“Pfizer is open to collaborating with HHS on a distribution model that gives as many Americans as possible access to our vaccine as quickly as possible,” the company said in a statement Monday.

“With the pandemic worsening, and more contagious variants emerging around the world, this is not the time to be lifting restrictions on international travel,” she tweeted. “On the advice of our medical team, the Administration does not intend to lift these restrictions on 1/26. In fact, we plan to strengthen public health measures around international travel in order to further mitigate the spread of COVID-19.”

Trump issued a proclamation Monday night, announcing he will rescind travel bans for non-U.S. citizens from Brazil, the United Kingdom and much of Europe next week.

The travel bans were put in place at the start of the pandemic following calls from health officials who urged the president to stop the spread of the virus.

The restrictions will be removed starting Jan. 26, the same day that all travelers must present a negative coronavirus test or proof of recovery from COVID-19 to enter the United States.

“Public health officials in the jurisdictions have a proven record of working with the United States to share accurate and timely COVID-19 testing and trend data, and the United States has active collaborations with the jurisdictions regarding how to make travel safe between our respective countries,” the proclamation said.

The U.K. and Europe bans were instituted in March, while the Brazil ban was implemented in May.

LA Fire Department sees positivity rate plummet after most firefighters get vaccinated

“As expected, the vaccine began to have its impact seven to 10 days after the first vaccines were given,” Dr. Clayton Kazan, the department’s medical director, said in a statement. “This is the first time in the entire pandemic that our data diverged from that of the county,” he added.

This week, firefighters will start receiving their second dose of the two-dose vaccine.

WHO director criticizes deals between rich countries, vaccine makers

Tedros pointed to one of the lowest income countries in the world, which he did not name. “Just 25 doses have been given,” he said. “Not 25 million, not 25,000 — just 25. I need to be blunt: The world is on the brink of a catastrophic moral failure.”

The deals rich countries have made with vaccine producers are putting the effectiveness of COVAX, the WHO’s global vaccine-sharing program, at risk by driving up prices, according to Tedros. “This could delay COVAX deliveries and create exactly the scenario COVAX was designed to avoid, with hoarding, a chaotic market, an uncoordinated response and continued social and economic disruption,” he added.
