Gates told NBC that normalcy can return “when we have, not the first generation of vaccines, but one that is super-effective”. He also said that the second generation vaccine should also be widely available. “Only then all the problems created by Covid-19 can be solved,” he added.
Gates’ comments come as the world is racing towards finding a vaccine for the coronavirus disease (Covid-19) which has affected millions across the globe.
AstraZeneca’s experimental Covid-19 vaccine is one of the most advanced candidates in the race against the novel coronavirus.
Developed by the University of Oxford and licensed to AstraZeneca in April, the vaccine is expected to be one of the first from big pharma to secure regulatory approval, along with Pfizer and BioNTech’s candidate.
Pfizer has, meanwhile, again modified the protocol for its late-stage study of its vaccine, this time to include more young participants.
New York-based Pfizer originally planned for 30,000 participants, but in September expanded that to 44,000 people. Pfizer’s trial also includes significant numbers of Hispanic, Black, Asian and Native American participants, plus many people aged 56 through 85.
Last month, in an email interview to Hindustan Times, Gates had spoken about vaccine development and the protection it will provide. “It’s too soon to make predictions about how long protection might last. At this point, we don’t have enough data on the duration of antibody and T-cell response to the disease itself, let alone to the various vaccine candidates. Many of the vaccine trials underway should start to report efficacy data in the next few months, which will start to provide answers to these critical questions,” Gates had said.
“The good news is that there is a large portfolio of vaccines in testing, each with a different approach. This gives the greatest possible chance to develop effective vaccines,” he had further said.
On October 6, he had said that rich countries could be back to close to normal by late 2021 if a Covid-19 vaccine works, is ready soon and distributed properly at scale.
