The World Health Organisation does not expect widespread vaccinations against COVID-19 until the middle of next year.
The World Health Organisation does not expect widespread vaccinations against COVID-19 until the middle of next year, a spokeswoman says, stressing the importance of rigorous checks on their effectiveness and safety.
US public health officials and Pfizer Inc said on Thursday a vaccine could be ready for distribution as soon as late October.That would be just ahead of the US election on November 3 in which the pandemic is likely to be a major factor among voters deciding whether President Donald Trump wins a second term.
This referred to the phase in vaccine research where large clinical trials among people are conducted. Harris did not refer to any specific vaccine candidate."A lot of people have been vaccinated and what we don't know is whether the vaccine works...at this stage we do not have the clear signal of whether or not it has the level of worthwhile efficacy and safety...," she added.
COVAX aims to procure and deliver 2 billion doses of approved vaccines by the end of 2021, but some countries that have secured their own supplies through bilateral deals, including the United States, have said they will not join.
