Mayo Clinic Q&A: Bringing COVID-19 Vaccines to the Public
Once a vaccine to prevent COVID-19 is approved, there will be logistics to consider. For example, who will receive the vaccine first, and how can the supply chain safely deliver the vaccine to 330 million Americans and potentially more than 7 billion people worldwide? In addition, multiple vaccines may be brought to market within weeks to months of each other, confusing consumers. (Published 9/16/2020)

Mayo Clinic Q&A: COVID-19 Vaccine Trials Update
While the number of COVID-19 cases continues to surge, there is positive news on the vaccine front. In early clinical trial data, two vaccines have now shown at least 90% effectiveness in reducing the risk of infection from the virus that causes COVID-19. While more time and research is needed to understand how long the immunity from a vaccine lasts, experts believe a vaccine could be approved for emergency use authorization before the end of the year.

Mayo Clinic Q&A: How Messenger RNA Vaccines Work
The first COVID-19 vaccines to reach the market are likely to be messenger RNA vaccines or mRNA. According to the Centers for Disease Control and Prevention, mRNA vaccines work by teaching cells in the body how to make a protein that triggers an immune response. Unlike many vaccines that use a weakened or inactivated form of a virus, mRNA vaccines do not use the live virus that causes COVID-19. (Published 12/02/2020)

Mayo Clinic Q&A: COVID-19 Vaccine Update
Last week, the first COVID-19 vaccine was approved for emergency authorization use in the United Kingdom. Meanwhile in the U.S., plans are being made to distribute COVID-19 vaccines, pending approval by the Food and Drug Administration. The Advisory Committee on Immunization Practices, a committee within the Centers for Disease Control and Prevention, recommends that health care workers and elderly people living in long-term care facilities receive top priority for COVID-19 vaccination in the U.S. (Published 12/09/2020)

Mayo Clinic Q&A: A Vaccine Milestone
The Food and Drug Administration and Centers for Disease Control and Prevention have approved the first of several COVID-19 vaccines developed in response to the pandemic. The first vaccine has been distributed to all 50 states, and vaccinations are underway. The development of safe and effective COVID-19 vaccines has been an extraordinary effort of science and engineering. "This is a milestone human achievement by any measure," says Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group. (Published 12/16/2020)

Mayo Clinic Q&A: Don't Hesitate, Dive into Data for COVID-19 Vaccine
The news about COVID-19 vaccines being approved, distributed and administered so quickly is causing concern for some people — what is often referred to as vaccine hesitancy. "We have always struggled with vaccine hesitancy and a sense of uncertainty," says Dr. Robert Jacobson, a Mayo Clinic pediatric infectious diseases expert and director of Mayo Clinic's Primary Care Immunization program. "But what we have available through this emergency use authorization is worth taking now. I would not delay doing what I could to protect my patients and myself." In this Mayo Clinic Q&A podcast, Dr. Jacobson dives into the data, detailing how the randomized controlled trials worked. He also answers questions about COVID-19 vaccines for children and pregnant women, explains why the vaccine doesn't change your genetic makeup and much more. (Published 12/17/2020)

Mayo Clinic Q&A: COVID-19 Vaccinations Happening in Phases
Front-line health care workers across the country are receiving the first COVID-19 vaccinations. With the recent approval of a second COVID-19 vaccine for use here in the U.S., more COVID-19 vaccine doses are expected to be available this week. A Centers for Disease Control and Prevention panel has recommended allocating COVID-19 vaccines for the next phase. Phase 1b includes those who are 75 and older as well as front-line essential workers, including police, firefighters, teachers and grocery store workers. These vaccinations would begin when phase 1a, health care workers and long term care residents, is completed. (Published 12/23/2020)

Mayo Clinic Q&A: Expert updates on COVID-19 vaccines
The U.S. rollout of COVID-19 vaccines is reportedly ramping up with the news that nearly all available doses will soon be released to the American public. "The new COVID-19 variants are traveling quickly, and this is a warning that we need to take precautions," says Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group. Dr. Poland says these new variants are a consequence of an RNA virus being transmitted from human to human. "Even after we get our vaccines, we still need to wear masks out in public. We still need to maintain physical distancing. And we still need to wash our hands until about 80% of people get their COVID-19 vaccines," Dr. Poland emphasizes. (Published 01/13/2021)

Mayo Clinic Q&A: COVID-19, vaccines and children
The distribution kinks for COVID-19 vaccines are getting ironed out, says Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group."It's a logistics nightmare, but now you're seeing a plan to administer 1 million doses a day and I think that's very achievable," says Dr. Poland. "And the production of the vaccine is just going to accelerate." Dr. Poland also repeats the reminders about preventing transmission of COVID-19: Wear a mask. Wash your hands. Keep your social distance. "The current estimates are that in the next four weeks, we'll probably have about another 100,000 deaths," adds Dr. Poland. "It's stunning when you think about 1 out of every 860 Americans has now died of this." (Published 01/20/2021)

Mayo Clinic Q&A: COVID-19 virus, variants and vaccines update
When it comes to the COVID-19 pandemic, Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group, says there's some good news. "Case numbers are falling, masking and distancing do work, and we can control this if we do it right." However, the not so good news is that variants are showing up in over 30 countries and are reportedly more transmissible. There also seems to be a reduction in vaccine efficacy against the new variants. "This is a desperate race between vaccine and virus, between time and opportunity, and we dare not lose that opportunity," emphasizes Dr. Poland. (Published 02/03/2021)

Mayo Clinic Q&A: Answering Questions about COVID-19 Vaccines
As new COVID-19 variants spread and more people are vaccinated for COVID-19, people have more questions about COVID-19 vaccines. Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group, says that's understandable with new information released every day. For instance, people are wondering what type of medications they can take if they're being vaccinated for COVID-19. There are also concerns about whether a person who has been vaccinated for COVID-19 can transmit the virus. And some are asking why they need to wait 14 days, before and after being vaccinated for COVID-19, if they are scheduled to be given a different vaccine, such as a shingles vaccine.

Mayo Clinic Q&A: Rapid pace of COVID-19 vaccinations
Millions of people in the U.S. are being vaccinated for COVID-19. However, the discussion is ongoing as to whether people who are immunocompromised, such as patients undergoing cancer treatment, or people who have autoimmune diseases, should be vaccinated for COVID-19. "Both of those categories (of people) should be vaccinated," says Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group. "Those are not contraindications. Those are indications to get the vaccine." He adds that research is ongoing, but current information demonstrates the benefits far outweigh the theoretical risks. (Published 03/17/2021)
