US Centers for Disease Control and Prevention Director Dr. Rochelle Walensky emphasized that the Covid-19 vaccines are safe and effective, saying the risk of getting sick with the virus is higher than having an anaphylaxis reaction.
"I want to take a moment here to emphasize that the Covid-19 vaccines are safe and they work. And this is backed up with data," Walensky said at the White House Covid-19 Response Team's first press briefing on Wednesday.
She said that based on recent data, there were 2.1 cases of anaphylaxis per million doses administered of the Moderna vaccine. For the Pfizer vaccine, data showed 6.2 cases of anaphylaxis per million doses.
"Let me be clear, these are rare, treatable outcomes and the Covid-19 vaccines are safe. It's also important to put this into context. The risk with getting sick with Covid-19 are much higher than the risk of allergy or anaphylaxis from the vaccine," she said.
"While anaphylaxis can be scary, there are effective treatments, and patients generally do quite well," she added.
Walensky also said it is important to remember that there may be some side effects with the vaccine, including things like feeling feverish or having muscle aches.
"These are all normal and expected part of getting a vaccine, especially the second dose. These symptoms mean your immune system is revving up and the vaccine is actually working," she said.
Some background: President Joe Biden announced a plan to buy 200 million more Covid-19 vaccine doses from Pfizer and Moderna to fully vaccinate the American population by the end of summer or early fall of 2021.
Biden said on Monday that he expects that the US will soon be able to vaccinate 1.5 million people a day, raising the bar by roughly 500,000 more vaccinations than its target of one million per day in his first 100 days in office. He said that the US could surpass that initial target in about three weeks.
