The Director General of the world Health Organization warned Monday that a vaccine alone won’t be enough to defeat the Covid-19 pandemic.
Tedros Adhanom Ghebreyesus had indicated on Twitter that he had been in contact with someone who had tested positive at Covid-19 but he had continued to perform his duties remotely.
Pfizer and BioNTech’s Vaccine Agency Prudence
Regarding the vaccine, the managing director, like several of his deputies, has in recent days tried to temper the optimism that emerged last week when Pfizer and BioNTech announced that preliminary data from phase III trials of their vaccine showed 90 percent efficacy.
“Initially, quantities will be limited and therefore health care workers, the elderly and those at risk will be given priority and we hope this will reduce the number of deaths and enable health systems to resist,” said the Executive Director.
“But this will still leave a lot of room for the virus to operate,” he warned, urging that measures to control the spread of Covid-19, such as testing, quarantine, follow-up of contact cases, etc., should not be prematurely terminated.
