Congress’s coronavirus patients show that one dose of vaccine may not protect against infection.



“Early prevention of COVID-19 can be around 12 days after a single dose,” said Naor Bar-Zeev, infectious disease physician and epidemiologist at the Johns Hopkins Bloomberg School of Public Health. “I shouldn’t think I was truly protected until a week or two after two doses.”

Although the vaccine may prevent patients from showing symptoms But those who get the vaccine may still be susceptible to infection, he said, which is why officials are urging newly vaccinated people to follow public health advice such as washing their hands and wearing masks.

“We have to keep wearing masks and keep our distance, especially after the first dose and even after the second dose,”

; said Nicole Lieberman, an immunology researcher at the University of Washington.

Both Pfizer and Moderna vaccines were approximately 95 percent effective after two doses, according to the company.Pfizer’s vaccine consisted of two doses, three weeks apart, and Modena had two doses of 28 days apart.

Rep. Bonnie Watson Coleman (DN.J.), Bradley Schneider (D-Ill.) And Pramila Jayapal (D-Wash.) Tested positive this week. The three lawmakers said they received the first coronavirus vaccine in the days before the Jan. 6 riots.

Coleman is a 75-year-old cancer survivor who said the trip to D.C. last week was the first in months. She wrote in an editorial for The Washington Post. She was concerned about it because others in the Capitol might “disrespect their social allegiances and practices.” Coleman received his first vaccine on December 29.

Schneider drove from his home near Chicago to Washington to avoid flying as his wife had a health condition that made her more susceptible to the virus. Schneider was first shot on Jan. 4, two days before the attack. He did not report positive symptoms after the diagnosis.

Jayapal also received her first shot on Jan. 4, the day between the shooting and her lockup had negative test results, a spokesman said.

“Even if the member in question has been vaccinated But their bodies didn’t have time to react, ”Lieberman said.

At least 10.3 million coronavirus cases have been vaccinated nationwide, according to Washington Post. The images come amid a worsening outbreak, with more than 4,000 deaths from COVID-19 on Wednesday. More than 225,000 new cases have been reported.

Lawmakers were among those gathered in a crowded room after the government shutdown last week. Although large But rooms without windows were too full for people to be far away, and residents – including some without masks – spent hours together.

The attending physician’s office at the City Hall said on Sunday lawmakers may have been exposed to people infected with the coronavirus while in the state. “Separation of protection”

Coronavirus genetic testing, if the sequences are matched, can help confirm whether the three lawmakers’ cases are relevant. “Without a sequence to verify who is a zero-tolerance patient, we cannot know exactly. Of course, ”Lieberman said.

But she and other experts said the simplest explanation, considering the situation, was that the virus was spreading in a closed room.

“It is highly probable, and I think it is quite probable that this is a widespread event and that these lawmakers were caught by spending time in the room,” said Joseph G. Allen, a researcher at the University of California. Harvard Environmental Health said.

Krystal Pollitt, a professor of environmental health sciences at Yale University, said as she watched lawmakers’ live feed before they were moved to a safe location, how dangerous was it “everything that could” was in her mind? In transmitting the virus.

“People are making their voices without masks – there are many people in the area,” Pollitt said. “You see people sitting opposite each other; They were exactly what others said. “

Representative Marjorie Taylor Greene (R-Ga.) Told Fox News that she and her colleagues had rejected the masks because they had no symptoms.

Green told the Washington Post in an email, “It is absolutely ridiculous and ridiculous to blame those of us for not having COVID or having symptoms.”

But as the asymptomatic people spread the virus, health workers urged everyone to wear masks in public areas, regardless of whether they feel healthy or not.

Pollitt said, based on a rough estimate, “you could have a fairly large number of infections” within 90 minutes, she said.

Even a well-functioning HVAC system will be pushed to its boundaries, Pollitt said, to adequately exchange air and prevent the spread of exposed people in closed rooms and without windows.

“If someone gets infected in that room, people will be infected,” said Allen. “This is just another aftermath of a truly shocking and unbelievable day in American history.”
