The Efficacy of Current COVID-19 Vaccines: Pfizer/Moderna and the New Coronavirus Variants

Introduction

With the constant evolution of the coronavirus and the emergence of new variants, many are questioning the efficacy of the currently available vaccines, specifically Pfizer and Moderna. This article will address the concerns regarding the ability of these vaccines to protect against the new variants and older strains.

Vaccines and New Variants

The recent healthcare and scientific literature indicate that the current Pfizer and Moderna vaccines do not effectively protect against new coronavirus variants. These vaccines were initially designed to target the original strain of SARS-CoV-2; however, they do not provide the necessary protection against new variants or the older strains.

Words have meaning, and it is important to clarify that a new variant is not a completely new strain but rather a serologically identical mutation of the original strain. This means that the antibodies raised against the original strain remain effective against the new variants. Unfortunately, the vaccines need to be continually adapted to keep up with emerging mutations, which can be challenging.

Given this, the mRNA vaccines from Pfizer and Moderna can be modified to stay current with new variants, but individuals still need booster shots to maintain immunity against the disease. This ongoing requirement for boosters highlights the significant challenges in long-term immunity after vaccination.

Recent Rulings and Concerns

A recent ruling by the 9th Circuit Court of Appeals casts further doubt on the traditional medical definition of vaccines. According to this ruling, the COVID-19 shots do not meet the traditional criteria for vaccines, meaning that individuals can still become infected with the virus and transmit it to others. Additionally, the ruling suggests that these vaccines may lower the immune system, allowing for repeated infections.

Internet searches have revealed extensive information on the adverse effects of the COVID-19 vaccines and measures to prevent them, supporting the notion that the protection provided by these vaccines is not as robust as initially claimed.

Evolving Efficacy and the Need for Boosters

While the vaccines did offer significant protection when initially administered, their efficacy has waned over time. Studies show that the vaccines are not as effective today as they were at the beginning of the pandemic. However, getting booster shots that have been specifically tailored to address new variants can improve protection.

Though the vaccines may provide moderate protection currently, the evolving nature of the virus necessitates continuous adaptation and the use of booster shots to maintain adequate immunity. This ongoing need for boosters underscores the importance of understanding the limitations of current vaccines and the necessity for continued scientific research and development.

Conclusion

The current Pfizer and Moderna vaccines provide limited protection against new coronavirus variants and older strains, highlighting the ongoing challenges in vaccine efficacy. While there is still hope for improved protection through booster shots, it is crucial to stay informed about the evolving landscape of the pandemic and the efficacy of available vaccines.
