ROCHESTER, Minn. — A pair of Mayo Clinic studies shed light on something that is typically difficult to see with the eye: respiratory aerosols. Such aerosol particles of varying sizes are a common component of breath, and they are a typical mode of transmission for respiratory viruses like COVID-19 to spread to other people and surfaces.
"In the last month or so we have seen Pfizer release some really exciting data in the 12- to 15-year age group from their clinical trial that showed the vaccine to be highly effective — 100% effective in that trial — and very well-tolerated in that age group without any serious side effects," says Dr. Nipunie Rajapakse, a Mayo Clinic pediatric infectious diseases specialist.
DEAR MAYO CLINIC: A friend of mine shared that she went for her annual mammogram last week. At the appointment, she was asked whether she had been vaccinated for COVID-19 and had experienced any changes in her breasts. I recently received my first dose of a COVID-19 vaccine. Although I feel fine, I'm wondering if there is a connection between being vaccinated for COVID-19 and increased risk for breast issues? I am due for my mammogram appointment in a few weeks.
"I wanted to get it mainly so, hopefully, we can all stop (wearing) our masks and finish this up. I got an internship coming up, and I want to make sure I'm all good to go. Hopefully by next school year, I can be back in class with all my friends," says Nick Cunningham, a Mayo Clinic patient.
COVID-19 cases are falling in the U.S. because 245 million doses of one of the available COVID-19 vaccines have been administered, according to Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group. "But at the same time, there are still people who need more information about the safety and the value of getting a COVID-19 vaccine," says Dr. Poland.
Throughout the COVID-19 pandemic, health care providers have been concerned about a growing number of patients delaying or skipping preventive screenings because they have been hesitant to see their health care provider. Experts have stressed that it's not only safe to come in for preventive screenings, but also it's important to avoid future health problems or catch them early when they are easier to treat.
