LONDON: The Delta variant that is very transmitting from Covid-19 has made the prospect of a flock of immunity, where most of the population of a country becomes immune to the virus, it is difficult, the head of the British Oxford vaccine group has warned.
Professor Andrew Pollard, who led the team behind the Covid-19 vaccine University of Oxford, told the All-Party Parliament Group (APPG) in Coronavirus on Tuesday that fear of other variants of more transmitting was still possible and therefore nothing could be right -Tar stopped the deadly virus from the spread.
However, he also said there was no reason to “panic” when he expressed doubts for the third dose of the third booster vaccine proposed by the government in the UK.
“This problem with this virus is (that) not measles.
If 95 percent of people are vaccinated against measles, the virus cannot transmit in the population,” Prof.
Pollard explained during the online proof session.
“The Delta variant will still infect people who have been vaccinated.
And that means anyone who is still not vaccinated at a time will meet the virus.
We do not have anything that will stop the transmission, so I think we are in a situation where the herd immunity is not possibilities And I suspect the virus will vomit a new variant that is even better at infecting vaccinated individuals, “he said.
It echoes by Paul Hunter, professor in medicine at the University of Anglia Timur and an infectious disease expert, which also highlights that the current vaccine given is very effective in preventing Covid-19 and severe death but they cannot prevent infection.
“The concept of a herd of immunity cannot be achieved because we know the infection will spread in a population that is not vaccinated and the latest data shows that two doses may only be 50 percent protective on infection,” Hunter said.
Meanwhile, experts also burden the British Health Secretary Sajid Javid’s plans to start offering the most risky groups in the third booster shot from the Covid vaccine along with the flu vaccine from next month.
“Our time wou LD needs encouragement is if we see evidence that there is an increase in hospitalization – or the next step after that, which will be a dying person – among those who are vaccinated.
And that is not something we see at this time,” said Prof.
Pollard.
“Even when immunity levels began to fall, our immune system still remembers that we are vaccinated and we will remember decades from now that we have two doses of the vaccine.
So there is no reason at this time to panic,” he said, adding that the dose What is needed to “go where they can have the biggest impact” in parts of the world that are not vaccinated.
On Tuesday, England recorded the highest daily death toll from Coronavirus since March, with 146 new deaths, but the number of new cases fell to 23,510 from 25,161 on Monday.
