Those who are vaccinated protect themselves but can pass the virus on to another, suggests British expert

Those who are vaccinated protect themselves but can pass the virus on to

Those who have been vaccinated against coronavirus can pass it on to others. For this reason they must continue to follow the rules. This is warned by the expert and deputy chief medical officer in Britain. 

In an article in the Sunday Telegraph, expert Jonathan Van-Tam points out that scientists do not yet know the impact of the vaccine on the transmission of the virus. He said vaccines offer hope but the rate of infection should be reduced as soon as possible. According to him no vaccine has ever been 100% effective, so there is no guaranteed protection. The expert believes that the virus is transmitted two to three weeks after vaccination. 

'I think the blockage should continue for at least three weeks, once we have a complete immune response in older people. Even after you have received both doses of the vaccine, you can still pass Covid-19 to someone else and the transmission chains will continue. "If you change your behavior, you can still spread the virus, keeping the number of cases high and putting others at risk who also need the vaccine but have to wait in line."

This week, doctors called on health officials in England to close the gap between the first and second doses of the Pfizer-BioNTech vaccine. Maximum waiting was extended from three to 12 weeks. More than 5.8 million people in the UK have received the first dose of the vaccine.
