A top World Health Organization (WHO) expert stressed that public trust is crucial for the success of COVID-19 vaccines in combating the pandemic.
Kate O'Brien, director of WHO's immunization department, warned that even highly effective vaccines would be ineffective if people refuse to use them.
She acknowledged the promising interim results from Pfizer and BioNTech's vaccine candidate, which reported 90% efficacy.
O'Brien expressed hope for similar positive outcomes from other advanced vaccine trials currently underway.
However, she voiced significant concern over rising vaccine hesitancy, fueled by misinformation and distrust, which could hinder global efforts to end the pandemic that has already claimed 1.3 million lives.
