Vaccination is important to protect against a spreading variant first identified in India, Fauci says

There is not yet a booster vaccine trial underway specific to the Delta variant, but variant-specific boosters may be on the horizon, Fauci said.

A booster may focus on a specific variant, or the type a person was originally vaccinated against, he said.

“We are approaching both of those, but the one thing that we are noticing that’s important is that the higher your degree of immune response against the wild type, the greater the secondary coverage you have against a wide array of variants,” he said. “You can boost against the wild type, and still cover variants, including 617.”

Vaccination numbers have plummeted since April

Since then, the numbers have plummeted. Over the past week, an average of roughly 560,000 Americans have been vaccinated each day.

Mississippi is the state with the lowest percentage of its population fully vaccinated — 27.5% as of Monday, according to the CDC.

Alabama has the second-lowest percentage of fully vaccinated residents among all states — 29.4% as of Monday, according to CDC data.

“I understand that in the short run we may get away with it, having slow vaccination rates,” said Dr. Ashish Jha, dean of the Brown University School of Public Health.

“But those people really are vulnerable — once we have more variants circulating in the United States — to get reinfected and potentially get very sick.”

Even those who’ve already had coronavirus should get vaccinated because research shows immunity achieved through vaccination is better than immunity through previous infection, Fauci said.

“We need to get vaccinated because vaccines are highly efficacious. They are better than the traditional response you get from natural infection,” Fauci said last month.

Lab research shows those who previously had Covid-19 and received two doses of an mRNA vaccine “had interesting, increased protection against the variants of concern,” he said.

And those relying on their immunity from previous infection need to understand the danger of new variants, Jha said.

“This is a bit of a misunderstanding that unfortunately a lot of people have … this idea that if you’ve been infected that you have natural immunity that you don’t need to get vaccinated,” Jha said.

“There is no doubt about it in my mind that a vaccine-induced immunity is much more durable and is going to hold up much better against the variants.”

Rare breakthrough infections have milder outcomes

But even those who get infected down the road after getting vaccinated will likely be less miserable than if they hadn’t gotten vaccinated at all.

CDC data published research Monday showing those who had rare “breakthrough” infections after one or two doses of vaccine had 40% less virus in their bodies and were 58% less likely to have a fever.

They also spent two fewer days in bed than unvaccinated Covid-19 patients, according to the study.

“The only way to be protected is to be fully vaccinated,” Jha said.

For those taking the Pfizer/BioNTech or Moderna vaccines, “This is why everybody needs a second dose.”

Moderna says 5-year-olds could get vaccine by the fall

Monday, Moderna CEO Stéphane Bancel said its vaccine will likely be available to children as young as 5 by the early fall.

“I think it’s going to be early fall just because we have to go down in age very slowly and carefully,” Bancel said at an event hosted on the social media platform Clubhouse.

Bancel said the process will take time as it determines the appropriate dosages for small children. “We anticipate data available in the September/October time frame,” he said.

The US added more than 16,000 new Covid-19 cases in children between May 27 and June 3, which is the lowest number of new child cases in a week in nearly a year, according to data published Monday by the American Academy of Pediatrics.
