Dear Commons Community,
The world was elated on Monday when Pfizer announced that it was close to developing a vaccine for stemming the spread of Covid-19. An article by NBC News this morning cautions that the Pfizer vaccine might have flu-like side effects including sore arms, muscle aches and fever — that could last days and temporarily sideline some people from work or school. Furthermore, even if the vaccine proves 90 percent effective, the rate Pfizer established for its product, 1 in 10 recipients would still be vulnerable. That means, at least in the short term, as population-level immunity grows, people can’t stop social distancing and throw away their masks. In sum, if the vaccine is approved for distribution in the next month or so, we will be well into 2021 before we can begin thinking that our lives will be back to normal..

Covid-19 vaccine may have unpleasant side effects. That will mean it’s working.

Pfizer is expected to seek federal permission to release its Covid-19 vaccine by the end of November, a move that holds promise for quelling the pandemic but also sets up a tight time frame to make sure consumers understand what it will mean to get the shots.
The vaccine, and likely most others, will require two doses to work, injections that must be given weeks apart, company protocols show. Scientists anticipate that the shots will cause enervating flu-like side effects — including sore arms, muscle aches and fever — that could last days and temporarily sideline some people from work or school. And even if a vaccine proves 90 percent effective, the rate Pfizer touted for its product, 1 in 10 recipients would still be vulnerable. That means, at least in the short term, as population-level immunity grows, people can’t stop social distancing and throw away their masks.
Left out so far in the push to develop vaccines with unprecedented speed has been a large-scale plan to communicate effectively about those issues in advance, said Saad Omer, director of the Yale Institute for Global Health.
“You need to be ready,” he said. “You can’t look for your communication materials the day after the vaccine is authorized.”
Omer, who declined to comment on reports that he’s being considered for a post in the new administration of President-elect Joe Biden, called for the rollout of a robust messaging campaign based on the best scientific evidence about vaccine hesitancy and acceptance. The Centers for Disease Control and Prevention has created a strategy called “Vaccinate with Confidence,” but it lacks the necessary resources, Omer said.
“We need to communicate, and we need to communicate effectively, and we need to start planning for this now,” he said.
Such broad-based outreach will be necessary in a country where, as of mid-October, only half of Americans said they’d be willing to get a Covid-19 vaccine. Initial doses of any vaccine would be limited at first, but experts predict they may be widely available by the middle of next year. Discussing potential side effects early could counter misinformation that overstates or distorts the risk.
“The biggest tragedy would be if we have a safe and effective vaccine that people are hesitant to get,” said Dr. Preeti Malani, chief health officer and a professor of medicine at the University of Michigan in Ann Arbor.
Pfizer and its partner, the German company BioNTech, said Monday that their vaccine appears to protect 9 in 10 people from getting Covid-19, although they didn’t release underlying data. It’s the first of four Covid-19 vaccines in large-scale efficacy tests in the U.S. to have posted results.
Data from early trials of several Covid-19 vaccines suggest that consumers will need to be prepared for side effects that, while technically mild, could disrupt daily life. A senior Pfizer executive told the news outlet Stat that side effects from the company’s vaccine appear to be comparable to those of standard adult vaccines but worse than those of the company’s pneumonia vaccine, Prevnar, or typical flu shots.
The two-dose Shingrix vaccine, for instance, which protects older adults against the virus that causes painful shingles, results in sore arms in 78 percent of recipients and muscle pain and fatigue in more than 40 percent of those who take it. Prevnar and common flu shots can cause injection-site pain, aches and fever.
“We are asking people to take a vaccine that is going to hurt,” said Dr. William Schaffner, a professor of preventive medicine and health policy at Vanderbilt University Medical Center. “There are lots of sore arms and substantial numbers of people who feel crummy, with headaches and muscle pain, for a day or two.”
Persuading people who experience those symptoms to return in three to four weeks for a second dose — and a second round of flu-like symptoms — could be a tough sell, Schaffner said.
How public health experts explain such effects is important, Omer said. “There’s evidence that suggests that if you frame pain as a proxy of effectiveness, it’s helpful,” he said. “If it’s hurting a little, it’s working.”
At the same time, good communication will help consumers plan for such effects. A Covid-19 vaccine is expected to be distributed first to health care staffers and other essential workers, who may not be able to work if they feel sick, said Dr. Eli Perencevich, a professor of internal medicine and epidemiology at University of Iowa Health Care.
“A lot of folks don’t have sick leave. A lot of our essential workers don’t have health insurance,” he said, suggesting that essential workers should be granted three days of paid leave after they’re vaccinated. “These are the things a well-functioning government should provide for to get our economy going again.”
Making sure consumers know that a vaccine is likely to require two doses — and that it could take a month for full effectiveness to kick in — is also crucial. The Pfizer phase 3 trial, which has enrolled nearly 44,000 people, started in late July. Participants received a second dose 21 days after the first. The reported 90 percent efficacy was measured seven days after the second dose.
Communicating effectively will be vital to ensuring that consumers follow through with the shots and — assuming several vaccines are approved — that their first and second doses are from the same maker. Until full protection kicks in, Omer said, people should continue to take measures to protect themselves: wearing masks, washing hands, socially distancing. It’s important to let people know that taking appropriate action now will pay off later.
“If we just show them the tunnel, not the light, then that results in this mass denial,” he said. “We need to say, ‘You’ll have to continue to do this in the medium term, but the long term looks good.'”
The best communication can occur once full data from the Pfizer trial and others are presented, said Dr. Paul Offit, a vaccinologist at Children’s Hospital of Philadelphia who sits on the Food and Drug Administration’s advisory board considering Covid-19 vaccines.
“When you look at those data, you can more accurately define what groups of people are most likely to have side effects, what the efficacy is, what we know about how long the efficacy lasts, what we know about how long the safety data have been tested,” he said. “I think you have to get ready to communicate that. You can start getting ready now.”
Enduring “flu-like side effects including sore arms, muscle aches and fever” would be worth it for me to be able to hug you again Dad. Love you…can’t wait to be able to be with you again. Stay safe, stay healthy..wear a mask people!!!
Thank you, Dawn
I cannot wait to hug you and your wonderful family also. Hopefully, some day soon. Elaine and I have already decided that we will be among the first to take the vaccine
Stay safe and with much love!
freedom from the virus
