Experts warn: a poorly effective vaccine will exacerbate the "Corona" epidemic and may make it "worse"
The global rush to find a vaccine for the virus could make the epidemic worse.
Experts say the global rush to find a vaccine for the "Corona" virus, could make the epidemic worse. The race continues to immunize the world against "Covid 19", which has already killed more than 850,000 people, but scientists have called on politicians and businesses to be careful.
Experts say that without comprehensive results showing at least 30-50% effectiveness, vaccines run the risk of doing more harm than good.
British ministers recently unveiled a set of measures designed to accelerate the deployment of any potential vaccine for the virus in the United Kingdom. Changing the temporary law could give any vaccine the green light, to be distributed to the British without going through the product approval system.
Scientists in Oxford involved in developing a vaccine said that they hope to obtain a treatment ready for examination by the regulators, before 2021. US President Donald Trump wants a vaccine, before the presidential elections, in November. However, Professor Richard Pitto, of the University of Oxford and a consultant to the World Health Organization, said that the initial vaccine with low efficacy would affect the standards and lead to more lower quality vaccines in the future.
He added, "I think there is a big rush, which is a nationalist rush to some extent, and a capitalist rush, also, for those who are the first to register a vaccine, and that will make it more difficult to evaluate other vaccines."
And while a vaccine is needed soon, the British scientist says, "We really need very strong evidence of effectiveness." Professor Beto is a member of the WHO's Vaccine Expert Group, which warned last week that a bad vaccine could be worse than none at all.
The group told the Lancet medical journal, “A poorly effective vaccine could actually exacerbate the Covid-19 pandemic, if the authorities mistakenly assume that it contributes to a significant reduction in risk, or if vaccinated individuals mistakenly believe they are immune, and thus lack of interest. Implement or comply with other protective measures. "
And they indicated that they would prefer trials that evaluate multiple vaccines, all over the world, as part of a common control group, rather than as individual trials. The UK government has insisted that no drug will be passed on unless it meets "the highest standards of safety and quality" and will put in place "enhanced safeguards".
