Why the WHO Does Not Expect a Vaccine Against COVID-19 to Meet Efficacy and Safety Guidelines This Year

Concerns have been raised regarding the timeline for vaccine approval by the WHO, particularly because some suggest that the urgency to have a vaccine available is leading to compromises on quality and safety. This article aims to shed light on the underlying reasons and the science behind the WHO's decision, emphasizing the importance of safety and efficacy in vaccine development.

Why Safety is the Primary Concern

The primary reason the WHO does not expect a vaccine against COVID-19 to meet its efficacy and safety guidelines for approval this year is safety. When it comes to vaccines, the effects are not always immediately apparent. Some side-effects can manifest immediately, while others can appear years later. Conducting a study for just 3 months, as some short-term studies have done, cannot yield comprehensive data on long-term side-effects.

Understanding the "Real" Concerns

Here, we delve into the real concerns surrounding a potential vaccine release. The WHO, along with other reputable scientific and medical authorities, have outlined clear protocols for vaccine development and testing. These protocols ensure that the vaccine not only works (efficacy) but also that it is safe for the vast majority of people.

Finding the Balance Between Urgency and Safety

The current political and media landscape in the United States (USA) has led some to believe that the CDC (Centers for Disease Control and Prevention) is being manipulated by political figures and real estate developers. However, these concerns are not reflective of the broader scientific community's efforts to develop a safe and effective vaccine.

The truth is, it takes time to ensure that any vaccine is both safe and effective. There are numerous steps involved in vaccine development, from initial research and testing to the extensive phase 3 trials. Even with advances in technology and collaboration among pharmaceutical companies, the detailed and rigorous testing required cannot be shortened in the hope of achieving a rapid release.

Why Time is Critical in Vaccine Development

The process of developing and testing a vaccine is akin to baking a cake. Just as having more chefs does not make a cake bake faster, having more resources and manpower does not necessarily speed up the scientific process. Safety and thoroughness are paramount, as a rushed vaccine could pose significant risks.

Furthermore, the historical record of vaccine development shows that the current record for developing, testing, and approving a new vaccine stands at approximately four years. This time frame reflects the rigorous standards and extensive testing required to ensure safety and efficacy. Setting an ambitious target to achieve this within a shorter timeframe is unrealistic.

Conclusion

It is crucial to understand that the delay in vaccine approval is not due to the WHO's sinister motives but rather due to the scientific and medical principles that must be adhered to. These principles prioritize the safety and well-being of the public. In the coming months, continued research and collaboration will be key in developing a safe and effective vaccine against COVID-19.
