Talking of uncertainties at hand owing to the assumption of a perfect vaccine coming into force, on August 3, the World Health Organization has warned that there might never be a “silver bullet” for COVID-19 in the form of a perfect vaccine.
The WHO added that the road to normalcy would be long and advised that some countries will be required to reset their strategy to fight the pandemic in the long run.
WHO Director-General Dr. Tedros Adhanom Ghebreyesus has asked nations to rigorously enforce health measures such as mask-wearing, physical distancing, hand-washing and testing. Dr. Tedros Adhanom Ghebreyesus said, “The message to people and governments is clear: ‘Do it all’.”
Speaking of the potential vaccine he added, “A number of vaccines are now in phase three clinical trials and we all hope to have a number of effective vaccines that can help prevent people from infection. However, there’s no silver bullet at the moment – and there might never be.”
“There are concerns that we may not have a vaccine that may work, or its protection could be for just a few months, not more. But until we finish the clinical trials, we will not know,” he said.
The WHO Chief said that, while the coronavirus was the biggest health emergency since the early 20th century, the international scramble for a vaccine was also “unprecedented”.
