Results of human trials by Pfizer are expected as early as this month, while many other vaccine-makers expect to know whether their product works by the end of the year. She said any vaccine that is approved by the WHO under the Covax facility, an initiative of over 172 countries to procure and provide an effective vaccine to at least 20 per cent of the members’ population, has to undergo other steps before it can reach the masses. Eleven vaccines, three of them included in the Covax facility, are currently undergoing Phase Three trials, where thousands in many countries get inoculated while some receive a placebo.
Researchers also monitor subjects for any adverse side effects. They then compare the results to those who received a placebo, to see if there is any statistically significant difference in the data. She said even with the fast-tracking of the vaccine, there were certain steps that should not be removed, adding that respective countries’ approval bodies will have to test and approve it, on top of producing enough doses.
In a poll by IPSOS for the World Economic Forum, 85 percent of Malaysians surveyed said they would take a Covid-19 vaccine if one was available. About half think a vaccine will be available by the end of the year.
