British pharmaceutical giant AstraZeneca said on Monday that its vaccine for Covid-19 could be up to 90 percent effective in preventing the disease — the third promising breakthrough in the fight against a pandemic that has killed nearly 1.4 million people worldwide.
“This vaccine’s efficacy and safety confirm that it will be highly effective against Covid-19 and will have an immediate impact on this public health emergency,” Pascal Soriot, Chief Executive Officer, said in a statement.
