Why we can't 'boost' our way out of the COVID-19 pandemic for the long term
...
the vaccines have failed to provide long-term protective immunity to prevent breakthrough infections – cases of COVID-19 infection that occur in people who are fully vaccinated.

Because of this, the Centers for Disease Control and Prevention recently endorsed a second booster shot for individuals 50 years of age and older and people who are immunocompromised. Other countries including Israel, the U.K. and South Korea have also approved a second booster.

However, it has become increasingly clear that the second booster does not provide long-lasting protection against breakthrough infections.
...
While the third dose – or first booster – of COVID-19 vaccines was highly effective in preventing the severe form of COVID-19, the protection afforded against infection lasted for less than four to six months.

That diminished protection even after the third dose is what led the CDC to endorse the fourth shot of COVID-19 vaccine – called the second booster – for people who are immunocompromised and those aged 50 and older.

However, a recent preliminary study from Israel that has not yet been peer-reviewed showed that the second booster did not further boost the immune response but merely restored the waning immune response seen during the third dose. Also, the second booster provided little extra protection against COVID-19 when compared to the initial three doses.
...
In addition to the inability of the current COVID-19 vaccines to provide long-term immunity, some researchers believe that frequent or constant exposure to foreign molecules found in an infectious agent may cause immune “exhaustion.”

Such a phenomenon has been widely reported with HIV infection and cancer. In those cases, because the T cells “see” the foreign molecules all the time, they can get worn down and fail to rid the body of the cancer or HIV.

Evidence also suggests that in severe cases of COVID-19, the killer T cells may be exhibiting immune exhaustion and therefore be unable to mount a strong immune response.

So, with all the above information in front of them, can they now finally figure out what should be done instead? No, because they are Western medics:

the next phase of vaccine development will need to focus on how to trigger a long-lived antibody response that would last for at least a year, making it likely that COVID-19 vaccines will become an annual shot.
