London, January 24 (IANS) People who have been injected with Covid-19 could still transmit the virus to others, UK Deputy Medical Director Jonathan Van-Tam has warned.
According to Van-Tam, people should continue to follow the foreclosure rules.
Van-Tam stressed that scientists “do not yet know the impact of the vaccine on transmission.” He said vaccines offer “hope” but infection rates must drop quickly, the BBC reported on Sunday.
“Even after receiving both doses of the vaccine, you can still give Covid-19 to someone else and then the chains of transmission will continue,” he says.
The expert also said that “no vaccine has ever been” 100% effective, so there is no guaranteed protection.
It is possible to contract the virus within two to three weeks of receiving a vaccine, he said – and it is “best” to allow “at least three weeks” for an immune response to develop. fully in older people, the report says.
The warning comes as the UK recorded another high daily death toll from the virus of 1,348 over the weekend, bringing the country’s total to 97,329.
Senior doctors called on health officials in the UK to close the gap between the first and second dose of the Pfizer-BioNTech vaccine, according to the report.
The maximum wait has been extended from three to 12 weeks for the first shot to be distributed to more people across the UK.
But the British Medical Association said the policy was “difficult to justify” and the gap should be narrowed to six weeks.
