London, Jan 24 (IANS): People who have received Covid-19 injections could still pass the virus on to others, warned UK Deputy Chief Medical Officer Jonathan Van-Tam.
According to Van-Tam, people should continue to follow the blocking rules.
Van-Tam noted 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 Sunday.
“Even after you have received both doses of the vaccine, you may still give Covid-19 to someone else and the chains of transmission will continue,” he said.
The expert also said that “no vaccine has been” 100 percent effective, so there is no guaranteed protection.
It’s possible to contract the virus within two to three weeks after receiving a needle stick, he said, and it is “best” to allow “at least three weeks” for an immune response to develop fully in older people. the report said.
The warning comes as the UK posted another high daily death toll from the virus of 1,348 this weekend, bringing the country’s total to 97,329.
According to the report, senior doctors have asked health officials in the UK to bridge the gap between the first and second doses of the Pfizer-BioNTech vaccine.
The maximum wait was extended from three to 12 weeks for the first hit to reach more people across the UK.
But the British Medical Association said the policy was “difficult to justify” and the gap should be reduced to six weeks.
