England’s Deputy Chief Medical Officer said people who have been vaccinated against COVID-19 are still able to pass the virus to others. Professor Jonathan Van Tam urged the vaccinated people to follow the restrictions, saying that scientists “do not yet know the effect of the vaccine on transmission.”
Van Tam, writing in the Sunday Telegraph, claimed that vaccines offer “hope,” but that the focus must remain on reducing infection rates.
Earlier, British Health Secretary Matt Hancock claimed that 75 percent of people over the age of 80 had received their first dose of the virus.
The Pfizer-BioNTech and Oxford-AstraZeneca vaccines require two doses. Hancock added that three-quarters of care homes have also been vaccinated.
Van Tam added that “there was no effective vaccine at all,” so there may be no guaranteed protection against the virus.
In the weeks immediately following immunization, people can contract the virus. He suggested that people allow “at least three weeks” to develop an immune response in the elderly.
Professor Van Tam said: “Even after taking two doses of the vaccine, you can still give Covid-19 to another person and the chains of transmission will continue after that.”
He added: “If you change your behavior, you can continue to spread the virus, keep the number of cases high, and put others at risk who also need a vaccine but are in line.”
Last week, the person involved in the Israeli response to the Coronavirus claimed that a single dose of the Pfizer vaccine might simply not be effective.
Even so, Israel has one of the highest vaccination rates in the world. Scientists around the world use data from Israel as a benchmark to ensure a vaccine is effective, especially when it is administered to the entire population.
It is possible for people to “still get sick” after receiving an experimental vaccine from any vaccine, said Yuli Edelstein, the country’s health minister.
But the minister claimed that there are “encouraging signs of the presence of less serious diseases,” adding that fewer people are receiving treatment in hospital after receiving the first vaccine.
