikely. Then it’s time for a third, fourth, maybe fifth dose”.

"Fully vaccinated" with two jabs does not seem to mean fully vaccinated, since the protectiveness of the vaccines fades.

Covid-19 vaccine booster jabs will be offered to "all Americans" from 20 September, according to US officials.

The jabs will first be given to healthcare workers, nursing home residents and older people who were vaccinated at least eight months ago.

The White House says the initiative is a response to rising infections from the Delta variant and evidence that the protectiveness of the vaccines fades.

More news showing that the effect of the vaccine is fading away:

Researchers say they are seeing some waning of protection against Covid infections in double-jabbed people.

The real-world study includes data on positive Covid PCR test results between May and July 2021 among more than a million people who had received two doses of Pfizer or AstraZeneca vaccine.

Protection after two shots of Pfizer decreased from 88% at one month to 74% at five to six months.For AstraZeneca, the fall was from 77% to 67% at four to five months.

Booster jabs every year?

However, perhaps the most pressing question of all is how long a person's newly restored immunity from their booster shot will last – and here at least, there is a strong suspicion of what is to come.

"I don't think we know that," says Humar. "But I think that that's a very real possibility. That's what it's starting to look like, especially as we see the waning antibodies and the decreased effectiveness against variants.

"Altmann could also see booster programmes eventually evolving into annual ones, however he's unsure whether the science would back it up. "I think that would be a managerial logistics decision, not an immunological decision," he says, explaining that it seems unlikely population immunity – with all the antibodies and T cells that involves – would be low enough to justify it.
