covid vaccine works But people need more injections: US doctors

A professor of preventive medicine at Vanderbilt University School of Medicine says vaccines are working against COVID-19. This includes the highly contagious delta variant. But the challenge lies in getting people to get enough vaccines.

“Leaving it in the refrigerator doesn’t help. That doesn’t prevent disease. You have to move that vaccine into your arms,” William Schaffner told CNBC’s Squawk Box Asia on Monday.

Data compiled by the online scientific publication Our World In Data shows that approximately 22.6% of the world̵

Less than 1% of people in low-income countries have earned at least once.

It is unclear who vaccinated against COVID-19. Should I have a booster vaccination?

Recently, a group of scientists at the Centers for Disease Control and Prevention said there was not enough data to support the introduction of supplemental shock to the general population. But the weaker groups, such as the elderly or transplant recipients. may need additional medication

Schaffner said the need for a booster shot would depend on two things.

“The timing of our current vaccine protection still under consideration But so far still good and another case is Is there a new strain being developed that can evade the protection of our current vaccine?” he said, adding that such strain has not yet appeared. (Covid vaccine) is more acceptable in the population.”

The coronavirus has mutated several times since it started last year.

One variable that experts say is a major threat to eradicate Covid-19 is Delta, a virulent strain that was first detected in India and has spread across more than 90 countries around the world. of diseases around the world and has been declared as “Worrisome variables” by the World Health Organization.

vaccine hesitant

Many countries are facing vaccine reluctance. This was partly due to misinformation about vaccinations.

Even in the United States, where more than 50% of the population has been vaccinated at least once. Inoculation efforts in some states also collapsed as the delta variant spread rapidly across the country. It can become a problem that can occur in different parts. of the United States especially in rural areas which vaccination remains low This makes more people vulnerable to delta variables.

We are at risk of developing new models that can circumvent the defenses of our vaccines. The more the virus spreads Not just here in the United States. but everywhere around the world

Schaffner said that while the United States is in a “quite better position” to deal with the new variables, But still far from ideal. He explained that in some areas The level of vaccination given is between -20% and mid-30%, while the ideal range to stop the spread of the delta variant is about 70% to 80%. Hospitalization due to COVID-19 not vaccinated or partially vaccinated According to Schaffner

“The more the infection is spread, the more new people infected, the more likely the virus will multiply. when it multiplied it was mutated and when it mutates It also has the opportunity to create new species,” he said.

“We are vulnerable to new strains that can evade the protection of our vaccines. The more the virus spread Not just here in the United States. But everywhere around the world,” Schaffner added.
