Vaccines against covid work but more people need to get the shots: US doctor

Vaccines work against Covid-19, including the highly contagious delta variant, but the challenge is in having enough people inoculated, according to a professor of preventive medicine at Vanderbilt University School of Medicinal.

“Let him in the refrigerator no help, that won’t prevent the disease. you have to move that vaccine in weapons, “said William Schaffner on CNBC’s “Squawk Box Asia” on Monday.

Data collected by online scientific publication, Our World In Data, showed about 22.6% of the world’S population at least received one dose of a vaccine against Covid-19 – but most of they are in high income, rich wealth countries in North America and Western Europe.

Less than 1% of people in low income countries at least received one dose.

Covid booster shots

is remains it is unclear whether those vaccinated against Covid-19 would require booster shots down the line.

A group of centers for Disease control and prevention scientists recently stated that there is not enough data at present for support recommending booster shots to the general population but that more vulnerable groups, such as the elderly people or transplanted, it can need one dose in more.

Schaffner said that need for lure shots would depend on two things.

“Duration of protection of our current vaccines, yet to be determined but so far so good, and the other is, if new variants develop that can evade the protection of our current vaccines, “he said, adding that such variants have yet to appear.” We just must obtain (Covid vaccines) more accepted in the population. “

The coronavirus has mutated many times since the pandemic started last year.

A variant that experts believe poses a serious threat to the elimination of Covid-19 is the delta, a virulent strain that was first detected in And India has since swept the world for over 90 countries. Delta is becoming the dominant variant of the disease globally and has been declared a “variant” of concern “of the World Health Organization.

Vaccination hesitation

Lot of countries we are facing vaccination hesitation, in partly due to widespread misinformation about the shots.

Also in the United States, where more 50% of the population received at least one dose of vaccine, inoculation efforts in some states have hit a wall as the delta variant spreads rapidly in all over the country. It could become a potential issue in set off of the United States, in particular in rural areas, where the spread of vaccination remains low, doing more people vulnerable to the delta variant.

We are a risk of new variants that can circumvent the protection of our vaccine more the virus spreads. Not just here in in the United States, but everywhere around the world.

Schaffner said that while the United States is in a “slightly better position” to face the new variant, it is far from ideal. He explained that in some areas, the vaccination level achieved is between half 20% and half 30%, while ideal range to stop the spread of the delta variant is between 70% and 80%. Lot of people who are hospitalized in hospital due to Covid-19 are not vaccinated or are partially vaccinated, according to Schaffner.

“The more transmission that occurs, the more new people who are infected, the more opportunity that the virus has to multiply. When it multiplies, it changes. And when it changes, it has the opportunity to create new variants, “he said.

“We are a risk of new variants that can circumvent the protection of our vaccine more the virus spreads. Not just here in in the United States, but everywhere around the world, “Schaffner added.
