Although existing Covid-19 vaccines have greatly helped prevent deaths, scientists now need to train their focus on developing a strike that stops the virus from spreading, according to a leading Oxford scientist. Vaccines against Covid have led to a sharp drop in deaths and severe viral illnesses, but the virus, which continues to spread, is still a concern around the world. “We need a new vaccine to stop the transmission, and there are many interesting ideas, “Sir John Bell, a professor of medicine at Oxford University, was quoted as saying by the Guardian.” Deaths from the disease, these truly horrific deaths, were largely eliminated by the end of spring (2021) and they were moving forward, at a very low level and very close to the starting level, and have continued to thunder almost in a straight line ever since, “he added. But as new options emerge, the effectiveness of vaccines is declining, increasing the risk.
“It’s interesting to see if any of the (current) vaccines have a long-term future,” Bell said. “None of them are very good at stopping shows,” he said, and as options emerged, “they get less good over time” in preventing people from getting sick. He said that instead of trying to get vaccinated every time a new option comes up, it is best to develop something that can limit the spread and not harm people, the report said.
Although vaccine manufacturers have created booster doses for the elderly, the immunologist said the booster had no effect on deaths, despite all the rah-ra, suggesting that two doses of the vaccine were enough to prevent death and serious disease.
Bell nodded in favor of another round of booster vaccines for those over 65 and vulnerable people with poorer immune systems, but he was “not very enthusiastic” to offer re-vaccinations to healthy younger people, children and teenagers, except unless a more serious version of Covid comes along “Their risk of serious illness is low with Covid and they almost never die. If we had a great vaccine to block transmission, then having children would make sense, but we don’t. Most of the world will get Covid, you have to get used to it. ” He described the “very high” chance that each new variant would be relatively light, such as Omicron, while the chances of a more deadly variant being “very low, but nothing.” “We need to look for a highly pathogenic option that can start killing people on a large scale and avoid a vaccine response, but today we see no signs of that,” Bell said.
